Retrieve LCS of LinseSegment3D #5

Closed BouwenmetStaal closed 4 years ago

BouwenmetStaal commented 5 years ago

I want to make a plate that is orientated based on the local coordinate system (LCS) of the attached beam.

In order to do so, I want to retrieve the LCS-vectors of the beam and implement them in the LCS of the plate. However, in the Class CoordSystem, the properties cannot be retrieved:

CoordSystem coor = openModel.LineSegment3D[refBeam].LocalCoordinateSystem; https://idea-statica.github.io/iom/iom-api/latest/html/25041a51-98ad-91db-c8b9-a13c9d3637a9.htm

How can I retrieve the LCS of a LineSegment3D?

You need to create LCS for plates manually - it is the transformation matrix. You can not read it from LineSegment3D

Unfortunately,

It might be something to include in the next version?

It would be very useful.

We have published IdeaStatiCa.PluginsTools (it is BETA now, it will be released in November)

https://github.com/idea-statica/ideastatica-plugin/tree/idea-statica-v20i

You will find the class

CI.Geometry3D.Matrix44

which includes methods

CI.Geometry3D.Matrix44.TransformToGCS / CI.Geometry3D.Matrix44.TransformToLCS

it heps to transform LCS <-> GCS
