How to Get DlantAngle／SlantDirectionAngle And endPos from Object on ACAPI

[nishida_jp]

In Archicad25
The rotation of an object (column/beam) on the XY plane can be obtained using "angle", but how do you obtain "slantAnge" and "slantDirectionAngle"?

Also, the starting point is "pos", but how do you obtain the coordinates that correspond to "endPos" in the case of a beam?

Hi.

You can get the element properties through the element type structures as shown below.

element.column.slantAngle
element.column.slantDirectionAngle

The help files installed in the following locations will help you.

C:\Program Files\GRAPHISOFT\API Development Kit 24.3009\Documentation\MSDN\APIDevKit

The start and end points of beams can be obtained using begC and begE properties.

element.beam.begC
element.beam.begE

Thank you．

But I need DlantAngle／SlantDirectionAngle And endPos from Element of Object.
I know column/beam.
Element(API_ObjectID) have [pos] and [angle] and memo.param[A],[B],[ZZYZX] and quantity.volume.

No such properties exist for Object type element in Archicad.

Hello,

There's no generic way to obtain that information because the GDL language used to create those objects allows free-form geometry. I can think of two ways to approach this:

1. Check the object's parameters (in memo.params) and look at the GDL script of that object to see which parameter may contain the information you need.

2. Get the 3D representation of the object. If you can figure out which planes of the object are the end planes (e.g., from the plane's normal vector), then you can calculate the slant angle and distance.

Best, Akos
