CAD Workflow and Productivity Flashcards

What does PDM (Product Data Management) software do in a CAD workflow?

Answer: Manages version control, access rights, and storage of CAD files across a team

PDM systems track revisions, control check-in/check-out of CAD files, and maintain a single source of truth for design data across engineering teams.

What is an external reference (XREF) in CAD, and why is it used?

Answer: A drawing file attached to the current drawing that updates automatically when the source file changes

XREFs allow multiple drawings to reference a common base file (such as a floor plan) so all dependent drawings update automatically when the base is modified.

Which keyboard shortcut is universally used in most CAD applications to repeat the last command?

Answer: Spacebar or Enter

Pressing the Spacebar or Enter after completing a command re-invokes the most recent command, speeding up repetitive drafting tasks.

In a CAD drawing, what is the purpose of a title block?

Answer: To record drawing metadata such as title, revision, scale, drafter name, and date

The title block provides essential administrative information about the drawing, ensuring traceability and compliance with drafting standards.

What is the benefit of enabling Object Snap (OSNAP) in CAD drafting?

Answer: It snaps the cursor precisely to key geometric points like endpoints, midpoints, and intersections

OSNAP forces the cursor to attach to specific geometric features, eliminating manual coordinate entry errors and ensuring accurate construction.

What does the term 'drawing revision' mean in a CAD workflow?

Answer: An updated version of a drawing that documents changes made after initial release

A revision is a formally controlled update to a released drawing, tracked with a revision letter or number in the title block and a revision history table.
