CSWA - Certified Solidworks Associate 2D Sketching and Relations Questions and Answers

Question 1

When sketching in SolidWorks, you notice that a sketch is displayed in red and yellow colors, and the status bar indicates 'Over Defined'. What is the most likely cause?

Accepted Answer

Conflicting or redundant dimensions and/or geometric relations have been applied.

Answer

An 'Over Defined' sketch occurs when there are duplicate or conflicting dimensions and relations. This redundancy provides too much information, and SolidWorks cannot solve the sketch. The red and yellow colors are visual indicators of this conflict.

Question 2

In a 2D sketch, you need to ensure that a circle and a line touch at only a single point, without crossing. Which geometric relation should you apply between the two entities?

Accepted Answer

Tangent

Answer

The 'Tangent' relation is used to make two curved entities or a line and a curved entity touch at a single point without intersecting. A 'Coincident' relation would place the line on the circle's circumference, and 'Concentric' applies to two circles sharing a center point.

Question 3

What is the primary purpose of using 'Construction Geometry' (e.g., a centerline) in a SolidWorks sketch?

Accepted Answer

To serve as a reference for creating other sketch geometry, without being part of the final feature profile.

Answer

Construction geometry, which appears as dashed lines, is used for reference purposes only. It helps in creating and constraining the main sketch geometry (solid lines) but is ignored when a sketch is used to create a 3D feature like an extrude or revolve.

Question 4

A user is creating a sketch for a part. After adding all dimensions and relations, all sketch lines turn black. What does this color indicate about the sketch's state?

Accepted Answer

The sketch is fully defined and has no unconstrained degrees of freedom.

Answer

In SolidWorks' default color scheme, black sketch entities indicate that the sketch is 'Fully Defined'. This is the desired state, meaning every entity's position and size is locked by dimensions and relations, preventing accidental changes. Blue indicates 'Under Defined'.

Question 5

Which of the following relations requires three selections to apply: two sketch entities and a centerline?

Accepted Answer

Symmetric

Answer

The 'Symmetric' relation requires selecting two entities (like points or lines) and a centerline. It makes the two entities equidistant from the centerline, creating a mirror-like relationship across it.
