How to draw polyline which follows another polyline

[Fthnl]

Hi everyone;

 

I want to draw multiple polylines which starts different point but follows same path and end at same point. 

Is there any quick way to do this.

You could try using the MLINE command: https://help.autodesk.com/view/ACD/2023/ENU/?guid=GUID-A6839A41-0D81-44F2-953A-220307F9380A

 

Or just draw one polyline and then offset it to create the other lines.

I think i couldn't explain what i need. Ther will be approximately 500-1000 polyline in one project. 

Polylines are cable and the path is cable tray. Polylines end in same end point but they start different points and some points they will folow path to the end.

Maybe a lisp or some quicker method to draw polylines not one by one.

Yes, if you're talking about hundreds of polylines then you will probably need a lisp routine.

 

I have moved your question to the Autolisp section here: https://www.cadtutor.net/forum/forum/15-autolisp-visual-lisp-amp-dcl/

If I understand draw pline 3 1st using some smarts, then pick pline 2 start point, then done, pick pline start point 1, then done. 

 

You talk about hundreds so need a better dwg with plines for say 50 plines so get a better idea of what your trying to do.

This is a sample project which i need to draw polyline (red) which starts green and purple blocks right and left side and finish underside of all. all polyline will finish same location.

Just wondering, you arn't going to get hundred of cables side by side on a cable tray, they will be bunched together or stacked on top of each other (1000 cables at say 20mm diameter side by side gives a 20m wide cable tray.....). Which is what you show.

 

So in reality do you need to draw each cable along the complete route or just from the start point to where it joins the main cable route? This is the part you'd be doing manually anyway

Cable is 6mm dimater and cables will be bunched together in a tray. I will choose how tray will be in each direction by how much cable are in that direction. Thats why i need to draw all polyline so i can quickly count them.

draw the longest route,

copy it, and then trim it, use PLC route for continue draw exist polyline. (work end by space bar, not esc key)

If it is difficult to overlap, work by temporarily hiding it.
