Unnecessary Columns Movement

HKM — Tue, 17 Sep 2024 11:10:20 GMT

Archicad26 / API Development Kit 26.3000 / Windows10
Use 'ACAPI_Element_Change()' on a column whose 'coreAnchor' is other than 4, it will be moved in parallel.
This can be confirmed with "Do_Change_ElemParameters()" in the SDK "Element_Test".
Is there a way to avoid this problem?

Confirmed the same problem with Archicad27.

Does anyone other than me have this problem?
Or am I misunderstanding something?
Any advice would be helpful.

Hi,

I'm not clear what the problem you mentioned. When you try to modify a column coreAnchor=4 to coreAnchor=6, it means the left bottom corner of column will be moved to the position of the center of colmun because you didn't change the origoPos.

Let me explain the procedure.
1. Draw a column.
2. In the column settings(ctrl+T), change the anchor to something other than the center.
3. Execute "Do_Change_ElemParameters()" in the SDK "Element_Test" on the column.
4. The column will move.
(If the column anchor is at the center it not move.)

Sorry I couldn't reproduce this issue following your steps, I'd suggest you update AC27 to the latest release(27.2.1) and try again.

This issue occurs even in the latest environment.

I see, I've asked our API developer to check whether it's an bug issue. As a workaround, I'd suggest you to shift origoPos to anchor point before calling ACAPI_Element_Change() if the anchor is not 4 in this case.

For example:

ACAPI_ELEMENT_MASK_SET(mask, API_ColumnType, origoPos); element.column.origoPos.x (+-) = half of column width; element.column.origoPos.y (+-) = half of column depth; err = ACAPI_Element_Change();

HTH.

Thank you for providing the workaround.
Hopefully this issue will be resolved in Archicad 28.
