I am very happy to hear that you finally got it to work.
I thought we had covered that one in post # 11?
In addition to having your SOLIDHIST to 1, you will notice that I have selected in the palette to RECORD, the default is NONE.
Once you do that it will all start to work for you.
As just about anything you draw in the program could be the first step of a new solid history
I believe you will need to RECORD, when you want it to.
I know it is difficult having so many different approaches and suggestions being offered
all at the same time, but if a suggestion is made, the forum members have to assume that it has been tried,
and failed, unless we hear otherwise, which leaves us no other choice than to try a different solution.
