3D Exercise 130

Exercise 130

In this CAD tutorial we'll use the features: 

1. Extrude

Instead of sketching the entire symmetrical footprint of a part, you only sketch one half of it, ending exactly on the origin or a center reference plane.

• The Strategy: You extrude this half-profile into a solid body. By building only half the part, you keep the initial sketch incredibly simple, reducing the number of dimensions and constraints needed, which makes the file more stable and easier to edit later.

2. Fillet

Here is where the efficiency of this workflow really shines. You apply all your necessary edge treatments to that single half-body.

• Function: You add structural fillets to internal corners for stress relief and cosmetic fillets to the outside edges.

• The "Why": By applying the fillets now, before the mirror command, you only have to click half as many edges. When the part is eventually mirrored, all of these edge treatments will be automatically duplicated to the other side.

3. Mirror

This is the final step that completes the solid model.

• Function: You select the entire half-body (or the specific Extrude and Fillet features in your timeline) and mirror it across that center plane where your initial sketch ended.

• Mechanism Application: This guarantees that the left and right sides of your bracket or joint are mathematically identical. If you ever need to change a dimension or adjust a fillet radius, you only change it on the original half, and the mirrored half updates instantly.

All dimensions are in mm/g/s/ISO
