Explode Command on railings
This issue looks like it is related to the use of the metric shapes in an imperial project. It looks as though the scaled down shape is being drawn at the bottom right of the extents of the non-scaled shape, hence the incorrect position.
When the railing is then exploded the kick plate is (as you stated) being scaled back up. I will log this with our developers.
Default kick plate
The issue with the default kick plate shape not being available has been logged with our developers and has been scheduled to be fixed in the next release of the product.
Note:
I tested in the beta version and the FB* kick plates can be selected from the AISC standard. As this is now considered a developers issue I will go ahead and close this support case.
With regard to the kick plate height, the setting is to the top of the kick plate so if you set it to 1 inch the I suspect it is likely to be lower than required.
Try setting the height to a value greater than the height of the plate.
Issues with structural railing in Plant 3D
I have looked at this again and there does appear to be an issue with modifying imperial based project Railings with the DIN and CISC.
I will submit a change request with our development team for this issue. In the meantime you should use the AISC shape standard.
Hope this helps!
Stassel.
