The Rails op generates surfaces by stretching cross-sections between two rails. This is similar to the Sweep SOP, but it gives more control over the orientation and scaling of the cross-sections. The first op input is the cross-section which will be replicated, and is typically placed in the XY plane. The second input op source is the rails along which the cross-section is replicated.
Click the Rails tool on the Model tab.
Select the cross-section and press Enter to confirm your selection.
You can attach multiple cross-sections to rails by selecting more than one.
Select the rails and press Enter to confirm your selection.
You can scale the cross-sections in the parameter editor or the operation controls toolbar.
