I like to make home projects, for example building a bed or a loft or a soundproof room. I also want to design my own house to build. Currently I do the old paper and pen method, but this is limited. I'm finally considering learning some basic 3D modeling.
What is a good easy 3D modeling software with a low learning curve to use for this type of thing? I am an expert in photoshop so I am very competent with computers, I just don't have the time to spend many hours learning 3D modeling software - it's actually faster to use paper and pen the old way than spend all that time learning the software. So, I'm hoping to use a 3D software that will give me greater benefit and flexibility on home projects and home design while not spending too much time learning the software itself.
In addition in the longer term I want to learn building personal projects like designing inventions for a 3D printer etc.
Free or paid software are open. Whichever is best for my utility. Which software should I start with?
