Just a brief info about myself, I am using Alias AutoStudio professionally for almost 5 - 6 years at my work to model yachts and in rare occasions cars. I used Rhino as well, so I have some knowledge about nurbs modelling. I have always wanted to try polygonal modelling for it's sculpturing workflow but after brief tries with tutorials, I have always given up.
This time, I didn't. Last week I started modelling again in Blender, following millions of tutorials and designed a very detailed, beautiful watch with it's strap, exactly how I wanted and not how It was shown (design wise) on tutorials by mixing techniques that I have seen on many tutorials and forums. Once it was done, I moved to model a shoe of a friend's shoe brand and so far so good. I actually never liked the modelling part of my job but I should admit that I am having so much fun modelling with blender because I find it more attached to design experimenting in a faster way and that was the reason I wanted to learn it. To make some fast "mock-up" models before moving to Alias or Rhino to make a very precise version. Ok, here's my question:
I am having trouble with the units system of Blender. I mean, since the objects that I am modelling are relatively small in size, I changed the unit to cm instead of meter from the Scene Options and the unit scale is 1.000000. Then I set some planes with the sizes that I wanted as a reference as if it was a ruler to model a relatively "precise" modelling, at least proportion wise. Everything was ok on my watch modelling because there I had not changed the units, but on the shoe one, I encountered two problems:
Whatever I add to my scene with shift + A is huge, so everytime, anything, I have/had to scale down to make it useable on my shoe model. Is there a way to fix it?
When I was modelling the watch, I found a tool that I loved using, proportional editing. I have a problem with scale again on the shoe. When I select a vertex and activate proportional editing, when I am using 0.01 it is not effecting any other vertex, when I am using 0.15 it is effecting even the vertexes on the other side of the shoe, so I have very little control on the step size of the proportional transform. When I was modelling the watch, I had not changed the units and kept everything as it is and instead of modelling a 42 mm watch, I had modelled 42 m watch, just to learn the basics first and when I was using with it the proportional transformer, I could play between 2 to 25 proportional size value which gave me a greater control to fine-tune things.
I am encountering a problem in the Merge by Distance as well. when I raise the value just a little bit, it is starting to merge vertexes close by whereas again with the watch model, I had a much broader range of values to play with and choose more precisely.
Searched google, forums, youtube..etc about it and could not find anything, so I finally decided to post here. If you could help, I would appreciate it as I am really enjoying using Blender and it is unbeleivable how powerful this tool is at a free cost compared to some much more expensive options. Thank you Blender team for giving us this opportunity.
