Interactive Mobius Strip Generator for Geomagic Design
This mini tutorial shows how to generate custom Mobius strips with minimum effort. It demonstrates that python scripting can be used to ask the user for information and then apply it to a part the user is already working on. Hopefully that will be useful to some people when solving problems.
1. Download and install WizoScript 1.70 or later and start it.
2. Start Geomagic Design V16 hotfix 1 (18.104.22.16890) or later.
3. Create a new part and set the units to millimeters.
4. Create a new sketch on the XY plane.
5. Draw a triangle centered on the X axis and set the size of the reference circle to 10mm.
6. Set the center of the triangle 30mm from the origin and exit sketch editing mode.
7. Go to the WizoScript script library and copy the Interactive Mobius Strip Generator. Paste it into WizoScript. Hint: double-clicking on the script in the web-page selects the entire script.
8. Run the script.
9. You will be asked for the name of the part. Assuming you haven’t saved it enter “New Part (1)”. Then you will be asked for the name of the sketch. Enter “Sketch<1>”.
10. Next you will be asked the rotation point along the X axis. Enter “30”. This puts the rotation point at the center of the triangle.
11. You will be asked for the number of rotations. This is the number of times the mobius strip will completely rotate. Enter “3”.
12. Finally you will be asked to enter the number of steps. Enter “30”.
Now the mobius strip will be generated. Be patient as this can take several minutes. Here is what you should have:
Now it’s time to experiment! You can change the shape of the sketch to create different effects. Setting the rotation point closer or further away from the origin will create a “corkscrew” effect. You can increase or decrease the number of rotations. Reducing the number of steps will make the part faster to create but you might have to manually add a guide curve to get a true mobius strip.
Using this script it is possible to run it multiple times on the same part. For example create two sketches, run it on the first sketch and then run it on the second sketch to create two Mobius strips that are intertwined.

Introduction This tutorial demonstrates how to create a library of parts in a CAD neutral format based on a single template part. It takes advantage of parameterization in Geomagic Design. We will start by creating the base part that we will use to create the library. This will be a simple cap head bolt. Next…

The Cooke Triplet is a system of three lenses designed in the 19th century to reduce distortion. In 1950 a specific triplet was invented and patented by Eastman Kodak (EF=100mm, f/1.9) and we will look at how to recreate it in Geomagic Design using scripting. We will create a script that can generate any type…

The most common type of gear is the involute gear, which provides smooth and efficient operation. A gear is defined by the following parameters: Pitch diameter (diameter of gear) Diametral pitch (tooth size) Number of teeth Pressure angle (commonly 14.5, 20 or 25 degrees) The pressure angle defines the shape of a tooth. For two…

Creating screws is tedious. There are lots of diameter and length combinations and there is more to a screw than first meets the eye. Creating a parts library containing lots of variations is a perfect use for ADScript. Here is a M3 x 20mm socket cap screw generated from the script below. This screw is…

ADScript makes it easy to use Alibre Design with Python scripting. For example creating a new part: We can get access to planes in the design workspace, for example: Once we have a part and plane we can create a sketch on the plane: Adding to the sketch is easy: Now we can extrude it:…

FreeCAD supports Python as a scripting language which allows the creation of 3D parts based on variables. This is great for building libraries which support customizable part creation. As a first attempt I created the following test script. When executed in FreeCAD 0.13 it creates a rod 10mm x 10mm x 50mm with a notch…
