Understanding Sketch Plane Selection Basics

In SolidWorks, when you start a new sketch, you must select a plane or planar face. Which of the following best describes why selecting the correct sketch plane is important?

A It determines the orientation and position of the sketch in 3D space.

B It automatically creates 3D features without further input.

C It locks the sketch so it cannot be edited later.

D It changes the color of the sketch entities.

💡 Hint

Think about how the sketch relates to the rest of the 3D model.

The sketch plane sets where and how the sketch lies in 3D space, which affects how features are created from it.

Choosing the Right Plane for a New Sketch

You want to create a hole on the top face of a box-shaped part. Which plane or face should you select to start your sketch for the hole?

A Any plane will work the same.

B The front plane of the part.

C The right plane of the part.

D The top planar face of the box.

💡 Hint

Consider where the hole will be located on the part.

To place a hole on the top face, you must start the sketch on that top planar face to ensure correct positioning.

Calculating Sketch Count per Plane

Imagine a BI report tracking the number of sketches created on each plane in SolidWorks. You have a table 'Sketches' with columns 'SketchID' and 'PlaneName'. Which DAX measure correctly counts sketches per plane?

Solidworks

SketchCount = CALCULATE(COUNTROWS(Sketches), ALLEXCEPT(Sketches, Sketches[PlaneName]))

A SketchCount = DISTINCTCOUNT(Sketches[PlaneName])

B SketchCount = SUM(Sketches[SketchID])

C SketchCount = CALCULATE(COUNTROWS(Sketches), ALLEXCEPT(Sketches, Sketches[PlaneName]))

D SketchCount = COUNTROWS(Sketches)

💡 Hint

Think about counting sketches grouped by plane.

Option C counts sketches per plane by removing filters except on PlaneName, giving correct counts per plane.

❓ visualization

Best Visualization for Sketch Plane Usage

You want to create a dashboard showing how many sketches are created on each plane over time. Which visualization type best shows this trend clearly?

A Line chart showing sketches count per plane over months.

B Stacked bar chart showing sketches per plane for a single month.

C Scatter plot showing sketch IDs versus plane names.

D Pie chart showing total sketches per plane.

💡 Hint

Consider which chart best shows changes over time.

A line chart clearly shows trends over time for each plane's sketch count.

Debugging Sketch Plane Selection Issue

A user reports that when they select a plane to start a sketch, the sketch appears rotated incorrectly. What is the most likely cause?

A The selected plane is not planar but curved.

B The sketch was started on a plane with a different orientation than expected.

C The software version is outdated and has a bug.

D The sketch entities were drawn before selecting the plane.

💡 Hint

Think about how plane orientation affects sketch appearance.

If the plane orientation differs from what the user expects, the sketch will appear rotated relative to the model.
