Practical feature of 3D software: part design!

Thread Content

Computer-aided design software (CAD software) is a core tool for research, development, and design, with 3D design software being the cornerstone among them. Part design, assemblies, sheet metal design, and engineering drawings are the most frequently used elements in a mechanical engineer’s daily work. This means that the experience and efficiency in these aspects of 3D software have a significant impact on a company’s research, development, and design capabilities. As an important part of part design, solid modeling refers to the process of creating a 3D representation of an object, that is, by constructing basic solids and adding or removing material through the creation of features to form the final shape of the part. So how can engineers, in their actual work, truly achieve rapid idea presentation or modification of historical data, thereby enabling simple operations and easy use? Let me introduce it to you all now! How to design parts? The part design in HaoChen 3D is consistent with that of components in mainstream 3D design software; the basic steps include drawing shapes, adding material, removing material, modifying features, and adding attributes. Step 1: Before drawing the shapes, select a sketch plane in the software’s model space; use the X-Y plane as the bottom of the part, and this plane can be locked using F3. Taking the “Create Matrix from Center” command as an example, by clicking on a center point and a corner to draw a rectangle, the software will create a closed rectangle. The width and length can be entered directly; the handles can be used to control the direction of stretching (one-way or two-way) as well as the extent of the stretching, or precise dimension values can be entered using the keyboard. Step 2: Based on the first feature surface, sketch the outline of the next feature, and then determine its height by stretching it as well. When creating a boss on the top of the part, be careful to use contours drawn on the same plane to determine the directions in which it should be pulled, so that it passes through the rectangular post and extends outward. Add triangular fasteners, sketch with the center of the part as the plane; at this point, symmetrical addition of material on the left and right can be achieved by selecting and stretching the two sides. Step 3: Use the hole command to create a 10-mm hole that passes through the boss; add holes to the base plate in the same way, and the holes can be symmetrically distributed on both sides of the part using the mirror command. Chamfering is used to remove material from corners, and the chamfer radius can be entered and adjusted immediately. That’s all for the tutorial on part design in HaoChen 3D software.
