Hi Michael.

Yes, as an extra trim command option that could/would be extremely useful/welcome.

There will be a time when I use curves more but for now I'm very much on straight lines!

MoI of course is really powerful on curves, and surfacing using curves but it slightly lacks in the more boring (!) straight line department which is a bit of a shame.
I think I just hung on with SketchUp for too long, after (industrial engineering design) training using Solidworks/Pro-Engineer both of which weren't then as hot on surfacing. I don't know what either latter are like now as I haven't used either in so long.

But often when drawing or designing enclosures, bot small box-sized, or much bigger house-sized projects (I've done loft conversion projects for architects requiring modelled examples to show to clients etc), being able to split a line into equal sections is very useful.

I hope that makes sense.

Tom
