I cannot use 2 Axes Constraints

[taskin]

When I try to align two axes and select the cylindrical surfaces, it used to automatically appear the three choices below on Constrain Window. But now they are disappeared and I couldn't figure out what the problem is. Any solution?

What version of Inventor (including updates) are you using?

Autodesk has been weaving and bobbing like a drunken sailor with that functionality over the last few 2019 updates..

Can you show an image of what you are trying to constrain/select and what you are seeing in the constraint dialog?

Make sure that you are on Mate rather than Flush in order to get those options.

 I am using Autodesk Inventor Professional 2019 Release 2019.3

I think the video below can tell my problem.

yep.. see response from JD.. switch your constraint solution type back to mate instead of flush..

Or install 2019.4
