How to Purchase 3D software

How to Purchase 3D software? That is a important problem to 3d designer. Now , Let's share some experiences about purchasing 3D software.

If you want to Purchase 3D software,Plese ask yourself the following questions:

1. What type of parts do you make (injection molded, machined, cast, etc.)?
2. Does your company plan to use the 3D model design for downstream processes? If so, which processes?
3. What level of accuracy does your company require? Determine the level of accuracy (third order or above) in the wire frame, surface, and solid geometry needed to produce your designs. Find out if the software under consideration supports this level of accuracy.
4. Does the software under consideration support all required engineering design and analysis functions?
5. How will you maintain your existing designs (legacy data)?
6. Will your existing staff be sufficient to support the new software and hardware?
7. How long before your current personnel become productive with 3D modeling software?
8. Will the software purchase require your company to purchase new hardware?
9. What hardware is needed? Be careful! The cost per 3D modeling workstation can be very misleading. Most software is packaged in some modular fashion. When you compare 3D design software costs, be sure to compare apples to apples.

So, I beleive you can do you best for Purchaseing 3D CAD.
