I dont know about length tho. Ideally, i would like to just draw lines on a layer, and then have SU sum up the lengths of all the lines on this specific layer. What would also be nice, if i could somehow highlight the all the lines on this layer, to visually check if i didnt forget any parts in the model. Anyone knows how to do this?

Regards,
Andy

If you look ½ way down this page http://sketchucation.com/forums/viewtopic.php?t=23991, TIG wrote me a script to add up hedge lengths from a separate line layer I was doing in the drawing - would that work for you?

Hi Andy,
I think it´s possible: right click - entity info - uncheck "cast shadow" box.

Thanks Gaieus, got it.

Hi Andy,

Create a 3rd layer for the top face of the ground floor walls. Now open that group, double click on the top face and copy it on the clipboard (Ctrl+C). While that top face+its bounding edges are still selected, right click and hide.
Now close the group and paste the copied top face in place (Edit menu). Make it a group, too, and set the visibility to be ONLY visible in Scene 1 (with groundfloor) while hidden in Scene 2 (with second floor, too).

Now open the second floor group, too, double click on its bottom face and hide that, too.

See attached file for ideas...
