How to constrain a series of connected lines

[Anonymous]

Hello,

So I'm working on a project for a club I'm in where I have an irregular polygon made of lines constrained by length and angles, however, the shape itself is not constrained. I am not sure how to constrain these lines, without losing the lock function, which I really do not want to use. I am using Autodesk Inventor 2019 Pro. Here is a screenshotScreenshot (18).png

Thanks.

Hello @Anonymous,

Welcome to Autodesk community!

In therory, it has at least one coordinate full contraint point, such as one of the point coincident to origin UCS' center point, then, add dimension or constraints later to make sure that every elements are well defined.

Please upload the file and forum experts can help on it.

Thanks!
