Hi, I'm having a bit of trouble getting my polygon closed without changing the dimensions of the polygon.
The drawing attached or at http://img13.imageshack.us/img13/7494/drawingz.png you can see I've got a polygon.
However I do not know the radius of the angles A, B and C. I know that all the lines have to be the dimensions marked.
Can Autocad automatically bend the angle say, at A without changing the dimensions in order to complete the polygon? I tried this http://forums.augi.com/showthread.php?106618-Joini
Solved! Go to Solution.
Use Constraints and Parametric dimensions (see the Parameters tab).
see attached - drag the endpoint - is this what you want to do?
Add parametric angle dimensions for the angles you know.
Thankyou very much for the reply, I was able to reproduce this in my copy of AutoCad 2013 for MacOSX.
I see that for d1 3500 I see you set:
* Parametric > Dimensional Constraint > Horizontal
* Parametric > Geometric Constraints > Fix
For second line, d2 2320 I see you set:
* Parametric > Dimensional Constraint > Vertical
For d3, d4, and d5 it appears that you set:
* Parametric > Dimensional Constraint > Aligned
I also noticed the constraint between d2 & d3, d3 & d4, d4 & d5 you set:
* Parametric > Geometric Constraints > Coincident
However I realized that there's multiple pentagon shapes which have the same amount sides (5) with the same dimensions but different angles (other than the 90 degree angle). I must have been a bit tired when I asked this question, because that didn't occur to me, heh.
Constraining them only takes care of the lengths, I really need to take some measurements from my physical application.
I had the same error as LaserGuy mentioned there, but it seemed to be fixed when I added the coincident constraints and clicked on on the line rather than the endpoints. (At least that's what I think I did).

Thanks for the helpful answers to an Autocad newbie
My example was to show that you need to remove at least two of the contraints to close the geometry.
