How I can attach ACCESSORIES object to walls by my own add-on?

Anonymous — Tue, 04 Oct 2022 14:29:21 GMT

The customer requires that the objects were hung on the walls entirely on the whole floor or selectively according to a given condition.
And when moving walls or openings, that objects must correctly rebuilt their contents.
The element based on the ACCESSORY object is best suited for this.
But you can hang it on the wall only through the menu "Wall accessories" and only by clicking the mouse.
How I can you assign an ACCESSORY object to the walls using your own add-on?

To understand your objective just a little better, what are the given conditions that determine where the objects/elements are to be located on the walls? Some distance from the end, centered between openings...?

Steve - This question is in the API developer forum... so I believe the questioner is asking how to create the live associate link in code...

Yes. But it could still be important to know what the given conditions are. I assume that the first step in making an Add-on is to model a examples of the intended results. Then sort of reverse engineer the code to generate them.

They could just use Cadimage Coverings – that's exactly what it does (also to roofs, slabs and columns). Or is there a broader objective?

I was also trying to attach an accessory to a wall. The first thing that I did was set the API_Element::object::owner to the wall guid. But it did not attach to the wall and the API_Element::object::owner becomes APINullGuid after the creation.

What info do I need so that the accessory will attach to wall?

---------------------------------------------------------------------------

EDIT: Also is there a way to automate adding Wall Accessory? I am thinking of a function that will accept: (a) the guid of the parent wall; (b) the libpart index of the wall accessory; and, (c) the side of the wall (inside/outside) to which the wall accessory will attach to. Simply put, its like (a) selecting the wall; (b) clicking on [Design] > [Design Extras] > [Accessories] > [Wall Accessories...] then selecting the libpart; and finally, selecting side ().
