Roof trim, Coord

Anonymous — Thu, 13 Jul 2023 14:32:48 GMT

Hi,

How could i get object edge/coord after Roof triming ? I was using API_Box3D extent3D.zMax for object.
This doesn't work with Roof trim. Even more because of sided roof object is higher than in other side.

Couldn't found approach to this yet.
Any ideas?

Is there at least a way to know if object have been trimed ?

Hmmm, i could get and calculate roof coordinates and therefore calculate trimmed area.
Will try to go this way...

Get the element memo data with ACAPI_Element_GetMemo. If the gable handle is non-zero (which contains details of the cutting planes) then the object is cut.

(memo.gables !=0)

You meant like this ? I guess i'm doing something wrong. Didn't understand how it works.

GSErrCode  ACAPI_Element_Trim_GetTrimmingElements ( 
        const API_Guid&         guid_Element, 
        GS::Array<API_Guid>*    guid_TrimmingElements 
    );

Found this function. As i understand this function return guid of element who have trimmed guid_Element. And will give needed result which i'm seeking. Although as i understand with API_Gable i could already get trimmed area with this function i would need to calculate it aferwards.
Buttt... It returns - Invalid value passed in the guid_Element parameter.
How can i assign API_Guid to const API_Guid& , it should be simple i guess ?
