What I don't understand is this. Does that mean I have to redo all the dimension lines in Core Only?

The dimension in the Entire Model is gone in Core Only.
Even with Ctrl+C and V, I couldn't send the dimension to Core Only.

Hi,

yes it does 😀

[Barry Kelly]

Yes.

Each Partial Structure Display must be dimensioned separately.

In one you might want to dimension the entire width of a wall including the finishes.

In another you won't be showing the finishes, so there is nothing to associate the dimension to any more.

Hence you need to place new dimensions for each Partial Structure Display.

Barry.

How should I place it?
I have to redraw it manually.
I think it is wrong.
Shouldn't it be possible to copy to the same element as the window OPEN dimension?

Do I need to develop an API in C++?

of you want it to function different, then yes

(yet) another oportunity for more automation

Sorry. If you write a little longer, I think it will be easier for me to understand.
I have to use translate.google.com. ^^

You can use automatic Dimensioning for interior and exterior dimensions, so easy operations with just 3 clicks.

Sorry LeeJae, cant help on this one. Buy you have already been provided with a solution, albeit not the solution you wanted. 

My comment was just a rethoric lament on the current state of things.
