Are you sick and tired of broken promise after broken promise when dealing with the aftermarket industry CAD Design? Are frustrations with your current design / development source causing you to loose sleep at night? Are you finding that lack of experience and basic business ethics causing you problems down the road when it comes to design and development?

Frequently Asked Questions about CAD Design

How much does "X" design cost?

Well it actually will not cost you anything…. because the service GMR performs is actually an Investment that will aid you in furthering your business and product line. Depending the project you need accomplished the investment will vary, this is R&D after all and predicting exact investment is hard to do when something has yet to be created. Please email GMR below for any inquiries or questions.

How long does it take to design "X" ?

Just like everything in the custom aftermarket world this is not exactly a perfect science and time is very difficult to estimate. However we have through my years of experience been able to make and keep realistic deadlines, the key is that they are realistic. We are very upfront with you about deadlines and time frames, GMR only takes on 2-3 projects at a time to ensure that everyone is happy and deadlines set are met. This also ensures that when we take on a project we are actually working on it, unlike the industry standard of taking deposits then letting projects sit for months…

What can I expect from GMR in regards to computer Files?

GMR strictly uses CATIA for all CAD work but the outcome with files is the same with every program. We can work closely with your Laser / Water Cutting company or Machinist to ensure that all files transfer over properly. We can provide files in Solidworks, STP, IGES, DXF, and CATIA formats. Typically for all laser cut plate parts we section all the material and items into Cut-lists that combine Excel spreadsheets with matching folders of the DXF files.

Can things be changed / revised through the process or after?

Yes, you can add changes and revisions at any time through the process. Just keep in mind that the changes and revisions can add large chunks of time which will add to the investment total of the project. We can makes adjustments while in the middle of the design phase and even years after, it all depends on what you want to do.

Can I purchase designs you already have?

Unfortunately most designs I can not sell, they belong to the companies / individuals that contract GMR to create them. Sometimes GMR has our own designs that we can sell, only if they have not been previously sold to anyone else. It would be unethical to sell designs that were created for another party.
