Hello,
Have someone come across a use to set the height of an Object from code. Have added the screenshot of the field which I meant .
There are fields in API_ObjectType for setting the X and Y values but not for the height.
Solved! Go to Solution.

No you don't have to edit the library object itself. You have to change the parameters value for a specific object (which has reference to the relevant library object). The parameters for a specific object are part of the Element Memo of that object.
This way you can change single instances.

It depends on what you want to achieve. Editing the library part is rarely needed. Usually placed instances need to be updated.
You can use the ACAPI_Element_Get and ACAPI_Element_GetMemo functions to retrieve parameters.
In the API_ElementMemo structure there is the "params" array, that need to be updated.
If you install the devkit there should be an examples folder which uses these structures quite a lot. There is the Element_Test sample, and for example the Element_Modify_ChangeParameters.cpp in the project. There you can find ways to iterate through the parameters of an object instance.

Hi Kency, I think you need to change the ZZYZX parameter of the object. But don't have time to confirm right now.

Yep A, B, ZZYZX sets the dimensions of an object. ZZYZX is the height.
(But in case of a door for example A, B defines the hole in the wall.)

To edit the ZZYZX value, we would need to update the library object right? Will editing that affect the all the object instances or just a single instance?

Thank you this worked.
