If I had the talent, knowledge, and the tools to make 3D computer models, I definitely would consider doing it. I'm not talking about being able to make simple shapes, but to be able to make models of subjects, complete with details and textures.
I would agree that it takes a lot of the same thought when it comes to details. One difference is that with 3D models you don't always have instructions and ready-to assemble pieces.
What are some of the important aspects of modeling?
1) Creating a finished model by assembling a various assortment of parts together, improvising when necessary.
2) Having fun -- enjoying the building of the model.
3) Being able to show off the finished model to others.
Sounds like computer modeling would fit right in.
Some people use plastic, resin, wood, paper or whatever else they can get their hands on. Computer modelers use virtual materials - 1's and 0's. Both enjoy what they do. Spouses may still complain about the time and money spent on either. Those not involved with either may still deem them as toys. A lot of similiarities.
Oh -- cats can hit the delete key and do just as much damage.
