[ ]Board in Blender
My measurements 84.8x55.9x1 mm curved corners 2.5mm
Official schematics 85x56 curved corners 3mm
So I had done most of the work getting the bottom of board ready, just had not finalised it. Once that was done I used my digital calipers to measure the board. Then I checked online and found the schematics
My measurements were only 10ths of a millimetre off!
So I had a plan. Create a cube in Blender
and scale it to the circuit board size.
OK I knew there were rounded corners so I will just apply a subsurf modifier.
hmmm that seems to have distorted it somewhat.
Time for something new. This time I started with a plane and subdivided the sides to add vertexes to define the corners (using the official measurements) and set the segments to be NURBS to get the curves. The curves looked good but close up they extended and warped much more than just the corners. The fix was just to create more vertexes to define the other end of the curve(away from the corner) and set their location to be the same.
And that was it .. a part from the 2 hours of texture wrangling. This included trying to chase down a bizarre single pixel seam that for no good reason existed on the top edge away from all the other texture face islands. Also I had to learn about GIMP
s transparency Threshold Alpha...
tool to avoid the edges of the textures being see-through in the model.
Next will be to create the holes in the board. Got a couple of ideas ...
