Dim Errors in Inventor 2017?

[The_Angry_Elf]

I ran across this just now and wondered what the heck could be going on.

I inquired to my guys about this and they said basically "Yeah, we've seen that before, we just over ride the dimension".

Notice the two different dimensions.

This is of the exact same assembly file, but done on two different drawings (same drawing template).

No settings have been changed.

Also let me add all updates are current.

Probably the "projected" vs "true" dimension settings..

Right click on a view and go to.."general dimension type" flyout and see if that fixes it..

The view could also be slightly off axis too

To me it sounds like one template has it set to 1/16 and the other as 1/4 under dimensional styles

But only assuming at this point and that I would assume you had already check that... 

Also the end points of the dimension are the same?

[mcgyvr]

^^ yep.. or that..

Thats' the first thing I checked. The ones you see in the pics are of the same template, same view and same model.

Everything I can think of checking has been checked, seems to be more random than anything hard to point to.

I'll keep looking into this, I'm sure it's some silly setting.

I will also assume since you blurred out some of the drawing view..  You're unable to share the information, correct?

I "think" I may have found the issue.

It seems it might be a constraining issue. In short, there's a "washer" assembly holding down the angled item on the top.

One of those washers was .009" below the surface of where it should be. The item on top is the one thing that changes (thickness) and thus if the user constrains that item to the offending washer (in this case 1 out of 12 to choose from), that seems to be the difference maker here.

Still need to verify this thought on a few other older jobs that used this same base assembly.

Oh yeah....they didn't even want me posting that...lol
