How to Repair Imported Geometry. Working with CAD models created in other systems is always a challenge. Any time you transfer a model from CAD system “A” to CAD system “B” there can be issues. Think of it like trying to translate a complex poem from one language to another. Sometimes there will be a loss of meaning in translation. Similarly, when we read in a model from another CAD system into SOLIDWORKS, there can be issues as well.
This post will show you how to: Identify if you have an issueFind out where on the model the issue isFix the issue Here is our test case. However, when we try any modeling operations at all, even a simple sketch and extrude, it fails. What could be the cause of this? Let’s look at them in detail. First, when you originally import the STEP file you should see a menu that asks you if you would like to run Import Diagnostics. This will show you where the bad surfaces are. Many times this will work, and your model will be healed and you will be able to continue working with it in SOLIDWORKS. Large assemblies made easy. Finally, assemblies done right. Creating 3D Files for Printing - 3D Printer. The CAD to STL Process After designing a model in SolidWorks you can save the design as an STL file.
An STL file renders surfaces in the CAD design as a mesh of triangles. The number and size of the triangles determine how accurately curved surfaces are printed. You control the number and size of the triangles by setting the following parameters when you create the STL file from the CAD design: Chordal Tolerance / Deviation The maximum distance between the surface of the original design and the tessellated surface of the STL triangle. Angle Control The angular deviation allowed between adjacent triangles. STL File Format You usually have the option to save STL files in either binary or ASCII format. STL Geometry Check Model designs containing holes and gaps adversely affect the quality of the printed model. Design for 3D Printing with SolidWorks 2014. Never before has it been so easy to turn an idea into a physical object.
The intersection of powerful 3D modeling tools and new technologies like 3D printing has created new opportunities and have changed the way people think about design and manufacturing. With Windows 8.1, 3D printing is built-in, which makes it even easier and more seamless to print to your 3D printer. In this post I’ll talk about using SolidWorks 2014 CAD software to design a part for 3D printing based on a project I just completed.
SolidWorks is a Windows-exclusive application that is considered the “industry standard” 3D modeling tool for many design, simulation, and analysis engineering applications. The 2014 version of SolidWorks was just released this month, and is packed with great features and capabilities. Finished 3D printed phone case (left) and 3D assembly in SolidWorks (right) – click/tap to enlarge Designing a Phone Case with SolidWorks So you just bought a 3D printer. Iterative Design and Manufacturing. Best Practices for 3D Printing Parts. Sending your digital file to either a Stratasys Fused Deposition Modeling (FDM) or an Objet (Polyjet) 3D printer is much easier than you first might have thought. Did you know that your orientation and fill style will vary with the model’s intended use?
Here is a break down of 3D printing best practices that everyone should know. STL Orientation The models shown below each have their optimal build orientation, what features would have been important to you: Smooth surface finish? The orange impellor to the left is a favorite to build at a trade show, built standing erect as shown in a Dimension or Fortus FDM printer. The enclosures are two part models with each component built side by side delivering a fast model with acceptable surface finish. The motorcycle shock is a multiple part component that was post assembled, each built with their intended use taken into effect. Model Interior Support Fill The last step is selecting the support fill: Surround, Basic, Smart or Sparse.
A 3D Print Ready Jack O' Lantern in Solidworks. To start with, lets make the body of a pumkin. I don't want to just make a sphere with grooves in it, but something a little more irregular, and pumpkin-like. We still want to get this in the general ball park of a 3D printable size, so I'll put a guide shape in for reference.
There are a few ways you could create a slightly irregular round shape. You could do a revolve and then distort it. You could create several offset planes, draw regular curves on them and then sweep from one to the next, or you could create a profile of the shape and then sweep it nearly in a circle along a path. Since I want this shape to be nearly regular like a nice little pie pumpkin, and the grooves should flow from top to bottom, I'm going to create a profile of it from above, and make several planes with guide curves. For 3D printing The only concern for this step is to keep the sides from slanting out too steeply, so when creating the spines try to keep them more vertical than 45º.

You can gnaw on them all day like a charred piece of sandy camel leather. (Your computer can too.) But what are you to do when you want to send a profile merrily down a path in two directions? At once? In SolidWorks?! Well, can’t be done. BUT, you can use a single set of sketches and a couple features to get that sweep going the direction you want. SolidWorks Mid-plane Sweep It’s indescribable how many ways you can sweep a profile. Mid-plane-boundary-sweep.zip (SolidWorks 2011) Note: For those that already know how to use the Selection Manager, you can skip down to step 6. Create your Profile sketch and Path sketch.
Now, we could have modifies the boundary of the sweep in that step, but to get the sweep to continue in the opposite direction, it requires another step. Start a new Sweep feature. Extra SolidWorks Sweep Tip! You can add extra points or spline points to your path sketch to constrain (or snap) the Selection nodes to. 5 SolidWorks Tips You May Have Never Seen Before. Chances are if you’ve been around SolidWorks for any significant amount of time, you may have seen some of these before, but I’ll be surprised if more than a handful of seasoned SolidWorks users have seen all 5 of these tips and tricks. While I’ve shown countless tips and tricks for SolidWorks in my time, these 5 are some of my personal favorites. #5 Selecting an Edge and Starting a Sketch This particular feature simply does several things with minimal input… a SolidWorks trademark.
Simply select any Edge of any solid body and click INSERT | SKETCH.A Sketch Plane is created automatically, Normal to the Edge Selected, with the Origin Coincident to the End Point nearest to where the Edge was selected. This operation supports any Edge type from Linear and Prismatic to completely Organic and Lofted.You could also use INSERT | Reference Geometry to add a Plane Perpendicular to a Curve, but this takes care of all those steps AND starts a new Sketch. #4 Loop Select **Loop Select BONUS**
