How to use 3D printing modeling software

Many people are very interested in 3D printers, but you need to use modeling software to model before 3D printer printing. Then how much do you know about 3D printing modeling software? In fact, there are many 3D printing modeling software, which can be classified according to the different products we print.


Next we will briefly talk about:

  1. Partial mechanical: Solidworks, ProE/Creo, UG, Catia, AutoCAD, Inventor
  2. Partial art: Rhino, 3Ds MAX, Maya, CINEMA 4D, Zbrush, Blender
  3. Beginner/education/experience: Shapr3D, 3Done, Google Sketchup, Paint 3D (included in Win10)
  4. 3D printing aids: Magics,123 D Design, Nefabb, we can easily find that there are many 3D printing modeling software, we can choose the one that suits us and learn slowly.


Next, we will take 3DS Max software as an example to talk about how to perform polygon modeling: There are two main commands for polygon modeling: Editable Mesh (editable mesh) and Editable Poly (editable polygon), generally we create one first The original geometry is collapsed into an editable mesh or editable polygon, and then continuously modified, and continuously subdivided to obtain the model effect we want.


Create two new boxes, and then collapse them into editable meshes and editable polygons in the modification stack. Open the modification stack, you can see that Editable Mesh contains five sub-objects: Vertex, Edge, Face, Polygon, and Element, while Editable Poly contains Vertex, Edge, Border, Polygon, and Element.


Before entering the sub-object, we observe the two modified tab bars, we can see that the Subdivision Surface tab in Editable Poly (as shown in Figure 01) is not available in Editable Mesh. This tab is mainly used to perform the entire polygon object Subdivision. In the previous version, we can only add another smooth modification to see the results of the segmentation.


In the Selection rollout, four selection buttons have been added to Editable Poly (as shown in Figure 02), which can improve efficiency when selecting sub-objects. In the Edit Geometry rollout, each sub-object of Editable Mesh. The commands that appear when they are selected are placed in this rollout.


The Edit Geometry rollout in Editable Poly only stores the commands for the overall control of the polygon. When the polygon sub-object is selected, the corresponding rollout bar will appear, and the rollout bar stores the sub-objects to be used. Commands, such as when we enter the Vertex (point) level, the Edit Vertices rollout will appear.


It is not difficult to see that Editable Polygon occupies a very large advantage, it is the first choice for building complex models, and it is also the object we will focus on, and from the perspective of software developers, it should also focus on the function of Editable Polygon.


Note: Editable Polygon cannot be directly assigned to geometry as a modification command. Instead, you can only select a geometry first and then collapse it into Editable Polygon. Specific operation: Right-click in the lower blank of the modified stack list, and select Editable Polygon from the menu.
