I also built the file for the track. It was a quicky.
The vectors were simple. Two parallel rails would form the bent track. The other vector required was the profile of half of a cross section of a train rail. I used the sweep two rails command, and followed the prompts
When it performs the task it shows black until I hit the render button. Meshes show up red. Meshes cannot be tool pathed. We first have to convert them to reliefs.
In order to do this I first created a zero height relief. using my outline vector.
The rail mesh needs to be positioned correctly in the vertical space as I would be adding this volume to the flat, zero height relief. I did this in the front view with the up/down keys.
Then I selected both the relief and mesh to light up the mesh/relief merge button. In this case I could have used either the add to relief of merge highest.
When I render after merging the mesh and relief it comes out as splotchy red/yellow. I can then move/delete the mesh.
I used a five minute epoxy to glue the two halves together.
I used my trusty air-powered die grinder to whip up some railroad ties. This thing is coming together in a hurry... the hard part is done.
Stay tuned as more parts come together...
