Understanding the Revolved Boss/Base Feature

Which statement best describes the purpose of the Revolved Boss/Base feature in SolidWorks?

A It creates a 3D solid by revolving a 2D sketch around an axis.

B It extrudes a 2D sketch linearly to create a solid.

C It creates a surface by lofting between multiple sketches.

D It applies a fillet to the edges of a solid body.

💡 Hint

Think about how a 2D shape can be turned into a 3D object by spinning it around a line.

The Revolved Boss/Base feature takes a 2D sketch and spins it around a chosen axis to form a 3D solid. This is useful for creating symmetrical parts like cylinders or cones.

Calculating Volume of a Revolved Solid

You have a table with a column 'Radius' and a column 'Height' representing a cylinder created by revolving a rectangle. Which DAX measure correctly calculates the volume of this cylinder?

A Volume = SUMX(Table, PI() * Table[Radius]^2 + Table[Height])

B Volume = SUMX(Table, 2 * PI() * Table[Radius] * Table[Height])

C Volume = SUMX(Table, PI() * Table[Radius] * Table[Height]^2)

D Volume = SUMX(Table, PI() * Table[Radius]^2 * Table[Height])

💡 Hint

Recall the formula for the volume of a cylinder: π × radius² × height.

The correct formula for the volume of a cylinder is π times radius squared times height. Option D correctly applies this formula in DAX using SUMX to calculate the total volume.

Best Visualization for Revolved Boss/Base Dimensions

You want to create a dashboard showing the distribution of revolved part volumes and their heights. Which visualization type best communicates this information clearly?

A A pie chart showing the count of parts by volume ranges.

B A scatter plot with Volume on the Y-axis and Height on the X-axis.

C A stacked bar chart showing total volume by height categories.

D A line chart showing volume changes over time.

💡 Hint

Think about how to show the relationship between two numeric variables.

A scatter plot is ideal to show how volume and height relate for each part, allowing you to see patterns or clusters. Pie charts and stacked bars are less effective for two continuous variables.

Modeling Revolved Part Data for Analysis

You have multiple tables: Parts, Dimensions, and Materials. To analyze revolved boss/base parts, which relationship setup is best?

A Create a one-to-many relationship from Parts to Dimensions using PartID, and a many-to-one from Materials to Parts using MaterialID.

B Create a many-to-many relationship between Parts and Dimensions, and no relationship with Materials.

C Create a one-to-many relationship from Dimensions to Parts, and a one-to-one from Materials to Parts.

D Create no relationships and use LOOKUPVALUE in measures.

💡 Hint

Consider how parts relate to their dimensions and materials in real life.

Each part can have multiple dimensions, so Parts to Dimensions is one-to-many. Each part has one material, so Materials to Parts is many-to-one. This setup supports efficient analysis.

Debugging a Revolved Boss/Base Volume Calculation

Given this DAX measure to calculate volume of revolved parts, what error will it produce?

Volume = SUMX(Parts, PI * Parts[Radius]^2 * Parts[Height])

A No error; the measure calculates volume correctly.

B TypeError because Parts[Radius] is not a number.

C SyntaxError because PI is used without parentheses.

D Runtime error due to missing aggregation on Height.

💡 Hint

Check how the PI constant is used in DAX.

In DAX, PI is a function and must be called with parentheses: PI(). Using PI without parentheses causes a syntax error.
