Understanding Sketch Fillet Purpose

What is the main purpose of using a sketch fillet in a CAD sketch?

A To create a rounded corner between two sketch lines for smooth transitions.

B To create a sharp corner by extending one line beyond another.

C To add a straight chamfered edge between two lines.

D To mirror a sketch entity across an axis.

💡 Hint

Think about how corners look when they are smoothed out.

A sketch fillet rounds the corner between two lines, making the transition smooth and curved.

Difference Between Fillet and Chamfer

Which statement correctly describes the difference between a sketch fillet and a sketch chamfer?

A Fillet extends lines; chamfer shortens lines.

B Fillet creates a straight angled cut; chamfer creates a rounded corner.

C Both fillet and chamfer create rounded corners but with different radii.

D Fillet creates a rounded corner; chamfer creates a straight angled cut.

💡 Hint

Think about the shape of the corner after applying each tool.

A fillet rounds the corner with an arc, while a chamfer cuts the corner at an angle creating a straight edge.

Calculating Number of Fillets in a Sketch

Given a sketch with multiple corners, you want to calculate how many fillets have been applied. Which DAX expression correctly counts the fillet features in the 'SketchFeatures' table where 'FeatureType' equals 'Fillet'?

Solidworks

COUNTROWS(FILTER(SketchFeatures, SketchFeatures[FeatureType] = "Fillet"))

A COUNTROWS(FILTER(SketchFeatures, SketchFeatures[FeatureType] = "Fillet"))

B COUNT(SketchFeatures[FeatureType] = "Fillet")

C SUMX(SketchFeatures, IF(SketchFeatures[FeatureType] = "Fillet", 1, 0))

D CALCULATE(COUNT(SketchFeatures[FeatureType]), SketchFeatures[FeatureType] = "Fillet")

💡 Hint

Use FILTER to select rows, then COUNTROWS to count them.

Option A filters the table for fillet features and counts the rows correctly. Option A syntax is incorrect for CALCULATE filter. Option A works but is less efficient. Option A is invalid syntax.

Best Visualization for Fillet and Chamfer Usage

You have data on how many fillets and chamfers are used in different sketches. Which visualization best shows the comparison of fillet vs chamfer counts across sketches?

A A line chart showing fillet counts over time only.

B A pie chart showing total fillets and chamfers combined.

C A clustered bar chart showing fillet and chamfer counts side by side for each sketch.

D A scatter plot with fillet counts on X-axis and chamfer counts on Y-axis.

💡 Hint

Think about how to compare two categories across multiple items clearly.

A clustered bar chart allows side-by-side comparison of fillet and chamfer counts per sketch, making differences easy to see.

Debugging Chamfer Calculation Error

You have this DAX measure to calculate total chamfers:
TotalChamfers = COUNTROWS(FILTER(SketchFeatures, SketchFeatures[FeatureType] = "Chamfer"))
But it returns zero even though there are chamfers in the data. What is the most likely cause?

A The COUNTROWS function cannot be used with FILTER in this context.

B The 'FeatureType' column contains extra spaces or different casing like ' chamfer' or 'Chamfer '.

C The SketchFeatures table is empty.

D The measure syntax is invalid because of missing CALCULATE.

💡 Hint

Check the exact text values in the 'FeatureType' column.

If the 'FeatureType' values have extra spaces or different letter cases, the filter condition will fail to match, causing zero results.
