Freeform Surface Modeling

Fill out our quote form, attach your files, or simply send us an email. Tell everything about your project, like the model purpose.

For smaller files < 15 MB you can simply email them to us.  For something larger, just drop them in any number of drop boxes like Dropbox, Google Drive, Microsoft OneDrive and others.  Or if you would like, just contact us for a private, hardened link.

It is fine to use most any time of compression such as  *.zip, *.rar, *.tar, *.7z, *.arc, *.LBR, and even *.iso images.

A direct email is [email protected]

We also use a hardened OwnCloud web file sharing platform for unlimited file transfers. We provide unique and very private Web Storage Portals, this also supports file syncing for extreme convenience for you. Because so much of our work is DOD or weapons design work, Security – and confidentiality is very important to us.

Yes. NDAs are a common part of our business. All data is yours – not ours, and treated as proprietary data and not for public consumption or use. Probably 70% of our work is under NDA agreements. We can generally get these signed within the day.

It depends on the scope of work:

• 2D drawings – small quantity, normally 48 hours.  We have several customers where they contract to us, keeping 4-8 drafters busy full time.
• 3D models – complexity dependent, but smaller jobs in 2-3 days. Some models we have spent months on.  Again, we have several customers where they contract to us, keeping 6-10 3D CAD designers busy full time.

Simple jobs have a lead time of 48 hours. Larger projects are delivered and invoiced weekly.

Yes, we did back in 2008. We started using Cad Perfect™ back in the early 1990s because all of our customers wanted only real Cad Perfect™ work. Back then the buzz words were terms like machine ready, or DXF Traceover and others.

The problem is, nobody wanted that. They all wanted drawings and models that they did not have to touch. Everybody wanted drawings just as if they hand redrew the work themselves.

Thus, Cad / Cam Services™ was the first company to start offering ONLY Cad Perfect™ work.

Yes we do, and have now for several years. In addition, we also support the industry specific plans as well.

Per hour. Hourly rate depends on what CAD software used and typically starts at $75 per hour.  In general, to make this process safer for you, we often provide you a fixed not to exceed the cost as well.  That way, you are protected from an open-ended PO. However, the reality is our fees are based on time. In addition, services in say Catia or NX are more expensive than say Solidworks. Or, simulation services are commonly done by real engineers.

First of all, we need to know the target CAD system and whether you have an existing  template, or set of CAD standards for this project.

The main question is the overall complexity. As each part and assembly consists of different features and elements the best way is to provide us with an example.  Again, a picture is worth a thousand words.

If you already have a model and need us to improve it or update it in any way we need to know which dimensions and features are critical and which can be modified to achieve your desired result.  Even a before and after example works very well. We started with x, and got to this CAD file.

We can also offer you better options if you provide us with the purpose of your project (demonstration, 3D printing, FEA Simulation, CNC manufacturing, etc.).  This helps us better refine the task.

We create 2D drawings from our 3D models for QC purposes. We follow aerospace standards and deliver ±.005” accuracy models for all projects.  All of our QC is done by a different person than the designer. On Catia work, we often use Q-Checker for Airbus.

We have a minimum order fee $150.

A Finite Element Analysis (FEA) is a form of non-destructive testing (NDT) that shows how your part reacts to real-world loading events. A common example is running an FEA on a support bracket. The FEA will give results showing how much the bracket deflects, how much reactive force is seen, and the kind of internal stresses the bracket experiences.

‍

FEA results will change dramatically based on the position and angle of the load, how much force is applied, the material properties of the part, and the design of the part itself.

‍

An FEA is used to optimize a part before manufacturing begins. It allows you to find weak points within your part or assembly, and it will predict a failure before you physically make anything. This gives you an opportunity to fine-tune each part to optimize its size, strength, and cost before you start producing it.

The more information we have, the more accurate the simulation results will be. It also depends on what type of simulation you want to run. For a simple FEA, we can run an accurate simulation with just a 3D CAD model and loading/force/pressure information that you want to simulate.

‍

Don’t have a 3D model? Not a problem, our team can make one for you from scratch, and then run an FEA on it.

‍

For a more detailed answer, a well-run FEA will need:

‍

• Material properties: What material is the part made out of? We can run different FEAs with different materials to help you pick the right one.

• Loading conditions: The size, location, and type of load you want to simulate.

• Bonding condition: How is the part held in place? Is it bolted, welded, or just sitting on a tabletop?

• A 3D model

• For other simulations: Please provide us with all thermal, dynamic, aero, and/or fluid flow information. Feel free to call us and we’ll walk you through what we need.
