Understanding the purpose of Sketch Trim

What is the main purpose of the Sketch Trim tool in SolidWorks?

A To extend sketch lines to meet other sketch entities automatically.

B To create new sketch entities based on existing ones.

C To remove unwanted portions of sketch entities by cutting them at intersections or boundaries.

D To convert 3D models into 2D sketches.

💡 Hint

Think about how you clean up a drawing by cutting off extra parts.

The Sketch Trim tool is used to remove unwanted parts of sketch lines or curves by trimming them at intersections or boundaries.

Difference between Trim and Extend

Which statement best describes the difference between the Sketch Trim and Sketch Extend tools in SolidWorks?

A Trim lengthens sketch entities; Extend removes parts of sketch entities.

B Trim and Extend are the same tool with different names.

C Both Trim and Extend remove parts of sketch entities but in different directions.

D Trim removes parts of sketch entities; Extend lengthens sketch entities to meet other entities.

💡 Hint

Think about cutting versus stretching lines.

Trim cuts away parts of sketch entities, while Extend lengthens them to meet other sketch entities.

Calculating Trimmed Line Length in a Sketch

Given a sketch with multiple lines, which DAX measure correctly calculates the total length of lines after trimming unwanted segments stored in a 'SketchLines' table with columns 'LineID', 'Length', and 'IsTrimmed' (TRUE if trimmed)?

A TotalTrimmedLength = SUMX(FILTER(SketchLines, SketchLines[IsTrimmed] = TRUE()), SketchLines[Length])

B TotalTrimmedLength = CALCULATE(SUM(SketchLines[Length]), FILTER(SketchLines, SketchLines[IsTrimmed] = TRUE()))

C TotalTrimmedLength = CALCULATE(SUM(SketchLines[Length]), SketchLines[IsTrimmed] = TRUE())

D TotalTrimmedLength = SUM(SketchLines[Length]) - CALCULATE(SUM(SketchLines[Length]), SketchLines[IsTrimmed] = TRUE())

💡 Hint

Use FILTER inside SUMX to sum only trimmed lines.

SUMX with FILTER correctly sums lengths of lines where IsTrimmed is TRUE. CALCULATE with a filter expression requires FILTER function for row context.

Best Visualization for Sketch Trim and Extend Usage

Which visualization best helps a user understand the frequency of using Sketch Trim versus Sketch Extend tools across multiple projects?

A A stacked bar chart showing counts of Trim and Extend tool usage per project.

B A pie chart showing the percentage of Trim and Extend usage combined across all projects.

C A line chart showing the trend of total sketch entities over time.

D A scatter plot showing the length of trimmed lines versus extended lines.

💡 Hint

Think about comparing two categories across projects.

A stacked bar chart clearly shows the counts of each tool's usage per project side by side, making comparison easy.

Debugging Sketch Extend Calculation Error

A DAX measure to calculate total extended line length is written as:

TotalExtendedLength = CALCULATE(SUM(SketchLines[Length]), SketchLines[IsExtended] = TRUE)

This measure returns an error. What is the cause?

Solidworks

TotalExtendedLength = CALCULATE(SUM(SketchLines[Length]), SketchLines[IsExtended] = TRUE)

A The column name 'IsExtended' is invalid and causes the error.

B The filter expression must be wrapped inside FILTER function to create a row context.

C SUM cannot be used inside CALCULATE; SUMX should be used instead.

D The filter expression inside CALCULATE must use TRUE() function, not TRUE without parentheses.

💡 Hint

CALCULATE requires filter expressions to be valid Boolean filters or wrapped in FILTER.

Using 'SketchLines[IsExtended] = TRUE' directly inside CALCULATE causes an error because it is not a valid filter expression. Wrapping it inside FILTER creates the proper row context.
