I’m thinking of a selection tool that could work similarly for object edges and also for curves. This would likely have to be two separate commands for them though. Select Object Edge By Length: First select the object(s) you want to perform the command on, then select either option (1) an edge (it would measure the length of) or option (2) input a length, and then it selects all edges with that common length. When specifying the length you could also optionally specify a range. Select Curves By Length Option (1) Select a curve (it would measure the length of) or option (2) input a length, and then it selects all curves with the common length. When Specifying the length you could also optionally specify a range.

Thanks Mitch! I will give this a try.

whoa! These scripts are so essential and powerful, they should be stardard commands. @pascal

Is there a script for sel arc by radius like your selcrvsbylength? I searched before my question but couln’t find it.

Yep, here are a couple… SelByRadius.py (2.8 KB) SelSameRadArcsCircles.py (3.0 KB) Note neither of these distinguishes between arcs and circles - I could modify either one to do so I suppose…

Thank you again, this works for me.

Thank you so much Helvetosaur! SelSameLenCrvs just saved me hours of work. I love it so much that I made a button for it.

+1 for making this a standard function. Very useful for cleaning up drawings from Make2D or imported from other softwares. If you know that lines under a certain length are not be visible at the scale of your drawing, culling them is a great way to optimise your work. Let’s say working on an axonometric, selecting all curves that are shorter than 1 mm and deleting them. Microstation has this function.

The following two scripts will cover your request #2… with a few additional bells and whistles. I may actually combine them into one.
