Why features transform sketches into 3D solids in Solidworks - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a 3D solid from a 2D sketch using the correct feature.

Solidworks

feature = model.[1](sketch)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using Sketch instead of Extrude

Using Dimension which only sizes sketches

The Extrude feature transforms a 2D sketch into a 3D solid by extending it along a direction.

medium

Complete the code to specify the direction for the extrusion feature.

Solidworks

feature.setDirection([1])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Choosing parallelToSketch which does not create thickness

Using sketchPlane which is a plane, not a direction

The extrusion direction is set normalToSketch to extend the sketch into 3D space.

3fill in blank

hard

Fix the error in the feature creation by selecting the correct method to add thickness.

Solidworks

feature = model.[1](sketch).setThickness(10)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using Cut or Fillet which do not create solids

Using Sketch which only defines 2D geometry

The Extrude feature is used to add thickness and create a 3D solid from a sketch.

4fill in blank

hard

Fill both blanks to create a revolved 3D solid from a sketch around an axis.

Solidworks

feature = model.[1](sketch).setAxis([2])

Drag options to blanks, or click blank then click option'

ARevolve

BExtrude

CaxisLine

DsketchPlane

💡 Hint

Common Mistakes

Using Extrude which does not revolve

Using sketchPlane as axis which is a plane, not a line

The Revolve feature creates a 3D solid by rotating the sketch around an axisLine.

5fill in blank

hard

Fill all three blanks to create a lofted solid between two sketches with a guide curve.

Solidworks

feature = model.[1]([sketch1, sketch2]).setGuideCurve([2]).setStartCondition([3])

Drag options to blanks, or click blank then click option'

Ctangent

DExtrude

💡 Hint

Common Mistakes

Using Extrude which works with one sketch only

Not setting a guide curve for complex shapes

The Loft feature creates a solid between sketches using a guideCurve1 and a tangent start condition for smooth transition.
