Below is our cheat sheet of what some of those letter mean, and what that file is good for.sldprt /.

However, in our imperfect world you will often have files show up in your email with weird letters at the end of them, regardless of the instructions you give.

This will typically be a solid model drawn in a professional CAD package like Solidworks, Pro-E, IronCAD, or similar. You also need to ensure the designer created it with enough information to begin with. So to ensure you really own your design, you need access to the original file it was created in. The key concept is that although systems files can often be exported to another, each time this happens information will be lost, and it can’t be brought back without a lot of hands on work. Whew! Still with us? Now that we have busted some jargon, let’s see what that means for someone who just wants a useable file of something they have had designed for them. They take information defined in one way are recalculate it to be used by a system that needs the information in another format.

Export files are visual representations of 3D designs.

Container file types are a means of consolidating multiple files or components of a design into one file for ease of reference and editing of the whole design.

Started your design 300 steps ago with a with a box that was too small? That’s ok, just edit that step and watch everything that was based on it update! Underlying steps can also be edited separately. The power of this type of construction is very complex shapes can be created step by step. Draw a box, then cut a hole out of the side, then add a block to one end, and so on.

Historical or Feature based file types build shapes from a series of instructions.Instead of using complex formulas to define every single bitty bit of the shape, they define a series of points floating in space, and then link those points up into flat shapes (polygons) which become the surface. Mesh, or polygonal, models, are the yin to a the solid models yang.They allow the designer to ask almost any question about a model and get an accurate answer about how it would react in the real world. They use complex formulas to define what the shape is, what’s inside it, and what’s not. They model the whole shape, all the way though. Solid Models are what they sound like.As with the difference between mechanical CAD and other sytles, the terms below come down to one concept, “how does the program store the data that makes up the model?”

Herein lies the jargon! don’t be scared though. You can also print out a flat drawing, which is a benefit that should not be underestimated. The flat drawing may get the info across just fine.

Some designs do not require a full 3D model. The answer is complexity usually comes at the cost of time, and you pay for designers time.

You may wonder why in this day and age designers bother with plain old flat drawings that have more in common with the ACME blueprints from a Road Runner cartoon than a pretty computer render. Mechanical CAD formats can be broken into those that focus on 2 dimensional (flat) drawings, and those that focus on 3 dimensional shapes. The Basic Divide – 2D and 3D Mechanical CAD

This means that the similarities are only skin deep. It may seem like they are all doing the same thing (making a model on a screen), but the type of problem each programs is trying to solve is quite different. Electrical engineers have specialised CAD to simulate the functioning circuitry as well as its physical size, and so on. For example, architects use a whole suite of specialty systems designed to handle the scale of their projects, but not focused on the fractional accuracy of mechanical CAD. They can also simulate movement, forces, weights and other physical properties. To give the designer as much power as possible, these programs can precisely model dimensions ranging from a micron (.001mm) to multiple kilometres. These systems are designed to make accurate representations of object that exist (or want to exist) in the real world. The World.ĭesigners and mechanical engineers in the field of product development deal mainly with mechanical CAD systems. We are aiming for a quick overview to allow you to get the files you need from one party to another with a minimum of fuss and cost. Last week, we explored the one question you need to ask to ensure you get a CAD format you can use: “will I own the design?”īut which formats are the ones you’ll own? How can you be sure that the next in your production chain can use what your designer hands you?īe aware this topic is incredibly complex.
