Inspired somewhat by the 3DS Max utility, I present the Blender calculator for Shapeways costs (attachment). Requires Blender v2.48a or later v0.7 (8/28/2009): Added Dyed WSF and Polished Stainless materials WSF will add $1.50 to calculated price regardless of size, so don't worry about the price per cm3 not multiplying into the total Similarly, dyed WSF will add $4 to calculated price Changed WSF pricing to $1.50/cm3 An issue may arise when going from 0.6 to 0.7 with saved settings because of extra buttons... if something looks "wonky" when it loads, change to your preferred settings and exit, then run the script again. v0.6 (4/28/2009): Fixed a scaling/translation bug v0.5 (4/23/2009): Better script cleanup Changed GUI to single column, contracting sections Added Blender registry entries for persistent settings Added changeable material prices Added manifold check Added polygon count (current and triangulated) Added selection dimensions Fixed Blender unit scale errors: exponent was wrong, and reversed between millimetres and metres Slightly better support for scaling and translation calculation v0.4 (3/30/2009): Some script cleanup Using popup GUI form rather than script window. The new form should fit on screen more reliably v0.3 (3/27/2009): Fixed resizing calculation bug v0.2: Added GUI with changeable options, VAT and markup calculation, and resizing calculation Added quad support in addition to tris Scaling applied without manual application v0.1: Basic calculation sent to console window Preview: To install: extract the .py file to the base blender working directory (this may be your installation path, AppData, %HOME%, or something else on another O/S. Then start up Blender, it should be in the object->scripts menu. It will generally go to 1 of 2 places in Windows Example 1: C:\Program Files\Blender Foundation\Blender\.blender\scripts\ Example 2: Vista: C:\Users\username\AppData\Roaming\Blender Foundation\Blender\.blender\scripts\ XP: C:\Documents And Settings\username\Application Data\Blender Foundation\Blender\.blender\scripts\ To use: Select the objects you want to calculate, and run the script as shown here: This will display the GUI which should be self-explanatory. Let me know if anything could be explained easier. I'm working on a normal check and trying to figure out a wallthickness calculation, so I may update with that in a few weeks. I'll appreciate feedback; especially if something doesn't work.
