Hello again. [IMG1] I have lots of these units with vairations and I need to extend both curve ends within a kind of shape ( here for this example, a rectangle). I tried extendcrv select rectangle as boundary object, and then select the curves as requested (selcrv), but none of the extension is d…

I hacked out a quickie script for you to try… ExtendCrvsBothEndsToBoundary.py (675 Bytes) Edit: Guess I didn’t necessarily need to limit it to just one brep for the boundary objects. ExtendCrvsBothEndsToBoundaryObjs.py (739 Bytes)

This is awesome! Thanks!:grinning_face:

[image] Helvetosaur: Guess I didn’t necessarily need to limit it to just one brep for the boundary objects. This is a great tool! But multiple boundary objects give inconsistent results: [image] Inner and outer box - curves extend to inner. Overlapping boxes - seemingly random extension t…

Yeah, figured as much, that’s why I limited it to one BREP in the first try. The second one should work fine for specific situations such as between just two boundary surfaces, but I was pretty sure Rhino wouldn’t necessarily be able to sort out more complex boundaries. FWIW

I shared it into the common topic here, because it’s too important to be missed. :slight_smile: [image] Share your favourite scripts, macros and plug-ins Rhino for Windows A great script by @Helvetosaur meant to extend one or multiple curves within a boundary.…

Hello Helvetosaur, I found that your script which were perfect are no longer workable after some automatic updates of rhino. After I perform the script, it will freeze all views and I need to restart Rhino.

Do you have I file I can test with?

Thanks for quick reply, and yes I should have the file prepared: Script display failure.3dm (130.5 KB) [02] This is how the views look like. They are freezed. I have to save the file immediately and restart Rhino. [01] Besides, I would like the shorter group of curve extend in straight line. Is…

Hi, I am not seeing a lockup here with the latest V8 Service Release Candidate - 8.25.25287.14001, 2025-10-14 Note the following - the script is currently set up to extend curves “smooth” - that is to say as if you used the Rhino command _Extend with the smooth option - it tries to extend NURBS cur…

Thanks for quick reply. Here is the video screen cap, i hope it can play here: And yes I noticed the crvend situation. It was a surface of STEP file from client, they are not expert in surface concepts. I love your script that can extend all isocurves, and I will try your new scripts tomorrow…

What version of Rhino are you running? When the freeze happens, if you type at the command line _SetRedrawOn and Enter - if you can’t get to the command line, just try typing it anyway - does the screen refresh and can you work? The script cuts the display redraw and I’m wondering if it is not get…
