Thanks for the reply, but I'm afraid it wasn't quite what I was looking for.
I'll try to explain somewhat better:

I'm modelling a façade.
The façade follows an irregular shaped curving path.
It consists of three different types of boards.
At random intervals there's boards missing, leaving holes.
Due to the size of the building, each board when arrayed uniformly along the path counts to about 1500. Because of this I was hoping to find a tool that would delete random objects from a selection set. Being able to adjust the randomness would be a plus.

Can you imagin an architecture firm where a bunch of people are talking to their PC while modeling?....

Yes I can. I'm one of them people. And that's without any voice activation software.

Is there a plugin that deletes random object of the current selection? I've been searching for one, but haven't found any.

The reason is that I'm modelling a large surface where objects are placed at irregular intervals. I was thinking that I'd array copy them uniformly and then randomly delete them. However the objects are about 1500 once placed uniformly so I had hoped there's be an automated way as oppose to do it manually.

hehe, as I don't mutter enough when I work

If no other lines or faces touches your lines you can double click the line in Select mode and it should select all connected lines. (Also any surface bound inside your lines if there is any.)

heh! Never noticed the Divide menu item. Thanks.

btw, is there a way to merge lines that's been broken up?

I think you draw a line at the beginning of the surface you want to divide, then copy that to the other end of the surface, then you immediately afterwards before doing any other commands type "/10" if you want to split it into 10 equal parts.
I think that's how it was.

To extrude a face multiple times just type "*10" afterwards.

Never mind. Just realised that Ctrl did the trick.

Is there a way to make the extrude tool not merge the faces of the original shape with the extruded part?

Example: Extruding a square four times and afterward have lines cutting through the face at each interval done.

Ok, I just realised something about the behaviour.

When I rotate the viewport it centres around the object the cursor is over. If the cursor is not over any objects it uses the scene's 0 point.

I'm still wondering if there's a way to lock the viewport rotation centre point. When I'm modelling objects with not allot of surface, such as a fence, it consumes more time to aim the cursor at a small piece of surface. I'd much rather be able to lock it so I can press down the middle mouse button anywhere on the screen to rotate around the object.

When I edit a component and rotate the viewport it often rotates around a centre-point far outside my component area causing my component to fly far out of view. Double clicking the middle mouse button centres it, but it often laps back again while I'm editing.

Any remedy for this? Very annoying to constantly having to relocate the component every time I want to rotate the view around it.

Also, sometimes the Zoom get stuck. It barely zooms in or out. Most noticeable when using the mousewheel. Slighlty rotating the viewport sometimes helps a bit.

No Point at center here either. SUP6.

I use the endpoint inference trick, but when there's many object near or around it it often doesn't want to lock on the centerpoint. No way to further encourage it?

o_O

Mange takk!

Thanks!
Works well with the Filter plugin that quickly let me filter out just the faces.

But yea, it'd be nice to see stats for a selection of object.

Is there a way to see the polygon count of the current selection?

I'm working on a file with a total of about 200000 edges and 45000 faces when I count nested components. I didn't create the file initially and I'm now trying to locate meshes with unnecessary high poly count.

Have you tried with older drivers? Sometimes new drivers brake stuff that worked before.

Does the problem only occur in SketchUp, or in other programs as well?

That's very interesting. I think I'll have to have a little google session on Japanese joinery.

Got it working as I want now. Thanks again for your help.

Just what I needed! Thank you very much!

Is there a way to set where it begins the first object?
...maybe I can just break the spline..? I need to play around with this.

Thanks for your responses. Sorry that I wasn't very specific with my question, but I was referring to copy along an irregular edge. I was aware of the linear array copy.

I tried the ruby plugin, however I can't get it to work as I expect. The path is a set of connected lines, but the plugin won't let me select all the elements when it asks me to pick a path. It only uses the first segment I click on. preselecting the path doesn't do it either. Grouping the path segments is also a no go. Are they meant to be joined somehow? I've not found any command in SU to join connecting lines.
Any ideas?
