curve.ifc (1.7 KB)
I’m trying to figure out why the above file won’t be displayed (correctly or at all) in any of the viewers I tried (Blender with BlenderBIM, ifc-view.com, ifcviewer). It’s supposed to be a curved pipe, the curve’s angle being 0.79 rad, roughly equivalent to 45°. The only program able to display the solid is ifcviewer, and this is how it looks:
Obviously that’s not how I want it to be, because the curve has an angle bigger than 0.79 rad.
According to the IFC specification, IfcSweptDiskSolid.StartParam and EndParam are the parameter values on the directrix at which the sweeping operation commences/ends. The directrix I’m using is an IfcCircle, and according to its specification the parameterization range is from 0 to 2*PI or from 0° to 360°. Since I’ve set radians as one of the project’s units, viewers should be able to pick up that the parameter values I gave were in radians, right?
