Thanks for the welcome. I started modeling about 70 years ago and have been mostly building 1/72 scale aircraft. I have recently started using 3D printing to add to my toolbox and can see where it can be a very useful addition. Now I need to learn to use some of the 3D drawing software so I can use them even more. I am retired and have recently decided to start building a N scale railroad layout. So far about all I have done is collect some rolling stock and a lot of ideas. I am still looking for the right track plan to get started. I am thinking about somewhere in the1930s to 1950s time period. That way I can run steam and deasil both, and I am leaning towards a DCC system with at least 3 or 4 trains on a 4 x 8 layout. That is about as far as I have go so far. I have looked at a lot of track plans but haven't seen anything that looks like something I would like to try. At this time, I thing a lot of my structures will be card models. Less painting for me and I am comfortable with their construction, plus I have a growing file of then already. Again thanks for the welcome and I enjoy reading about what a lot of you have been doing and hope that some day I can be a little more than a outside lurker and an active builder. Right now my online sources are about all I have, as there do not appear to be many modelers of any type in the area where I live., as I am a little over an hour SE of from Dallas.
