TAKEOFF PIPE OF DIFFERENT SIZES

[ababs]

Hello everyone,

I’m trying to create a LISP to help with pipe takeoffs in AutoCAD. Here’s what I want it to do:

I have a plan with pipes of different sizes drawn as lines or polylines.

I want to create a takeoff layer (e.g., "M-TakeOff-CWS").

Instead of redrawing, I just select a line or polyline segment and choose a pipe size.

The code should automatically split the selected segment at all intersections with other lines or polylines.

Each resulting sub-segment is duplicated in place on the takeoff layer.

The duplicated segments get a color based on the chosen size.

The original line or polyline stays intact.

Later, I want to filter by color/size to calculate total lengths.

I’ve tried several approaches, but I’m struggling with:

Splitting segments automatically at intersections.

Duplicating them on a new layer.

Assigning colors by size.

Does anyone have a simple LISP example or guidance for this workflow?

Thanks in advance!

Can you upload an example *.dwg file please to see how we can help.

Welcome aboard.

 

Yes need a sample dwg showing a before and after, breaking at intersections various examples are out there.

 

When asking for help you nearly always should provide a sample dwg or some images.

i need  to duplicate the original layer and for each size assign  a color 
instead of redrawing them manually

I would just have a menu to pick what type then loop a polyline picking points. creating the polyline on that layer with the color code maybe a thickness as well. and have the ability to switch type.

Have a close look at my Water Supply program which should facilitate your work significantly.

Trial version is outdated now.
