Got the homosote down and laid out the 1:1 printout from Scarm. Everything fits like it's sposda fit.
I recall having to add text to the print sheets manually to create a grid to enable assembly of the pieces. Did that happen automatically?
Then, I became more clever and left out the blank or mostly blank sections when I set the print parameters. Saved a 1/3 of ream of paper. I teased the SCARM author that this feature was for the HO, N and Z scale guys.
I like SCARM because of the grid layout features - everything can be designed to build out as it should with careful measurement and layout setup.
That should make it easy to place the track.
