dimensional constraints won't display

[Anonymous]

When trying to use geometric constraints, I might see one or two icons, but no more. AutoConstrain shows one Perpendicular icon for a rectangle. It would need Parallel (or Equal) and Coincident constraints to function  as is does but they don't show up.

The dimensional constraints  will not stay visible.  They will show only when I select objects but cannot be selected individually.  I have tried SHOW ALL/HIDE all from the tool bar and long hand.  Nothing seems to work.

Please post a sample drawing.

Maybe something in the settings window was disabled?

Attached is a screen cast and the drawing I was in at the time.

Set me straight!

Thanks

Look in your screencast sec 36-37: I'm missing a lot of checkmarks ;-).

(above I have already added this assumption while you posted this video).

OK, that was a dumb one.  I was looking at it as something similar to Osnap Dialog box.  

Now, what about the second half?  The

BTW: I guess (I'm no sure yet) there are some little differences between the plain (Vanilla) AutoCAD and AutoCAD Mechanical. Your drawing shows some strange effects, which i can't reproduce here.

Maybe you better ask in the Mechanical forum (?). Or you wait/hope until one of the Dynamic block gurus will answer here.

I'm not sure why the dimensional constraint visibility behaves the way it does in your file.  If you go to block editor and parameters manager then you can convert them to constraint parameters and they will display full time.

FWIW, I would not recommend mixing dynamic parameters/actions with dimensional constraints/constraint parameters like you have in your block.  They don't play well together.  Pick one or the other.  As a general rule, dynamic parameters/actions are easier to use, behave more consistently, and cause fewer issues so I would use those unless constraints are actually needed for accomplishing what you want.

Notwithstanding many other shortcomings in this block definition (paraxGLASS.dwg): My problem is a visibility mysterium.

First screencast (My own drawing): created a dimension and can turn ON and OFF its vilsibility as I want.

Second screencast (paraxGLASS): dimensions are not visible. After converting in Paramter and converting back to dimension I can see this dimension. But after I turn its visibility OFF, i can not turn back to ON again. (Only the same way: convert -> convert back -> visible.)

That's the strange behavior in this dwg, which I don't understand.

Any comments?

I don't know if this is how it came to be but it seems like a possibility.  It seems to give the same result.  You can do amazingly confusing things by deleting visibility parameters and leaving behind invisible items.  🙂

Shortcomings! Hah!  You got it!  I'm just messing around trying things out in this one.  But this is not the first time I've run into this.  It's been problematic since I "upgraded" to 2018.  Deleting visibility states might be one factor. I'd have to keep an eye on what I'm doing when I run into it.
