I decided 3D modeling software!

I google estimations for 3D modeling software, so I decided to use '123D Design' by Autodesk.

How do I decided?
   - Free, but it has enough functions.
   - It's able to use cloud and local PC storage.
   - Many persons said good estimations.

Before installing.
I want to raise the power on my PC that it has memory 4GBite and Windows7 32bit.
   + Memory up to 8GBite.
   + Upgrade free Windows10 with 64bit.for now.
At first, Windows7 upgrade to Windows10 32bit then Windows10 32bit change to Windows10 64bit. But, Changing 64bit can only clean install, so I did backup private files before those working.
WIndows7 upgrade Windows10 64bit.
   1. Download Windows10 64bit iso file from MS and burn bootable medium DVD or USB.
   2. Backup private files.
   3. Upgrade Windows7 32bit to Windows10 32bit
   4. Boot from Windows10 64bit.
   5. Update Windows.(Do not new install)
   6. Restore private files.
OK, My PC.

Setup 123D Design.
   1. An installer file(Windows64bit) download from '123D Design'.
   2. Downloaded installer file run and start installing.
   3. Make 123D account.


Let's call it a day!
