I just created a TWD in V6.
Much better interface BUT -
when ask if I wanted to change material thickness, I measured what I had and said yes.
I changed the thickness and it created my TWD just fine.
I later went to open this file again and found the program had changed the material thickness in the data base and wanted to make new material.
I don't want the program to permanently change my material. I just want it changed for this job. RIGHT?
I have a thread going on this and posted a new reply for Rick at Thermwood to take a look at this. I verified this is happening after I saw you mention it on the ShopBot forum. Good catch!
