Is it possible to add hotspots that change the angle of inclination, such as beam elements, to a GDL-created shape such as a cylind on a sectional view??
I know this is difficult because there is no reference line, but could this be accomplished by using some sort of 3D shape command?
Using the standard HOTSPOT command with the flags 4 to 7. If you want your hotspots to move with the vertices, you would just need to incorporate some trigonometry, sin and cosine, into the x & y inputs to bound it to a circle.
Or, given your example, in which the object is just bound to the one axis, you can skip this, since you are not bound to a circle, and just define a hotspot for the z-axis. Use cos(pitch) to calculate your top / bottom hotspot difference. If you wish to have move flexibility than that it could get complicated very fast...
To do that I would use the CUTPLANE commands and extend the profile and arbitary amount in both directions to ensure it is vertical.
!Top CUTPLANE 1, 0, 1, 1 !Bottom CUTPLANE 1, 0, 1, 0
It is possible. In my case I am creating my own selectable profiles for specialist objects. If you want to know how to use AC Complex Profiles for your beams then you won't find that in CB3. I don't like AC's Param-O add-on, but what I found useful was placing a complex profile beam in a Param-O object and then looking at the generated GDL code with the GDL manual.
