Material Volume not calculated

Hi there,

First – thank you for this amazing Plugin. But i′m having Trouble with the calculation of estimated Price as it stays the same, no matter what material i choose. The Material Volume, Model Weight and Surface Area is always Zero. Allready tried different Calculation Methods but none worked. Could you please help me? As soon as my Business is going to run i will purchase the Proversion, but untill then ill need to use the Freeversion. THX in forward, Greetz Patrick
