Dimension placement and annotation in Solidworks - Dashboard Guide

Dashboard Mode - Dimension placement and annotation

Goal

Understand how to place and annotate dimensions clearly in a SolidWorks drawing to communicate design intent effectively.

Sample Data: Dimensions and Annotations

Feature	Dimension Type	Value	Annotation Text
Base Length	Linear	150 mm	Length of base
Base Width	Linear	80 mm	Width of base
Height	Linear	100 mm	Overall height
Hole Diameter	Diameter	10 mm	Mounting hole
Angle	Angular	45°	Inclination angle
Radius	Radius	20 mm	Fillet radius

Dashboard Components

• KPI Cards: Show key dimension values with annotations for quick reference.
  Example: Base Length: 150 mm (Length of base)
• Dimension Placement Diagram: A simplified drawing image showing dimension lines placed outside the part edges with leader lines pointing to features.
  Formula: Use standard SolidWorks dimension placement rules to avoid overlap and maintain clarity.
• Annotation Table: Lists all annotations with their corresponding dimension and feature.
  Formula: Filter annotations by dimension type or feature for focused review.

Dashboard Layout

+----------------------+----------------------+----------------------+  
|      KPI Cards       | Dimension Placement  |   Annotation Table   |  
|  (Top left corner)   |    (Center area)     |   (Right side)       |  
+----------------------+----------------------+----------------------+  
|                      Filters: Dimension Type (Linear, Angular, Diameter, Radius)                      |  
+----------------------------------------------------------------------------------------------------+  

Interactivity

Filters allow selecting dimension types (e.g., Linear, Angular). When a filter is applied:

• KPI Cards update to show only dimensions of the selected type.
• Dimension Placement Diagram highlights only the filtered dimensions on the drawing.
• Annotation Table lists annotations only for the filtered dimensions.

Self Check

If you add a filter for Diameter dimensions, which components update and how?

• KPI Cards: Show only the Hole Diameter dimension with value 10 mm and annotation 'Mounting hole'.
• Dimension Placement Diagram: Highlight only the hole diameter dimension line and leader.
• Annotation Table: Display only the annotation for Hole Diameter.

Key Result

Dashboard showing dimension values, placement visualization, and annotations filtered by dimension type in SolidWorks drawings.

Practice

1. What is the main purpose of placing dimensions on a SolidWorks drawing?

easy

A. To change the color of the drawing lines

B. To show exact sizes and measurements of parts

C. To add decorative elements to the drawing

D. To hide parts of the drawing

Solution

1. Step 1: Understand the role of dimensions

   Dimensions provide exact sizes and measurements needed to make or inspect parts.

2. Step 2: Differentiate from other drawing elements

   Decorations or colors do not communicate size; dimensions do.

3. Final Answer:

   To show exact sizes and measurements of parts -> Option B

4. Quick Check:

   Dimensions = Exact sizes [OK]

Hint: Dimensions always show sizes, not decoration or color [OK]

Common Mistakes:

• Confusing dimensions with decorative drawing elements
• Thinking dimensions change drawing colors
• Assuming dimensions hide parts

2. Which of the following is the correct way to place a dimension in SolidWorks?

easy

A. Place a text box anywhere on the drawing

B. Draw a freehand line and write the size manually

C. Use the paint tool to highlight the size

D. Click the dimension tool, select two points, then place the dimension line

Solution

1. Step 1: Identify the correct dimension placement method

   In SolidWorks, you use the dimension tool to select points or edges to measure.

2. Step 2: Understand why other options are incorrect

   Freehand lines, paint tools, or text boxes do not create accurate dimensions.

3. Final Answer:

   Click the dimension tool, select two points, then place the dimension line -> Option D

4. Quick Check:

   Dimension tool + points = correct placement [OK]

Hint: Always use the dimension tool, not freehand or text [OK]

Common Mistakes:

• Trying to draw dimensions manually
• Using paint or text tools for dimensions
• Not selecting points before placing dimension

3. Given a rectangular part with length 100 mm and width 50 mm, what will the dimension annotation show if you select the two opposite corners along the length?

medium

A. 50 mm

B. Length can't be measured between corners

C. 100 mm

D. 150 mm

Solution

1. Step 1: Identify the points selected

   Two opposite corners along the length measure the full length of the rectangle.

2. Step 2: Recall the length value

   The length is given as 100 mm, so the dimension will show 100 mm.

3. Final Answer:

   100 mm -> Option C

4. Quick Check:

   Opposite corners length = 100 mm [OK]

Hint: Measure between opposite corners for full length [OK]

Common Mistakes:

• Confusing length with width
• Adding length and width by mistake
• Thinking corners can't be measured

4. You placed a dimension but it shows an incorrect value. What is the most likely cause?

medium

A. You selected the wrong points or edges for the dimension

B. The drawing color is incorrect

C. The annotation font size is too small

D. The part is hidden in the drawing

Solution

1. Step 1: Analyze why dimension value is wrong

   Dimension values depend on the points or edges selected; wrong selection causes wrong values.

2. Step 2: Exclude unrelated causes

   Color, font size, or hidden parts do not affect dimension values directly.

3. Final Answer:

   You selected the wrong points or edges for the dimension -> Option A

4. Quick Check:

   Wrong points = wrong dimension [OK]

Hint: Check points selected if dimension value looks wrong [OK]

Common Mistakes:

• Blaming color or font for wrong dimension
• Ignoring point selection errors
• Assuming hidden parts cause wrong dimension

5. You need to add an annotation explaining a special surface finish on a part. Where should you place this annotation for best clarity?

hard

A. Near the surface it describes, without overlapping dimensions

B. Anywhere on the drawing, even if it covers dimensions

C. Only in the title block of the drawing

D. Inside the part model, hidden from view

Solution

1. Step 1: Understand annotation placement principles

   Annotations should be close to the feature they describe and not block important information.

2. Step 2: Evaluate options for clarity

   Placing annotations near the surface and avoiding overlap keeps the drawing clear and readable.

3. Final Answer:

   Near the surface it describes, without overlapping dimensions -> Option A

4. Quick Check:

   Clear, close, no overlap = best annotation placement [OK]

Hint: Place annotations close and clear, avoid covering dimensions [OK]

Common Mistakes:

• Placing annotations randomly over dimensions
• Putting annotations only in title block
• Hiding annotations inside the model
