Dxf to xyz arrays positions
NI Motion assistant
Version 2.6
Labview full development system 2012
I need to read a CAD file and export the XYZ coordinates.
Problem :
It's possible with Motion assistant to enter a dxf file and to export XML file.
After this I can to work with the xml file to export the array of xyz position.
The problem is, without Motion Assistant it's not possible to create the xml file.
how can i in block diagram of labview export XML file from DXF?

Send me a pm, I have a cad program that can read dxf files and spit out the coordinates. Is this a one time thing or do you need to do it over and over?
Or you could look at something like this
http://www.ransen.com/pointor/DXF-to-XYZ.htm
Another post by unclebump that came up in a different search... This is getting strange.
unclebump, I have a need for the functionality to output labview x/y coordinates to a DXF. The current method is to print out the coordinates and have another engineer plot them in SolidWorks. I would like to streamline this by outputting the DXF in LabVIEW. Is there a way to do this?
Thanks,

Displaying Array Position not working in case of descending Order?
Hi,
I need to display the array position of the sorted array in Descending order. Here is my code.
int[] in = {5,3,2,7};
int[] newArr = new int[in.length];
int[] na = new int[in.length];
//copying into a new array
for(int i=0;i<in.length;i++){
newArr[i] = in;
// code for descending order
for(int j=0;j<in.length;j++){
Arrays.sort(in);
na[j] = in[in.length-(1+j)];
}the sorted array will be will be {7,5,3,2} now according to this i need to display the array position of the sorted array which should be {3,0,1,2} i tried to compare newArr[i] with na[j] but am not gettin the result that i should be getting the same comparison is working in case of Ascending Order but not descending. Any suggestions or help will be appreciated.
Thanks and regards.hi,
what you are doing is correct only, do not put sort method inside the for loop
and postion is correct also
int[] in = {5,3,2,7};
int[] newArr = new int[in.length];
int[] na = new int[in.length];
//copying into a new array
for(int i=0;i<in.length;i++){
newArr[i] = in;
Arrays.sort(in);
// code for descending order
for(int j=0;j<in.length;j++){
na[j] = in[(in.length-1)-j];
System.out.println("Val --> "+na[j]);
System.out.println("Position --> "+j); -
Problem in displaying Array Position?
hi,
I am having a problem in displaying the array position of a sorted Array
for ex:
int[] a = {4,3,1,7}for sorting the array i am using Arrays.sort(a); then the output will be
a = {1,3,4,7}now according to this i need to display the array position of a before sorting like a should have the output {2,1,0,3} which should be the array position of the sorted array. Any help will be appreciated.
Thanks.for (int i = 0 ; i < unsortedArray.length ; i++)
for (int j = 0 ; j < sortedArray.length ; j++)
if (unsortedArray[i] == sortedArray[j]) {
System.out.println("position for element "+i+" is "+j);
break;
}notice that if you have duplicate values, the position of the duplicate will always be considered as the first occurence of this value -
MMM1061: Corrupted array: position mismatch at 0
Hello
We got severes errors on Parent Mappings with Pluggable Mappings inside. We can Analyze and Deploy the Parent Mappings without any error, but we get errors on syncrhonizing the Parent Mappings.
1. Error on Synchronize a Parent Mapping (Pluggable Mappings inside)
Msg Box:
MMM1061: Corrupted array: position mismatch at 0.
MMM1061: Corrupted array: position mismatch at 0.
2. Error on closing the previously syncrhonized Parent Mapping
Msg Box:
INTERNAL ERROR: in MapGenerationLanguageValidator.validate(GENERATION_LANGUAGE, PLSQL)
3. Error on opening this or any other mapping:
Msg Box:
Repository Usage Error: Start nested transaction while already in one. Please contact Oracle Support with the stack trace and details on how to reproduce it.
All 3 msg boxes have a Detail button with a lot of Java function calls (too much to post it here).
What we tried so far (but all didn't help so far)
- Copy existing Pluggable Mapping and use this one in existing Parent Mapping
- Removing Pluggable Mapping from Parent Mapping and the include it again
- Recreating Pluggable Mapping from scratch and include it in Parent Mapping
- Rebuidling new Pluggable Mapping from scratch and also new Parent Mapping, using the newly created Pluggable Mapping
- Making sure all developers accessing the OWB Repository have the same language settings (English)
The only thing that helped so far was creating a dummy Pluggable Mapping/Parent Mapping NOT using (including) any other existing objects from this Repository (like tables, etc.)
The sync strategy (merge, update) has no influence whether we can sync successfully or not.
My conclusion so far is:
a) We have a severe internal Repository problem
or
b) This OWB version doesn't properly support Pluggable Mappings/Parent Mappings.
Any1 already had the same problems? We are working with OWB Client 10.2.0.1.31 and Warehouse Builder Repository: 10.2.0.1.0
Any hint are welcome
Thank youHi,
I recommend using the latest OWB Patch 10.2.0.4. The first release of 10.2 was quite buggy concerning pluggable mappings. we did not use them in that version.

Why do panel array positions change when I move to a computer with LCD screen?
I wrote a program in the lab and then moved it to the production area which
has a computer with an lcd monitor. The program has 3 arrays of clusters on
the front panel and each contain both controls and indicators. When I moved
it to the production computer the 3 array moved somewhat from their proper
positions. Also, each one moved a different distance. I wanted them to be
aligned so I ended up moving them out of alignment on the uncompiled copy so
that the production copy would be aligned correctly. Is there something
funny about lcd screens? Labview property node reports they are already
aligned and of equal height. Is there a way of forcing the arrays to align
no mat
ter what computer it is installed on?I've seen this before. If the resolutions are different it scales certain fonts
differently causing your controls to move. You need to make sure your using a
common font type and size between them or change your resolution on your desktop
to match the lcd's.
You can check the font on both machines to match them. One might have Arial 13,
20, 28 and the other Ariel 14, 20, 26. If you pick 20 it will go back and forth
ok, properly scaled.

HI everyone I am looking for some help on an array problem.
I am reading in a text file that is in a line by line format eg.
apple
orange
pear
etc
The problem is that I want my array to increment each line. However each time a new line is read from the text file the array postion goes back to zero. Im assuming theres something wrong with my loop. Somebody please help!!!
String line;
String[] words;
int i;
try {
BufferedReader reader = new BufferedReader(new FileReader("wordlist.txt"));
while((line = reader.readLine()) != null){
words = line.split(" ");
for(i = 0; i < words.length; i++){
Arrays.sort(words);
//System.out.println(words);
if(findWord.equals(words[i])) {
Cap = "the word was found at position " + Arrays.binarySearch(words, words[i]);
test=true;
checkString();
reader.close();
I I read in
apple orange pear
carrot cucumber tomato
then apple[0] orange[1] pear[2]
but then this resets to 0 on new line i.e
carrot[0] cucumber[1] tomato[2]Correct me if Im wrong but I think I have created the
array out side the loop.Your original code declares the array outsid of the loop, but it doesn't create it. It just allocates a reference variable that will point to the aray.
Inside the loop, where you do words = split you're creating a new array each time. (And like I said, if there's only one word on a line, you don't need to spilt.)
As for putting the next
lines word into the array on each loop pass I do not
understand how to do this. Any help would be
appreciated?
for (int ix = 0; ix < numLines; ix++) {
arrar[ix] = the line that you just read
} Of course, if you're using the standard while (line != null) for loop control, then you can just skip the for part and create an index variable that you increment inside the body of the loop. -
Writing random array positions to file
Hi all.
I have an array of 1000 positions each consisting of a String.
I want to write the strings equally to two seperate text files which i have managed without any probs.
The problem is i want to write these strings in a total random order so each time its run different strings would end up in different files and in total different order.
i know how to generate a random number but not sure how to access all positions of the array but in random order.
Any help would be appreciated.
thanksThe Random class has methods that generate random ints.
You can use those ints to index the array and get the String from that position.

Is there a way to separate an array into it's positive and negative elements?
I'm working with an array, and I'd like to be able to seperate this array into it's positive and negative elements. I'd like to be able to store each of these values in two other arrays (positive and negative arrays if you will). If anyone could suggest an algorithm for doing this, I'd appreciate any help I can get.
Actually, if you slightly modify the VI in the example, you can use it as a sub-VI for your application. In the front panel, right-click the VI's icon located on the top-right of your VI. Then select "Show Connector" and add the necessary connetcors to the VI (One for the input and two for the output) for the VI so it can be used as a Sub-VI. Save it with a different name and location so you don't change the original.

Painting Graphics from an Array
I have a GUI that displays the Towers of Hanoi solution in a JPanel. Everything actually works except for a slight repainting issue.
Currently I am overriding the paint() function, I know that for my purpose using paintComponent() would probably be the better route, however that's not my issue...
The images (disks) in my JPanel are not redrawing properly, and I have no idea why...
Basically:
- I call setup() to set the number of disks and the co ordinates they should be drawn. (store them in an array)
- I call moveDisk() to change the co ordinates of each disk as they are being moved.
- then drawDisk() is called to go through the array of disks and print them.
currently paint() calls drawDisk() in order to display the current position of all the disks.
It seems to work fine for the first 2 moves, then disks start disappearing until there is one (the last disk) left...BUT if I print the co ordinates of the disks they seem to be correct, just not drawing.
could someone take a look at my code and see what is wrong?
below is the meat of the code, minus the GUI:

Sorry if my post was a little too cryptic...
"How do you know? You have a problem you can't solve. Anything could be your issue." Agreed. However, using the process of elimination and debug statments I have been able to narrow the scope of the issue.
"If you can't solve it by executing the code and adding debug statements how to you expect us to help."If I could solve but "executing code and adding debug statements" there would be no need to post the problem here.
"We don't know exactly what you are attempting to do."Trying to paint my graphics to a JPanel based on a set of co ordinates.
"We don't know why you are passing the Graphics object around."Why not? is it impossible to do it this way?
"The big problem is in the alogorithm you use to determine the location of each component."Who said you couldn't read minds?
"If you are using some kind of animation then I would use a Timer to schedule the moving of components. I don't even see how you are doing this in your code."Sorry I guess stating that I didn't post my entire code may have threw things off...I do use a timer in a seperate class. I will include it in the next post.
"I can't tell if you are using Threads of not."guess you overlooked these lines of code:

Need help with connecting file inputs to arrays
In this assignment I have a program that will do the following: display a list of names inputed by the user in reverse order, display any names that begin with M or m, and display any names with 5 or more letters. This is all done with arrays.
That was the fun part. The next part requires me to take the names from a Notepad file, them through the arrays and then output them to a second Notepad file.
Here is the original program: (view in full screen so that the code doesn't get jumbled)
import java.io.*; //Imports the Java library
class progB //Defines class
public static void main (String[] arguments) throws IOException
BufferedReader keyboard; //<-
InputStreamReader reader; // Allows the program to
reader = new InputStreamReader (System.in); // read the the keyboard
keyboard = new BufferedReader (reader); //<-
String name; //Assigns the name variable which will be parsed into...
int newnames; //...the integer variable for the amount of names.
int order = 0; //The integer variable that will be used to set the array size
String[] array; //Dynamic array (empty)
System.out.println (" How many names do you want to input?"); //This will get the number that will later define the array
name = keyboard.readLine ();
newnames = Integer.parseInt (name); // Converts the String into the Integer variable
array = new String [newnames]; //This defines the size of the array
DataInput Imp = new DataInputStream (System.in); //Allows data to be input into the array
String temp;
int length; //Defines the length of the array for a loop later on
for (order = 0 ; order < newnames ; order++) //<-
{ // Takes the inputed names and
System.out.println (" Please input name "); // gives them a number according to
temp = keyboard.readLine (); // the order they were inputed in
array [order] = temp; //<-
for (order = newnames - 1 ; order >= 0 ; order--) //<-
{ // Outputs the names in the reverse
System.out.print (" \n "); // order that they were inputed
System.out.println (" Name " + order + " is " + array [order]); //<-
for (order = 0 ; order < newnames ; order++) //<-
if (array [order].startsWith ("M") || array [order].startsWith ("m")) // Finds and outputs any and all
{ // names that begin with M or m
System.out.print (" \n "); //
System.out.println (array [order] + (" starts with M or m")); //
} //<-
for (order = 0 ; order < newnames ; order++) //<-
length = array [order].length (); //
if (length >= 5) // Finds and outputs names
{ // with 5 or more letters
System.out.print (" \n "); //
System.out.println ("Name " + array [order] + " have 5 or more letters "); //<-
}The notepad file contains the following names:
jim
laruie
tim
timothy
manny
joseph
matty
amanda
I have tried various methods but the one thing that really gets me is the fact that i can't find a way to connect the names to the arrays. Opening the file with FileInputStream is easy enough but using the names and then outputing them is quite hard. (unless i'm thinking too hard and there really is a simple method)By "connect", do you just mean you want to put the names into an array?
array[0] = "jim"
array[1] = "laruie"
and so on?
That shouldn't be difficult at all, provided you know how to open a file for reading, and how to read a line of text from it. You can just read the line of text, put it in the array position you want, until the file is exhausted. Then open a file for writing, loop through the array, and write a line.
What part of all that do you need help with? -
Populating an array of objects with a loop. Noob PHP question.
Hey guys,
You are all such a great help! Here is another one for you, the simple code below should create an array of pizza objects (and it does) then display each object in order. However... for some reason each object in the array seems to inherit the properties of whatever the last object entered was.
This code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<?php
class pizza{
public $price;
public $description;
public $name;
$menu2=fopen("pizzaMenu2.txt","r") or exit("System Error!");
$pizzas = array();
$arraypos=0;
//This loop does all of the READING and populating of variables
while(!feof($menu2))
//First get the array position
$arraypos = (int)fgets($menu2);
//Then Put in Title in title2 array
$pizzas[$arraypos2] = new pizza(0,0,0);
$pizzas[$arraypos2]->title = fgets($menu2);
$pizzas[$arraypos2]->description = fgets($menu2);
$pizzas[$arraypos2]->price = fgets($menu2);
} //End of reading loop
//begin writing data
$arraypos=1;
while ($arraypos <=3){
echo "the array is in position: ".$arraypos;
echo "<br />";
echo $pizzas[$arraypos2]->title;
echo "<br />";
echo $pizzas[$arraypos2]->description;
echo "<br />";
echo $pizzas[$arraypos2]->price;
echo "<br />";
$arraypos++;
}//end of writing data loop
fclose($menu2);
?>
<body>
</body>
</html>
returns this:
the array is in position: 1
Test Pizza Two
The same as one with an extra one, yum!
22.99
the array is in position: 2
Test Pizza Two
The same as one with an extra one, yum!
22.99
the array is in position: 3
Test Pizza Two
The same as one with an extra one, yum!
22.99
when it should return this:
the array is in position: 1
Test pizza One

11.99
the array is in position: 2
Test Pizza Two
The same as one with an extra one, yum!
22.99
the array is in position: 3
Test Threeza!
Do you see what I did there? I added a three to pizza, hahaha, I am so punny.

using the following text file pizzaMenu2.txt:

Test pizza One

Do you see what I did there? I added a three to pizza, hahaha, I am so punny.

22.99
Now, I have done line by line testing and shown that the values are being entered into the proper objects in the proper array, but whatever goes in last overwrites all of the other objects, so in the end I have 3 objects in my array that are all the same. I am not sure what I am missing here.Christ-Guard wrote:

If you have a good idea something should work, based on theory, then that's half the battle.

Problem: check random array with a static value
My goal is to use the random number generator to put numbers into randomArray, then do a linear search to try to find if the number 5 has been generatated. Next print out where in the array the value can be found. I have no compile errors but I have a logical or syntax problem, any help would be great.
public class test {
int j;
int target = 5;
public static void main(String [] args) {
int i;
int[] randomArray = new int[20];
for(i=0; i<randomArray.length; i++) {

System.out.println(p);
}Hi,
That's correct. You need to call the other methods just as you call display, but you do also have some other minor problems. You have written some methods that aren't needed, and they do nothing. This might help you:
public class test {
public static void main(String [] args) {
int i;
int[] randomArray = new int[20];
for(i=0; i<randomArray.length; i++) {
randomArray[i] = (int)(Math.floor(Math.random() * (10.0 - 0.0)) + 0.0);
test n = new test();
int indexFound = n.arraySearch(randomArray, 5);
n.display(indexFound );
public int arraySearch(int[] randomArray, int target) {
for (j=0; j<randomArray.length; j++) {
if (randomArray[j] == target) {
return j;
return -1;
public void display(int indexFound) {
System.out.println("Five is found in array position " + indexFound);

Plotting xyz Coordinates on 3D Graph Help
Hi,
I have an array (max size 10) of xyz coordinates which i want to plot on a 3D graph.
These 10 points are constantly moving (data from a Leap Motion hand tracker)
I have attached a screen shot of simple VI and example data
How would i go about gaphing this?Hi coqwas,
That's a pretty interesting project you have there.
I guess there is 2 types of 3D graph which you can find (use quick drop if you have to): 3D Line Graph and Active X 3D Curve Graph. You can find some examples on 3D graphs in NI Example Finder as well (Open LabVIEW >> Help >> Find Examples... >> Search key word "3D graph").
Since it is a 3D array, can you tell me the array size for X, Y and Z (e.g. X size by Y size by Z size)? What does the row and column represents in the XYZ array shown inyour screenshot?
To use the 3D Line Graph.vi, you'll need to provide a 1D array of X vector, Y vector and Z vector. So you need to extract the values from that XYZ 3D array to those vectors respectively. You can extract the Z layers using Array Subset and Reshape array. Since I'm not really sure which part of the array (X, Y or Z) represents the finger no., you'll need to separate each array by individual fingers. Each XYZ array for each finger is fed to each create_plot_line.vi (4 fingers meaning 4 create_plot_line.vi) just as shown below:
You can see there is a number from 0-3 at the create_plot_line.vi. Those are the plot ID (0 means plot 0 and 1 means plot 1). What I am trying to do above is that I'm ploting 4 plots in 1 3D graph.
The plot ID is specified by going to the front panel >> Right click on the 3D Line Graph >> select 3D Graph Properties >> go to Plots tab >> on the left column called Plots, add as many plots you want to plot into the 3D graph.

Learning new things everyday... -
I have found a script that allows me to create a scrolling
photo gallery for my site. The actionscript code that you modify
yourself has an array and you can just change the names of the
pictures to match your own to pull pictures into the movie. The
array is the picture names enclosed in quotation marks and
separated by commas.
I would love to load this info dynamically. I have a php page
that pulls all the pictures in a directory and publishes those.
http://www.stacybuckley.com/vars/pics.php
There are various ways (maybe not the best) that I can import
this data into flash but the quotation marks come out encoded and I
can't seem to "un*escape" them.
I could leave the quotation marks out of my php page, but
then when I reference the array position it doesn't see it as a
string and the script doesn't work.i don't see the loading method for the php doc in this code -
however you should be able to leave out the quotes and they should
come in as a string. If you are trying to pass this as an array,
that may also be part of the problem. you'd need to pass it as a
concatenated string and then use split at the commas on loading and
push them into the array, then they should come in as
strings.
