I have just read the excellent article, in MEW No. 262, by Darren Conway on 3D Printing and decided to download the free CAD programme that he used, Designspark Mechanical..
I downloaded this from the Web and it appears to have successfully installed on my computer. However, I have been unable to register to use the programme, as required before use, I keep receiving error messages and despite many attempts to complete and submit the registration form have still not been able to "unlock" the software. I have also been unable to find an email address for Designspark to enable me to contact them for assistance.
Have anyone else had this problem? (I see that there were similar issues with Designspark back in 2014, which were referenced on this forum).
