3D Designing a Custom Handle Using SelfCAD
3D modeling in construction is transforming how projects are designed, planned, and executed. In the production phase, 3D models are essential for making things like door furniture with high precision. CNC machines and other automated tools use the detailed 3D model to create parts accurately. This may minimize waste and keep the quality of the products consistent.
Steps of Creating a Door Handle in SelfCAD
In this section, we are looking at how you can create the door handle using the basic shapes, and modify them using Extrusion macros to form the desired shape. You will also see how to change the materials and colors, as you refine the object. Start by launching SelfCAD and open the workspace:
The first step is creating the escutcheon. Select the Cube from the 3D Shapes:
Set the parameters of the cube as shown below:
Tick the check mark to finalize the cube. The next step is making the edges of the cube smoother. Activate the Edge Selection tool from the right side panel, and from the Modify category, select the Fillet Tool:
Set the Intensity to 1 and the Level to 5:
Tick the check mark to finalize the the Fillet. From the 3D Shapes select the Cylinder and set the parameters as shown below:
Tick the checkmark to finalize the cylinder. Select the two meshes and on the toolbar, select Stitch and Scoop. Choose Difference and select the cylinder mesh to remove it:
Set the Keep Subtracted Object to true then tick the check mark to finalize the difference:
The next step si to create the handle itself. From the 3D Shapes select the Cylinder and set the parameters as follows:
Tick the check mark to finalize the cylinder. Select the two cylinders, and on the toolbar, select Stitch and Scoop> Difference. Choose the latest cylinder to subtract it:
Set the Keep Subtracted Object to true:
Tick the check mark to finalize the difference. Activate the Polygon Selection on the right side panel, and select the highlighted region. Select the Extrusion tool from the Modify category:
Set the Extrusion Amount to 1. On the Advanced Settings click Add Option and set the operation to Rotate. Set Y to -5 and the Repeat to 18:
Tick the check mark to finalize the extrusion. Select the Extrusion from the Modify category again:
Set the Extrusion amount to 100:
Tick the check mark to finalize the extrusion. Activate the Edge Selection from the right side panel, and click on the gear icon. Set the Loop Selection to true and use it to select the edges as shown below:
On the toolbar, select Fillet from the Modify category:
Set the Fillet Intensity to 4.9 and Level to 10:
Tick the check mark to finalize Fillet. Select all the objects, and select Materials from the right side panel. Set the Material type to Physical materials:
Click on the Color button, and select the White color and click ok to confirm the color:
Set the Metalness to 0.6 and Roughness to 0.4:
Tick the check mark to finalize the materials. There you go, the simple metallic door handle is ready:
Using extrusion macros in SelfCAD makes designing a door handle and other models quicker and easier. This tool works by automating repetitive steps, so you can focus on the details. We started by creating the basic shape of the handle, then used macros to refine and finish the design. This tool saves time and, ensures accuracy, and creates high-quality door handles with less effort. After 3D modeling, you can use the in-built online slicer of SelfCAD to slice your files and generate the G-code to send to your 3D printer.
Enjoy powerful modeling, rendering, and 3D printing tools without the steep learning curve.
