Tech Tuesday is a weekly blog that addresses some of the most common questions and concerns that I hear throughout the previous week from users of BobCAD’s CNC software. Both customers and future customers are more than welcome to leave a comment on what they would like to see covered for the following Tech Tuesday. If you missed the last Tech Tuesday, click here.
Today’s Tech Tuesday is going show you the many ways you can create surface models BobCAD-CAM’s CNC software.
What is Surface Modeling
Surface models are used to create sections of your overall 3D design. In fairness surface models are not really models at all. They are surfaces, which add detail to your design.
Where do you find the Surface modeling tools BobCAD offers? On the Create 3D tab at the top of the screen.
You’ll see the surface modeling tools grouped together with the rest of the 3D modeling tools BobCAD has to offer.
When do you use surfaces? When your design has features that can not be created with prismatic shapes, like cubes, cylinders.
When creating surfaces you’ll use wireframe sketches to drive the surface creating method. What kind of wire frame you’ll need and how it’s configured is based on the surface your trying to create.
Each surface feature has a tooltip to help you understand how to use it.
You’ll also notice for those surface modeling tools that have multiple methods, use the drop down menu, This allows users to easily choose the feature they would like to use.
After you have selected the desired surfacing modeling feature, the data entry window will be populated with the geometry selection manager specific to that feature.
Use the selection manager to select and define the geometry used to create the surface. This is important because the selection manager allows you to make changes to your selection without having to start over. Controlling things like the chain direction, order of selection and adding to or taking away from your selected geometry.
