Sketch plane selection in Solidworks - Cell-by-Cell Formula Trace

Sample Data

This table shows features and their associated sketch planes in a SolidWorks model.

Cell	Value
A1	Feature
B1	Plane
A2	Extrude1
B2	Front Plane
A3	Cut1
B3	Top Plane
A4	Boss1
B4	Right Plane

Formula Trace

SELECT Plane WHERE Feature = 'Cut1'

Step 1: Identify row where Feature equals 'Cut1'

Step 2: Return value in column B of Row 3

Cell Reference Map

    A           B
1 | Feature   | Plane     |
2 | Extrude1  | Front Plane|
3 | Cut1      | Top Plane |
4 | Boss1     | Right Plane|

The formula references the 'Feature' column (A) to find 'Cut1' and then returns the corresponding 'Plane' from column B.

Result

    A           B
1 | Feature   | Plane     |
2 | Extrude1  | Front Plane|
3 | Cut1      | Top Plane |  <-- Result: 'Top Plane'
4 | Boss1     | Right Plane|

The result of the formula is 'Top Plane', which is the sketch plane selected for the feature 'Cut1'.

Practice

1. What is the main purpose of selecting a sketch plane in SolidWorks?

easy

A. To add textures to the model surface

B. To change the color of the 3D model

C. To export the model to another file format

D. To define the flat surface where you create 2D sketches

Solution

1. Step 1: Understand sketch plane role

   The sketch plane is the flat surface where you draw 2D shapes that form the base of 3D parts.

2. Step 2: Identify correct purpose

   Changing colors, exporting files, or adding textures are unrelated to sketch plane selection.

3. Final Answer:

   To define the flat surface where you create 2D sketches -> Option D

4. Quick Check:

   Sketch plane = 2D drawing surface [OK]

Hint: Sketch plane is where you draw your 2D shapes [OK]

Common Mistakes:

• Confusing sketch plane with model color or texture
• Thinking sketch plane changes file format
• Assuming sketch plane is a 3D object

2. Which of the following is the correct way to select a sketch plane in SolidWorks?

easy

A. Click on a flat face or a standard plane like Front, Top, or Right

B. Double-click the 3D model to open the sketch

C. Right-click the model and choose 'Add Texture'

D. Drag and drop the sketch onto the model

Solution

1. Step 1: Identify how to pick a sketch plane

   In SolidWorks, you select a sketch plane by clicking a flat face or one of the standard planes (Front, Top, Right).

2. Step 2: Eliminate incorrect methods

   Double-clicking opens sketches but does not select planes; adding textures or drag-drop are unrelated.

3. Final Answer:

   Click on a flat face or a standard plane like Front, Top, or Right -> Option A

4. Quick Check:

   Select plane = click flat face or standard plane [OK]

Hint: Pick flat face or standard plane to start sketch [OK]

Common Mistakes:

• Trying to drag sketches onto models
• Confusing sketch plane selection with texture adding
• Double-clicking does not select plane

3. If you select the Top plane to start a sketch and draw a rectangle, where will the rectangle lie in 3D space?

medium

A. On the vertical plane facing front

B. On the horizontal plane parallel to the ground

C. Floating in mid-air without orientation

D. On the vertical plane facing right

Solution

1. Step 1: Understand the Top plane orientation

   The Top plane in SolidWorks is horizontal and parallel to the ground, representing the 'floor' level.

2. Step 2: Determine rectangle position

   Sketching on the Top plane places the rectangle flat and horizontal in 3D space.

3. Final Answer:

   On the horizontal plane parallel to the ground -> Option B

4. Quick Check:

   Top plane = horizontal floor plane [OK]

Hint: Top plane sketches lie flat like a floor [OK]

Common Mistakes:

• Confusing Top plane with Front or Right planes
• Thinking sketches float without plane
• Assuming vertical orientation for Top plane

4. You tried to start a sketch but the option to select a plane is grayed out. What is the most likely cause?

medium

A. You are in the wrong software

B. Your computer is out of memory

C. You have not selected any face or plane to sketch on

D. The model is locked and cannot be edited

Solution

1. Step 1: Identify why plane selection is disabled

   Sketch plane selection is only enabled when you select a face or a standard plane to start sketching.

2. Step 2: Rule out other causes

   Memory issues or software errors do not specifically disable plane selection; model lock might restrict editing but usually shows a warning.

3. Final Answer:

   You have not selected any face or plane to sketch on -> Option C

4. Quick Check:

   No face selected = plane option disabled [OK]

Hint: Always select a face or plane before sketching [OK]

Common Mistakes:

• Assuming software or memory issues cause grayed options
• Ignoring the need to select a plane first
• Thinking model lock always disables sketching

5. You want to create a sketch on a custom angled plane that is not one of the standard Front, Top, or Right planes. What is the best approach?

hard

A. Create a new reference plane at the desired angle, then select it for sketching

B. Try to sketch directly on the 3D model surface without a plane

C. Use the Front plane and rotate your sketch manually after drawing

D. Export the model and edit the sketch in another software

Solution

1. Step 1: Understand custom plane creation

   SolidWorks allows creating reference planes at any angle or offset to use as sketch planes.

2. Step 2: Choose correct method for angled sketch

   Creating a new reference plane at the desired angle ensures accurate sketch placement; other options are inefficient or incorrect.

3. Final Answer:

   Create a new reference plane at the desired angle, then select it for sketching -> Option A

4. Quick Check:

   Custom angle = new reference plane [OK]

Hint: Make a new angled plane to sketch precisely [OK]

Common Mistakes:

• Trying to sketch without a plane
• Rotating sketches after drawing causes errors
• Using external software unnecessarily
