Hi,
First of all, I have to precise that I am completely new to Simplify3D, that I bought one hour ago. I have used Cura for one day, and wanted a software that gives me more control. So maybe I am missing something obvious.
I have loaded a model, and changed the settings for the supports, as I wanted square pillars instead of walls. This appears exactly as I want it on the model view, but when I click on "Prepare to print", the preview shows completely different supports, I have now walls. I have attached images of the 2 views.
I did not try to print it yet, but I guess I will get what is in the preview. Any idea why it is like this?
