Algorithm (Workflow)

This function, SGofSGTsurface, is designed to return the flange surface for a given T matrix frame name. It is part of the SolidGeometry library and was introduced in version 4.3.

Input Parameters

SGT: Solid Geometry object.
FNam: Name of the Frame.
t: Thickness of the solid; default value is 0.5.
d: Distance from the surface; default value is 0.3.
s: Stretching of the border line; default value is 0.

Output

SG: Solid Geometry object.

Algorithm Steps

Extract the Solid Geometry object SGT and the Frame Name FNam from the input arguments.
Retrieve the transformation matrix T for the given frame name using SGTget.
Set a default name NB for the new frame as 'B'.
Call the function VLFLofSGTsurface with the input arguments to obtain vertex list SG.VL and face list SG.FL.
Compute a new transformation matrix TB by multiplying T with a rotation matrix TofR(rot(0,pi,0)).
Set the new transformation matrix TB for the frame NB using SGTset.
If no output is requested, visualize the result:

Open a new figure with SGfigure and set the view angle.
Calculate the size of the bounding box s using sofBB.
Plot the original geometry with SGplot and set lighting.
Plot the transformation T and TB with tplot.
Plot the new solid geometry SG and adjust lighting.
