I have been using Alibre for my drawings for some time, the learning curve is pretty steep and on an expertise scale of 1 to 10, I am still firmly at 1 or thereabouts! The latest version for 2013 has been renamed Geomagic Design following the purchase of Geomagic by Alibre’s parent company 3D Systems. There are a number of new features and some tweaks to the interface. There are different versions of the program with Geomagic Design Personal being the entry level that I have. Not all features are available in the Personal version but it is probably the most suitable for the home user and definitely the most affordable. There are plenty of free tutorial videos available and a useful users forum so the new user is well catered for. All you need is a brain slightly less fuzzy than mine…
After some time without new content I have finally added a new page. This is for a drill press hold down clamp. A useful adaptation of an old Mole Wrench which was lying unused in a box of bits that “might be useful one day”.
