How to identify "dimensions needed" to have a fully constrained sketch?

[jeffrey.s.barrero]

Good morning

      Is there a way to have Inventor suggest, point, highlight, etc, the "dimensions needed" to have a fully constrained sketch?

I keep trying to apply more dimensions, but I keep getting a "Adding this dimension will over-constrain the sketch. Choose Accept to create a driven dimension"; even if I accept the driven dimension, it still shows 2 dimensions needed.

Any advice to avoid running in to this issue will be greatly appreciate it, and if I have to completely change the my approach to sketching; will be happy to.

Thank you for taking the time to read my post, and wish you a great day

Project the origin center point if it is not already.

Constrain a point on your sketch to that.

If all else fails, use the auto-dimension to help you figure out what is under-constrained.

As @john.retzlaff suggested, the Automatic Dimension and Constraint command can be used.  The problem with this tool is that it will place dimensions poorly or give a solution you do not want.  I would recommend to only use this tool to give you a hint as to what dimensions are missing.  Watch the screencast, I try to explain it.

Thank you so much, for your time and effort to answer my question. I have to say, that I am baffled of how much the features in this forum have evolve since 4 years ago; I also stumble my way thru and struggle getting around. I will make an effort now and familiarize my self, so that I may contribute back to the community as you fine gentlemen.

Thank you very much and wish you a great day.

It may not need dimensions, as well as the previous suggestions & assuming your sketch is symmetrical, you could make the angled lines equal to each other. Same with the 2 vertical lines.
