If You Want To Do A Good Job Of Product Reverse Discount, The Inspection Method Is Very Important

We have to check whether the designed product or part has undercuts during the design process and when it is completed. Now I will share with you 3 methods for checking undercuts.

1. Use 【Slope Analysis】to check the undercut. If there is a red surface in the blue surface area, an undercut will appear, or if a blue surface appears in the red surface area, an undercut will appear, as shown in the figure below.

2. As shown in the figure below, if there is a red side in the blue side area, there will be an undercut, and if there is a blue side in the red side area, there will be an undercut.

3. Use 【Check Area】to check the undercut. See if there are faces in the undercut area, as shown in the image below.

4. Click the [Surface] interface, select [Undercut Area] to view the undercut position, as shown in the figure below.

5. Check the undercut with [Wireframe with faded edges]. First [Preferences] - [Visualization Preferences] set the color of the hidden geometry to a more conspicuous color, such as red, as shown in the figure below.

6. Arrange the product along the direction of the row position, and use the view of the wire frame with faded edges to observe whether there is a red line. If there is no red line, it means that the row position has no undercut, as shown in the figure below.

7. Arrange the front mold core along the direction of the front and rear mold core ejection, and use the view of the wire frame with faded edges to observe whether there is a red line. A red line indicates that the front mold core still has an undercut, and the structure must be removed. ,As shown below.
