# Step-by-Step Solution for SolidWorks Model (Part 6) Let's break down the model creation based on the provided drawing and dimensions. --- ## 1. **Setting Up the Units** - Open SolidWorks. - Set the **Unit System** to **MMGS** (millimeter, gram, second). --- ## 2. **Sketch the Base** ### a. **Create the Outer Base** 1. **Front Plane** → **Sketch**. 2. Draw a **rectangle** with rounded corners (fillet radius = 20 mm). - **Overall size:** 200 mm (width) x 100 mm (height). - Add corner fillets of **20 mm**. ### b. **Extrude the Base** - **Extrude Boss/Base**: Set thickness to **30 mm**. --- ## 3. **Sketch the Inner Base** 1. **Top face of the base** → **Sketch**. 2. **Inner rectangle**: 170 mm x 70 mm (calculated as 200-2×15 by 100-2×15). - Add corner fillets of **15 mm**. 3. **Extrude**: **30 mm** (this creates the step). --- ## 4. **Create the Vertical Boss** ### a. **Sketch the Upright Section** 1. **Front plane** → **Sketch**. 2. Draw a **rectangle**: 100 mm (width) x 130 mm (height). - Centered on the base (so 50 mm on each side of the base center). - The bottom of this rectangle should sit on top of the upper base (thus, the bottom is at Z = 60 mm from the part origin). 3. Add a **semicircle** (radius 100 mm) on top of the rectangle (so the total height = 130 mm rectangle + 100 mm semicircle = 230 mm, but the drawing shows only 160 mm total height from the base step up). - Adjust the center of the semicircle to be at the top of the rectangle. - The overall height from the bottom (including both steps) is **160 mm**. ### b. **Extrude the Boss** - **Extrude**: **30 mm** (to match the thickness in the side view). --- ## 5. **Add the Hole** 1. **Front face of vertical boss** → **Sketch**. 2. Draw a **circle** of diameter **100 mm**. - Centered horizontally and vertically in the upper portion. 3. **Extruded Cut**: Through all. --- ## 6. **Add Fillets** - Add **edge fillets** of **10 mm** to the two front top corners of the boss (as indicated by R10 X2). --- ## 7. **Apply Material** - **Right-click part → Material → Copper**. - Set **Density:** .0089 g/mm³ (if needed). --- ## 8. **Check Decimal Places** - Go to **Document Properties → Units** and set decimal places to **3**. --- ## 9. **Final Checks** - **Verify dimensions** match the drawing. - The part origin as per the drawing should be at the center of the bottom face. --- # **Summary Table of Dimensions** | Feature | Dimension (mm) | |---------------------|---------------| | Base (outer) | 200 x 100 | | Base (inner step) | 170 x 70 | | Base thickness | 30 | | Vertical boss width | 100 | | Vertical boss height| 160 | | Boss thickness | 30 | | Hole diameter | 100 | | Corner fillets | 20 (base), 15 (step), 10 (boss) | --- ## **Your Final Part Should Look Like This:** - Two-stepped rectangular base with filleted corners, - Vertical boss with a large central hole, - All dimensions and fillets as specified. --- **This step-by-step guide will help you build the part in SolidWorks as per the provided drawing.
