The Class 43 Locomotive

The Class 43 locomotive is depicted at the top of this post. I’m designing the prototype model of the Class 43 in HO (1:87) scale, starting from the blueprint: I scan the drawing, I use it as a trace to follow ext_profile_fr.pngto draw the profile with Inkscape, then I import the 2D profiles into FreeCAD to be extruded and create the 3D model of the ext_profile_ax_view.pnglocomotive parts. Finally I combine the 3D blocks together to build the complete model to be sent to the 3D printer.
