I'm completely new to 3D. I want to make a custom wall mount for a tablet device (Kindle Fire). I have access to existing 3D files for the Kindle fire. I figured it would be easier to start with that as the dimensions, curves, etc are perfect. So what I want to do is start with external frame of the existing model as internal edge of my my frame (i'd need to overlap the front quite a bit (here's a very rough sketch of what I want to do: http://www.avsforum.com/t/1376864/using-the-kindle-fire-as-a -home-automation-touchscreen#post_21294130
So two questions:
1. Is this a viable option, or just crazy talk?
2. What application would be best (for a noob with no idea bout 3D modelling). Would prefer free, but wouldn't mind investing $50-100 if I could try for free
Here are the basic steps:
Import the model.
Scale up by ~1% to give you some 'wiggle room'.
Use "Intersect with model" to subtract the Kindle shape from your final wall mount shape. Sketchup Make comes with 8 hours of Sketchup Pro and the capability to do boolean subtraction - so if you can do it in less than 8 hours it'll be a little easier.Trouble using SketchUp? Get my book "3D Printing with SketchUp" - http://bit.ly/1jQ4RtV
You can also do this with blender and as always there are multiple ways how to do it.
1. import to blender.
2. delete faces where you want to have opening an leaving only "internal edge of your frame"
3. play with solidify modifier until you get thickness on the outside
