In Onshape, where is the main toolbar located within the primary interface?
Right side panel
Top of the window
Which action rotates the 3D view in Onshape?
Right-click and drag

Which description correctly explains Onshape’s origin?
The center point (0,0,0) for all sketches
Only used in drawings, not models
Which set lists Onshape’s standard reference planes?

Which AutoCAD command opens the dialog to set Decimal, Architectural, and Precision units?
DIMSTYLE command for dimensions
UNITS command for unit setup
In Onshape, where do you set inch, millimeter, and degree units for sketches?

What is the default input mode for the CIRCLE command described in the study guide?
Center and Radius specification
Three-point circle selection
Which keyboard function key in AutoCAD locks cursor movement to horizontal and vertical directions only?
F8 Ortho for axis locking
F3 Osnap for snapping
What does F3 (Osnap) primarily help with when drafting in AutoCAD?
Toggling orthographic movement
Snapping to endpoints, midpoints, centers
During the Onshape sketching process, which step or action orients the view normal to the selected plane?
Press 'N' to set view normal
Enable 'Ortho' for normal view
Which Onshape constraint makes two points occupy the exact same location?
Coincident constraint for shared point
Concentric constraint for same center
Which constraint ensures a circle and an arc share the same center in Onshape?
Concentric constraint for common center
Equal constraint for same radius

In Onshape, which constraints force geometry to be perfectly straight along axes?
Vertical and Horizontal constraints
Perpendicular and Parallel constraints
What is the recommended workflow for dimensions in Onshape sketches?
Dimension before drawing geometry

What does blue geometry indicate during Onshape sketching?
Undefined sketch can still change
Suppressed and invisible
What is the desired end state for Onshape sketches before creating features?
Partially constrained shapes

Which AutoCAD modify command creates parallel lines or concentric circles at a set distance?
OFFSET for parallel geometry
COPY for duplicating shapes
What does the TRIM command accomplish in AutoCAD?
Extends a line to a boundary edge

In AutoCAD, what is the primary distinction between MOVE and COPY?
MOVE duplicates; COPY repositions
MOVE repositions; COPY duplicates
In AutoCAD, which command creates a reflected copy across a defining line?
SCALE changes overall size
MIRROR makes a symmetric reflection
What does the AutoCAD FILLET command do when given a radius?
Rounds a sharp corner between edges
Extends lines to meet boundaries
How are Layers used in AutoCAD drawings?
They render photorealistic textures
They organize lines by color or type
Which Onshape feature turns a 2D sketch into a 3D solid by pushing it?
Revolve around a defined axis line
Extrude from a closed sketch profile
In Onshape, which feature spins a profile around an axis to create a part?
Revolve produces rotational geometry
