drawing scale [SOLVED]

ReignBough — Tue, 01 Aug 2023 14:37:12 GMT

I am trying to add drawing using the API. I am able to do so but the scale of the drawing done with the API is not the same as manually doing it (drag-drop). (See attached image file.)

The first image (above) is done manually while the second image (below) is done using ACAPI_Element_Create() function.

I have already tried modifying the ratio value of the drawing element but it just zoomed the second image instead.

It seems like the API-generated drawing's scale is based on the original floor plan scale.

The attached picture is a screenshot of the lower-right of the floor plan and the same API-generated drawing. They are of the same scale.

Now, how to set this API-generated drawing to the same scale as the first post (the detail's scale) is still unknown [to me, at least].

EDIT
Is there a way to set the API_DrawingType.drawingScale (Drawing Scale in Properties) and/or API_DrawingType.parentOriginalScale (Original Scale in Properties) before creating the drawing element (ACAPI_Element_Create())?

I figured it out.

What I initially have done was create a drawing element using an item's GUID from Project Map (API_ProjectMap).

It is supposed to be from View Map (API_PublicViewMap).

I don't know the API, I am not a programmer, but the View Map makes sense as it stores the scale, while the Project Map always works with the currently active scale, which can give unintended results.
