LibreCAD squiggle trimming?

[Sunset Machine]

I've a solid bar drawn and want to trim the ends with a squiggle to show that the bar is only a part of a larger structure. So I draw the squiggle and go into Trim. It says select a limiter, I select the squiggle , and then to trim. Nothing happens. LibreCAD

Any ideas? Kind of what I'm after:

Here's the rest. The vertical black bar.

Could you post the CAD file?

I've realized why. The black bar is actually 4 sides that I filled in with a hash. It's not a solid black bar, it just looks that way. I painted myself into a corner.

I think you'll need to draw the squiggly lines and then do the fill. But I'm not very familiar with LibreCAD. I use Solid Edge 2D and it has a built in function for creating the squiggly lines, and other types of break lines, for that type of scenario.

The obvious solution! I'm learning. Thanks Ed.

What's a spline? I keep seeing that term.

I assume you aren't talking about a shaft spline. I think you already know what that is.

So if you're talking about a spline in relation to CAD, then this link should explain it.

Hope this helps.

Of course - splines are nurbs. I should have known.

I'll have to read more - biggest question is why don't they call them "curves"? I'd guess it's because they are dots and not connected as far as LibreCAD knows.

Did I already warn you that this was my first CAD project? Clueless. Sometimes feel like I left the house without my pants. But I just go back and put them on. CAD has been a huge help, I'm glad I tackled it.

As to the original problem, LibreCAD can't use a nurb (!) as a limiter or trim and they basically are a stick in the mud. I changed my hatch so I don't mistake it for a line again, the ends are still square.

A screw thread is out of the picture too. No zig-zag lines that I have found yet.
Looks like multiple types of dashed lines will have to do. Now I have to lookup what a "block" is...

And thanks again for this:

I'm following LibreCAD by way of this guy:

I hope those links are correct.

I downloaded LibreCAD again yesterday and played around with it a bit. Ugh, after using Solid Edge 2D for so long, it's real painful to go to a less powerful CAD program.

Are you running Linux? If you're running Windows and have just started CAD I'd suggest you give Solid Edge 2D a try. It's free.

Solid Edge 2D

Just a suggestion.

Linux, yes. Gave up on MS twenty years ago. As for LibreCAD... My ignorance of the others probably helps keep the frustration level down.

LibreCAD is several steps above paperCAD though. I made some gears for this box the other day, one tooth short and a half-DP larger from the original. The darn things dropped right into place first try. Without the CAD it would have been far more difficult. Welcome to the 21st century Jimbo, where'ya been?

The carbide challenge lies ahead.... I'm about 40 years behind the times on that too.
