I do not wish to give details at this stage, but those of you who are familiar with this website, will know that I have a page devoted to the building of 3D interactive Meccano® models using my set of virtual Meccano® parts. Well, this app will give you a chance of piecing together a simple interactive realtime virtual model (although nothing can replace the enjoyment of assembling real physical Meccano® parts) It is NOT a CAD app, but enables a beginner to gain an understanding of working in a virtual 3D environment, without getting confused by a lot of terminology.
I estimate at least a further 2 months until completion, whereupon I will issue a free demo. From then on, depending on user feedback, I will be issuing derivative works for which I will charge a small fee.
