Hey all,

I was looking for a geometric construction to divide a line into N equal segments. Not that I cannot measure it, but I find that it always comes out a little more accurate when I use a geometric construction technique to get the answer.

Math Open Reference

Since we as woodworkers deal with a lot of geometric problems, I thought I would post this as it might be really useful to a lot of us. The table of contents for geometric construction is this link.

Math Open Reference:Geometric Constructions TOC

One good thing about this is that it shows an animated version of the construction so you can see it being done. Should work wonders in the shop.

Hope this helps other as much as it has helped me just today.

Great links! AutoCAD does most of the thinking for me.

I let Sketchup do most of my thinking also. But there are times when things do not turn out exactly like the drawing tells me they should. That is when I find things like this handy.

One thing I have always done is to be sure I do not size something (i.e. a drawer front) until the piece it is fitting in to (the face frame) is completed. Sometimes this produces a situation that I need to respond to without a CAD drawing. It’s not that I cannot do the math that I need to do, it is just that I find, at least for myself, in the shop, the geometric constructions are a lot easier, and end up being far more accurate than the measuring.

Glad everyone so far has found this useful.
