I can design and edit FreeCAD 3D file for you for outputs as 3D-prints, prototypes projects and developments towards commercial products.
I have decades of experience using older version AutoCAD's in many different ways which I have have transferred the skill into using FreeCAD on Linux based systems for outputting designs to a 3D-printer and I now have quite an amount of experience dealing with all the various issues that come about in FreeCAD file problems in 3D.
I can take your 2D designs and convert them into 3D designs ready for printing on a 3D printer and I can debug a large number of the problems that you can get in doing this.
my skills and abilities are available for a price.
At the simplest level I can take FreeCAD file designs that you cannot get to work on 3D FreeCAD and quite often and quite often development into actions that will work. However this can be quite simple sometimes and it can also get quite complicated and time-consuming.
I have the skill and knowledge to do such things at a price.
