One can set the thickness of a surface model by either "part based" or "surface based". Since Algor to 2015, change from "part based" to "surface based" defaults all values to zero. Each value has to be enterered separately. This can be very tiresome
A simple and very helpful modification to the UI would be for the "part based" values to be copied to every surface when the model was changed from "part based" to "surface base". (Offered a choice?). This would allow the option for inputting the most common value and then editing the others rather than inputting every thickness and normal point. For example, one model I am working on has 31 surfaces. 3 surfaces are one thickness, 3 surfaces are another thickness, 25 surfaces are another thickness. Editing 6 values would be quicker than entering 31 values.
