AutoCAD Case Studies & Practical Application 3 — Questions and Answers
Question 1: An interior designer is laying out furniture in a room drawn at 1:50 scale in model space. A sofa block is 2200mm long in reality. How long should it appear in model space?
- 44mm
- 2200mm (Correct answer)
- 110000mm
- 22mm
Correct answer: 2200mm
Model space is always drawn at full real-world size (1:1); scale is applied at the viewport or plot stage, so the sofa is drawn 2200mm long.
Question 2: A project requires that all new walls be drawn on a layer named 'A-WALL' with color Red and linetype Continuous. How do you enforce this standard across a 10-person team?
- Email the layer settings to each team member
- Use a shared DWT template with the layer predefined and distributed via CAD Standards (DWS) file (Correct answer)
- Rely on each drafter to create the layer manually
- Use the AUDIT command to add layers
Correct answer: Use a shared DWT template with the layer predefined and distributed via CAD Standards (DWS) file
A DWT template combined with a DWS standards file enforces layer names, colors, and linetypes and flags violations with CAD Standards Check.
Question 3: After receiving an updated site plan as an XREF, a designer notices the attached file shows outdated geometry. What is the correct action?
- Detach and reattach the XREF
- Use XREF Manager to Reload the reference (Correct answer)
- Explode the XREF and update manually
- Copy new geometry from the original file
Correct answer: Use XREF Manager to Reload the reference
Reloading an XREF in the External References Manager refreshes it with the latest saved version of the source file.
Question 4: A plumbing engineer needs to show a hidden pipe run beneath a floor slab. Which layer property combination is correct?
- Color: White, Linetype: Continuous
- Color: Cyan, Linetype: HIDDEN or DASHED (Correct answer)
- Color: Red, Linetype: CENTER
- Color: Green, Linetype: PHANTOM
Correct answer: Color: Cyan, Linetype: HIDDEN or DASHED
Hidden or dashed linetypes conventionally represent objects that are concealed behind or beneath other elements.
Question 5: A landscape architect wants to hatch a planting area but the hatch bleeds outside the boundary. What is the most likely cause?
- The hatch scale is too large
- The boundary polyline has gaps or is not fully closed (Correct answer)
- The hatch pattern is wrong
- The layer is frozen
Correct answer: The boundary polyline has gaps or is not fully closed
Hatch requires a fully closed boundary; gaps cause it to flood beyond the intended area.
Question 6: A client asks for a 3D perspective view of a building model exported as an image for a presentation. Which sequence is correct?
- Set a camera with CAMERA or 3DORBIT, then use JPGOUT or BMPOUT to export the current view (Correct answer)
- Use PLOT to print the 3D view to a printer
- Run RENDER then save with SAVEAS as DWG
- Use SECTION to cut the model then export
Correct answer: Set a camera with CAMERA or 3DORBIT, then use JPGOUT or BMPOUT to export the current view
Setting a perspective camera and then exporting with JPGOUT (or using EXPORT > image formats) captures the current 3D view as a raster image.
Question 7: A drafter accidentally deleted 12 objects and has since performed 5 other edits. How should the drafter recover just those 12 objects without losing the later work?
- Close without saving and reopen the file
- Use UNDO multiple times until the objects return, redo the 5 edits
- Use OOPS to restore the last deleted set without affecting other edits (Correct answer)
- Run AUDIT to recover deleted objects
Correct answer: Use OOPS to restore the last deleted set without affecting other edits
OOPS restores only the most recently erased objects without undoing any subsequent commands.
