3D CAD - Exercise 1

Exercise 1

Features used

In this CAD tutorial we'll use the features: 

1. Extrude (PAD) feature : Transform 2d sketch in a solid body.

2.Extruded cut (POCKET) feature: removes material from the part.

All dimensions are in mm/g/s/ISO

Here is the 3D model: you can interact with it, zoom in, rotate, and explore it to better understand all the details.

2D Sketch

Tutorial: CAD CAM Creating a Model in SOLIDWORKS 2025

Objective: Create a simple model with an extrusion and a hole using basic SOLIDWORKS tools.

Step 1: Create the Initial Sketch

1. Open SOLIDWORKS and start a new part document.

2. Select the Front Plane:

   • Go to the Sketch tab and click on Front Plane.

3. Draw the basic profile:

   • Use the Line tool to create the outline of the shape.

4. Add dimensions to the sketch:

   • Use the Smart Dimension tool to set:

     • 8 mm for the bottom width.

     • 100 mm for the total length.

     • 25 mm for the side heights.

       
       

Step 2: Create the Extrusion

1. Exit the sketch by clicking Exit Sketch.

2. Go to the Features tab and select Extruded Boss/Base.

3. Set the extrusion parameters:

   • Direction: Select Mid Plane.

   • Distance: Enter 50 mm.

4. Click OK to complete the extrusion.

   
   

Step 3: Add the Hole

1. Select a flat face of the part to create the hole sketch.

2. Draw the circle:

   • Go to Sketch and select Circle.

   • Place a circle at the center of the face.

3. Dimension the circle:

   • Use Smart Dimension to define:

     • Diameter: 20 mm.

     • Distance from the top edge: 55 mm.

4. Set relations:

   • Select the center of the circle and the midpoint of the base line.

   • Use Add Relation to make the relation Vertical.

   
   

Step 4: Create the Cut

1. Exit the circle sketch.

2. Go to the Features tab and select Extruded Cut.

3. Set the cut parameters:

   • Direction: Choose Through All.

4. Click OK to finalize the cut.
