Intersecting lines

Hi, I am the greenest newbie alive. I am drawing with the pen tool (grrrrr not able to master) and when I have intersecting lines such as 2 s shaped curves the mid point has a gap so that it looks like someone erased part of one line. I am using 25 pt round brush. Also this is in CS 5.5 I have tried to highlight all the lines at once looking for some tool to change this and no luck I searched google for lines intersecting and gaps and nothing seems to fir my problem. Any help would be appreciate. Loving Illustrator so far.

I create name plaques using TypeStyler, but my laser cutter says they must be converted into two vector files; a cut file to cut the outlines of all the letters and an "etch" to etch the letter intersect lines. Can AI convert my TypeStyler file into a cut file and an etch file?

Thanks. I might use it soon...
Does it automatically make folders named after the volume labels? And does it handle the conversion of spaces and non-alphanumeric characters to octal codes?
I could read the script but it would be faster for everyone reading, if you leave the answer as a reply.
I also think that there should be some major work done on modernizing the fstab, either by replacing it with a better implementation of file system mounting or changing the file structure and adding in better handling of non-alphanumerics. I don't want to have to look up a stupid octal table every time I type in my labels.

How to find the intersecting lines

Hi All,
Can anyone tell me how to do this,
I am selecting lines passing thourgh point P1(x1,y1) and
another query select lines passing through point P2(x2,y2)
Now I want to find the intersecting lines from the above result.
Thank you
Anju

Hi,
If I understood what you mean, just do the following:
use your 2 queries as inline views (i.e. put them in the from
clause of your query), and join them asking for the intersect of
the 2 returned objects

Computing polygons from intersecting lines

I have a bounding rectangle that a user can add lines onto. The lines will always extend to intersect the rectangle, so a new shape is always created. Does anyone have any ideas how I would traverse the lines and intersection points to create the bounded polygons created as each new line is added? I need to be able to color each piece of the created polygon differently.
Currently I create lines and intersections which I associated with each other. I then tried traversing all intersections on line switching to the intersecting line at each intersection point. I compare the distance to the origin to determine the best point to chose on the intersecting line, but this is problematic. Is there an easier way to do this?

I figured it out. You essentially have to keep
Split the lines into segments
Iterate through the list of segments
Track of the origin point
Determine if a candidate point crosses any other line.
etc.

How can I calculate the area bounded by a large number of intersecting lines displayed on a graph?

Can I adapt 'particle (or blob) analysis' to a graph, or would I be better off saving my graph as an image and using IMAQ VI's to do particle analysis on the image?

Almost wish they some sort of a whiteboard feature on this forum. 'Cause this would be easiest to explain with some dynamic pictures.
Any way, to calculate the area "shared" by two or more functions you subtract the areas. Piecewise: calculate the area of fuction 1 by integrating over range of intersection, calculate the area of fuction 2 by integrating over range of intersection, subtract Area 1 from Area 2 and take the absolute value.
If more than 2 functions, start with the two functions with the greatest area of overlap, and work towards the smallest.
This is assuming continuous polynomial functions comprise the intersections and you know the points of intersection. If they are simple linear functions you might be able to do some geometric additions (a
dd up all the trapizoidal/triangle areas formed by consecutive points of intersection).
This is the robust works-for-most-cases solution, your particular instance may provide short cuts, but no details were given that might provide clues to those short cuts.
Good luck.

Help! Intersecting lines and cleanup question

Hi there,
I am brand new Illustrator CS5 user. I drew this image using the pen tool in Photoshop, and then I exported the paths from Photoshop into Illustrator.
I have a picture that looks like this, currently. The things I want to change are circled in red. They are the jagged protrustion on the two flag tags, and the overlaping lines.
I want it to look like this (edited using eraser in Photoshop):
How do I get from point A to point B in Illustrator? I've tried various solutions without success.
Your advice is very much appreciated!!

hoppingbean,
The flag edge with the zig zag should be a closed path with a fill, and each of the tags should be a continuous single path reaching or going underneath the flag edge (you may close them).
The pole should be beneath the flag edge and the tags.
You may see the stacking order in the Layers palette/panel.
I hope this is enough: three quarters after midnight here, time to attend to other duties.

I have Illustrator cs6 - missing intersect lines I think they are called

Previously, when I moved one shape around the area of another shape, I would see lines telling me that the two shapes were lining up. This was great but it's gone. How do I turn it back on?? Thanks in advance

Turn on Smart guides (View menu)
If you still don't see the guides you're looking for, go into the preferences and check the options

Anchor Points and Intersect Guide Lines Disappeared

Hi! I must have hit some type of command on my keyboard but now my anchor points and intersect guides have disappeared that would normally appear when I roll my mouse over the anchor point or the intersecting paths. I have hit Ctrl + H as well as went to the menu manually and my edges are showing. How do I turn back on this ability to see my anchor points and intersecting lines guide in Illustrator?
Thanks in advance!!
Edit: I run on Adobe Illustrator CS5

Is View > Smart Guides turned on? If not, enable it.
If Smart Guides are already turned on, check if Align to Grid is enabled in the View menu and turn it off.

Find lines intersection

Hi,
what is the easiest way to find lines are intersection in one table. I tried sdo_relate/sdo_geom.sdo_relate and didn't succeed!
Thanks
Al

Thank you very much for your response.
Sdo_join require a lot of pre parameters,
any idea what i m doing wrong in the following, i m getting wrong result for intersecting lines
SELECT a11.id, SDO_RELATE(a11.geometry, a22.geometry, 'mask=ANYINTERACT') as RelateResult FROM a_table a11, a_table a22
WHERE a11.id < 5 and (a22.id >6 or a22.id <8)
and a11.id =a22.id
order by A11.id
your help is appreciated!

Little problem with Shape.intersects

I have the following code:
boolean isCollision = island.contains(line.getP1()) ||
island.contains(line.getP2()) ||
island.intersects(line.getP1(), line.getP2(), 1, 1);This doesn't work:
The method intersects(double, double, double, double) in the type Shape is not applicable for the arguments (Point2D, Point2D, int, int)
Interface java.awt.Shape:
intersects(double x, double y, double w, double h)
Tests if the interior of the Shape intersects the interior of a specified rectangular area.
Now I changed my code to the following:
boolean isCollision = island.contains(line.getP1()) ||
island.contains(line.getP2()) ||
island.intersects(line.getP1().getX(), line.getP1().getY(), 1, 1) &&
island.intersects(line.getP2().getX(), line.getP2().getY(), 1, 1);However, it doesn't seem to work since I don't get a "true" if there is an intersection; the "contains" method works excellent.
How can I intersect a line with a shape to see whether there is an intersection?
Thanks!

I am sorry, I am unsure in which forum my question fits best. Can an admin delete my posting from the wrong forum?
I would really appreciate help on this topic since I can't solve this problem alone :(

Is Illustrator CC's Smart Guides Intersect label MIA?

I recently upgraded from Illustrator CS5 to the latest Illustrator CC version and I noticed that Smart Guides no longer label intersecting lines... Is there a preference I need to enable for that label to appear as it did on CS5?

It's a tweak to put the ruler origin in Illustrator back the way it was before Adobe changed in CS4.
Example:
In pre-CS5 if you wanted to move an object dimensionally up and the right 1 inch you would select the item, double click on the black arrow tool and and in the Move window you would type "Horizontal 1, Vertical 1" and it would move up and to the right 1 inch. But, in CS5 Illustrator was change from using quadrant 1 to quadrant 4 (similar to how Indesign is) so if you wanted to move the same object up and to the right 1 you would need to enter "Horizontal 1, Vertical -1".
Which means you would always be working in negative space. If you're new to Illustrator you wouldn't even notice this but for "Veterans" this was a bit of pain... so someone out there was cleaver enough to figure out to "tweak" how the ruler interprets the origin and restore Illustrator to use quadrant 1.
The tweak isn't very difficult, but I would not recommend this to novice users:
How to change the ruler origin in Illustrator.
To change the ruler origin (and direction of the Y axis) in CC to be the same as in CS4 and earlier:
Close down Illustrator (you can only change the preference file with Illustrator closed);
This is a global change so you only have to do it once (just as you can undo it once).
Pref file directory is as follows (please note the Library may be hidden):
/Users/<username>/Library/Preferences/Adobe Illustrator Settings/en_US/1
Find and open the Adobe Illustrator Prefs file with Textedit
Find and change the following two bits of code:
/isRulerOriginTopLeft 1 change it to /isRulerOriginTopLeft 0
/isRulerIn4thQuad 1 change it to /isRulerIn4thQuad 0
Close and save the Pref file.
I only use Illustrator 1n OSX so I don't know where the Pref file is stored on Windows. I did not figure this out and I do not take any credit for this tweak. ***Mod at your OWN RISK***

How to remove cells interection line in JTable

Hello
I am new to Java Programming
I am facing a problem which i did not know how to solve so i need help from experts of this forum
I have JTable of lets say 5 columns and from that i want to hide some columsn e.g i want to get only column 0(or ist column) and column 5(5th column) visible to me and not the inbetween columns(i.e 2,3,4) so i coded it like this:
for(int count=0;count< ConnectedDrivestable.getColumnCount();count++)
               tcm = ConnectedDrivestable.getColumnModel();
               cm=tcm.getColumn(count);
              if( count==0 || count==4)
                   cm.setPreferredWidth(15);
               cm.setMinWidth(0);
                   cm.setMaxWidth(15);
              else {
                   //ConnectedDrivestable.removeColumn(cm);
                       //ConnectedDrivestable.removeColumn(tcm.getColumn(count));
                   cm.setPreferredWidth(0);
               cm.setMinWidth(0);
                   cm.setMaxWidth(0);
          }where ConnectedDrivestable is my JTable of lets say 5 rows and 5 columns
tcm is TableColumnModel and cm is TableColumn object
But the problem is that i am getting vertical line in between and that is the intersection line of column 1 and column 5(i.e the intersection line of two columns that are visible) i dont want this in between vertical line to appear
I really dont know how to fix this problem i have searched on internet but unable to find the appropriate solution to it
Also as shown in my code i tried to work with removeColumn method which documentation says should remove the desired columns but i dont know why it is not functioing for my case the way i acpected am i doing something wrong or?
So urgent help from people here is required
Thanks in advance

Hello
Thanks for reply and thanks for help
Do please tell me that i am rendering cells of JTable with JLabel it is working fine but i want to span JLabel onto multicells in the same row
Second i want to change the size of JLabel so that if not needed JLabel did not cover the whole Cell
A bit of code which i am using to do cel rendering is attched for your kind considerations
ConnectedDrivestable.getColumnModel().getColumn(1).setCellRenderer((new DefaultTableCellRenderer ()
               public Component getTableCellRendererComponent(JTable table, Object value,
                         boolean isSelected,
                         boolean hasFocus,
                         int row, int column)
                    JLabel Jlbl=new JLabel();
                    if(row==2)
                         ((JComponent)Jlbl).setOpaque(true); //if comp is a JLabel:Necessary
                         //Jlbl.setBorder(BorderFactory.createLineBorder(Color.BLACK));
                         Jlbl.setBackground(Color.GREEN);
                         Jlbl.setLocation(row,column);
                         System.out.print("The Column number is : "+column);
                         System.out.print("The answer is: "+ column+2);
                         ((JComponent)Jlbl).setMinimumSize(new Dimension(1,1));
                         ((JComponent)Jlbl).setMaximumSize(new Dimension(0,0));
                    return Jlbl;
                    //return comp;
          }));Another piece of code which i got from internet for doing the same is
ConnectedDrivestable.getColumnModel().getColumn(2).setCellRenderer((new DefaultTableCellRenderer ()
               public Component getTableCellRendererComponent(JTable table, Object value,
                         boolean isSelected,
                         boolean hasFocus,
                         int row, int column)
                    Component comp = super.getTableCellRendererComponent
                         (table, value, isSelected, hasFocus, row, column);
                    //((JComponent)comp).setBorder(new LineBorder(Color.BLACK));
                    if(row==2 && column==2)
                         //((JComponent)comp).setBorder(new LineBorder(Color.BLACK));
                         comp.setBackground(Color.GREEN);
                         ((JComponent)comp).setMinimumSize(new Dimension(1,1));
                         ((JComponent)comp).setMaximumSize(new Dimension(1,1));
                    else
                         comp.setBackground(Color.white);
                    return comp;
          }));These both work but as i tried to change the size of JLabel in the Cells it did not work also if i wanted to span JLabels to multiple cells(Column) is it not working
Also as in code snippet i am trying to set the border which works fine but what i want is that after spanning JLabel to multiple cells then i want border along this how to do this help in this regard too?might if i could span JLabel to diffrent columns might i able to set border aroung them too
I am putting under old forum topic this question as it is realted to my same problem so do please apologize me.
I do need urgent help in this regard so kind help is needed

Illustrator CC2014 does snap the Cut tool to path intersections w/ Smart Guides on

This is driving me crazy. Is there something I'm overlooking here or is this (essential) feature missing in CC2014?

Hey Jacob,
This applies to all paths.
You can try it for yourself - just draw two intersecting lines with the Line Segment tool, turn on smart guides, and try to snap Cut to the intersection.
This is kind of driving me crazy because it means to cut lines / objects exactly, I have to draw another shape, snap an anchor to the intersection (at least this works), send it to the back and then snap the Cut tool to the new anchor.

Line animation

I want to show intersection lines by making the line appear from left or from top from small portion to the whole line. I can do this by 2 ways:
1) Cutting the line into small portion on each frame. When playhead moving from first frame to the last frame, the line showing from small portion to bigger portion and lastly the whole line. This is very tedious if I have thousands of intersection lines.
2) By mask. Showing the mask part from small portion to the whole line.
My question : Is there a short cut ? or faster way to do this ?

are these all straight lines? if yes, then it's easy to do with actionscript.

Using a Mac Pro, how do I play only one playlist and use shuffle?

How do I play a specific playlist in itunes and use shuffle?

Go to the playlist. You'll see the intersected lines (shown below). Click on that and press play.
