Rick, I have followed your advise and made blocks of my valve subassemblies and housing. I am a little confused though as to the process one would take in starting from scratch with a new design using 2D. My take is to make details using the 2D model from which one would prepare 2D drawings. A final assembly would be prepared from blocks of the details to call out parts and envelope dimensions. I talked with Joseph Riden of the SE Users Group who encouraged 3D and noted that blocks were a carry over from AutoCad and he did not use blocks. I understand that with 3D one would first generate a 3D model and 2D details would be easily forthcoming. Any advise here would be appreciated. Gil Tellier
Gil, I know there is a question here somewhere but I don't quite know what it is. You can simulate assemblies with blocks as you did with the example I sent to you earlier. In that example all the blocks were in the same draft file. As long as the 2D geometry is simple, you can create a separate 2D Model(draft file) for each part. If you get into drawing multiple 2D views (top, front, etc.) this technique will become more difficult. You would need to create a separate block for each view orientation of each part(draft file). Once you have your separate 2D parts drawn, you can create a new draft file and use it as the assembled drawing. Place the blocks in this file referencing the blocks from the other 2D part(draft) files. When you do this, there is no automatic update of the blocks you assemble. If changes are made to the original blocks, you will have to delete and place the block again in the assembly drawing. You are getting to the point now where you are stretching the limitations of the block capabilities. This is where going 3D would be the prefered method. You would build your parts in 3D. The parts will be assembled in 3D. You create your drawings from the 3D models. The assembly and drawings will associatively update with changes to the 3D models. Hope this helps, Rick B.
