Acapi_get_elemlist sometimes return 0 elements??

Anonymous — Wed, 15 Sep 2021 09:52:03 GMT

Hello

I have a really weird bug.
I am using acapi_element_getelemlist. I am trying to get all the elements that has 3D representation and that are on visible layers.
So the command is:
ACAPI_Element_GetElemList(API_ZombieElemID, APIFilt_In3D | API_Filt_OnVisLayer);

Sometimes my elemlist gets 0 items! When of course my scene is full of elements!
I didn’t yet realize why this is happening but I think it happens when calling this command after the user created a new layout, or calling this command after the file was opened (before doing anything to the scene)

This is really weird.

Thanks in advance!

What kind of view is active when you call ACAPI_Element_GetElemList, e.g. floor plan, section, 3D?

Hmm, on most tests I was on layout view.

Try making the floor plan database active with APIDb_ChangeCurrentDatabaseID first, and then try ACAPI_Element_GetElemList.

Thanks. It’s weird that this function works just in this type of active dB..
At least that solves it
