Create parametric GDL pipe

phlp — Mon, 20 Apr 2026 05:15:05 GMT

Hello, I'm a newbie to GDL, trying to get into scripting / creating parametric objects.

Is there an easy way to edit the script of an object like a pipe to easily extend it?

Most importantly for a simple 2D-object.

Second, if possible, for a 3D-object. I'm currently using the shell tool to create it.

Cheers, phlp

You would just relate the element that is making the straight bit to your ZZYZX value. So for 2D that would be the y value of your LINE2 or POLY2 command while for 3D this would be your be your ZZYZX value in like your SHELL or TUBE.

~~LINE2 0, 0, 0, [fixed pipe length] - [pipe end length]~~
LINE2 0, 0, 0, ZZYZX - [pipe end length]

Ling.

ps. This is in the wrong sub, there is a specific GDL sub. A mod will probably move this for you.

pss. If the pipe was originally made via Save-as-object, then it will not be so easy as identifying parts in the automatically generated script so that you can isolate what you want to stretch from what you want to be static is difficult.

i created this object in about 5 minutes , using Gemini , you can set the lentgh with hotspots , and define the pipe inclination in the object parameters ,

Thank you for the responses and sorry for catching up late.
I've been trying using ChatGPT, Gemini and Google Studio but the results have never turned out flawless. Either the script had errors or it wasn't but there hasn't been any option to extend the pipe. Although I was very excited upon seeing your video, Heimo, I couldn't make any progress with AI, unfortunately.
