Perhaps I was too quick to judge Google Sketchup in my last post. I still dislike many things about it but it is a capable package.
The h12 is slightly different from what is normally built. I have moved the blocks that connect the roof and the wall to the inside. They are normally on the outside to ease fitting however, I moved them inside because of my solo build modification.
The h13 is still very rough for now. Many of the joining blocks have yet to be added and construction lines lurking in corners. The door is still half height. The multiple overlaps have created a mess. I have left many of the panels clipping through each other. If someone with more experience of this build could take a look and tell me what are the best parts to trim that would be great. Also I was unsure of what would be the best way to organise the overlapping for the roof.
Once both models are perfected I will try and host them in an open-source format. Tri-platform if possible (Win/Mac/Linux).
My next plans are to create blue prints with full dimensions for both models and IKEA style construction instructions. Once that is done, then I can finally begin the proper solo build instruction manual that started all this.
PS. Are there any other variants that people would like a model of?
