Doubledaz posted two SCARM files in reply to my query. These files are complex with multiple levels, tracks, benchwork, etc. Looking at these really jump started my efforts. I recommend them to others looking to jump in.
I started by setting up many levels following DAZ. These really help. Then I set about defining the room. I got it done, but I found it hard to be precise. Using the ruler I see that I am plus or minus a couple of inches over the 30 foot room. When creating an object, I don't see anywhere to see the size of the object, other than the rulers at the top and side, that are difficult to use with precision. I have been using the measuring tape. Am I missing something? Is there a way to see the dimensions of an object? Can live with the precision that I have.
I added text. Is there a way to adjust the font size?
I started preliminary track and dealing with the height seems quirky. I sometimes get odd results and don't know why, but gradually gaining on it.
