+The screenshot above is a solar oven I designed using librecad.  The oven is for a community garden in Gaillac, France where I live.
 
+Ferdie, my global evaluator, asked me to add a few words about my 2d design process.   I used the mouse not the command line in librecad.  For almost all cases, I am an anti-command line kind of guy - machines and software should be designed to adapt to the cognitive capabilities of humans, which are considerable, and not force humans to adapt to machines (see Norman, Don  The Design of Everyday Things and Rose, David  Enchanted Objects: Innovation, Design, and teh Future of Technology).  I find the emphasis and merit given in Fabacademy to complex ways to do simple things offensive and against the spirit of the democratization of technology.   
 
 
+I use gimp for raster based design work and librecad and inkscape for vector based design work although each program is able to do a bit of what the other can do.  
+
+Here's what I do if I find a raster graphic (jpeg etc) that I want to add to a librecad (vector) design for cutting on a laser cutter.
+
+1. I find a graphic I like on line or design one with inkscape.  
+2. If it is a raster based image I import it into Inkscape and convert it to a vector file.   
+3. I export it as an SVG or DXF file, both vector based images. 
+4. I import the vector file made by inkscape into librecad.  
+5.  I then move and resize the image as needed in librecad

+I found the sun image  on the internet and used the process above to convert it to a vector file for import into librecad.

+![Front of oven](../images/week02-images/partage_solar_oven_front.jpeg)
+
+I used the text capabilities of librecad to create the text.  
+
+Could have used multiple passes, more power, or slower speed to make the graphics and letters darker.   
+
+This is the kind of thing I hoped to do more during fabacademy - build things like solar ovens and musical instruments.  Sadly most of fabacademy, probably 70% for me, was spent wrestling with unreliable hardware and software to design and build microprocessor boards that are readily and inexpensively available commercially.
