Swept Path Envelope and Tapers

Clicking the Show Swept Path Envelope button will display polygons that show the shape of the Swept Path. This is what would be seen in Spider Path. Clicking on the Cab will also show the Envelopes.
Clicking on the Envelope will show the Taper dimensions. These can also be edited on the Property Panel under the Vehicle Unit.
Tapers can be added so the shape fits the Vehicle Unit (for example cab curbe, fridge vans). If using Front or Rear Bumpers or Bullbars, then the tapers will be locked to follow those equipment's properties.
These tapers will be shown in Spider Path as well.
