I need to apply holes on a triangle polyline in Acad 2004, my issue is not to use the “measure” Function, but to apply the holes with the same individual distance, within the limits of max 200 mm and min 150 mm. Besides this I need a hole in all three corners.

I hope that you can help me find an easy solution to this problem.
I am also working in SketchUp, if anyone have a solution.
 
 Another issue is to place holes in a grid of 250x250 mm, within a triangle automatically. Is that possible at all?Abekatten2010-05-04 13:02:10

Use "divide" rather than "measure" to evenly space objects (circles/holes) along a line segment, with equal offsets from endpoints. You'd need to do that for each leg of the triangle separately. Based on leg length figure number of segments that give the required spacing
 
For a grid of holes you can use "Array" then erase objects outside the triangle.
