1. What concept is the key to drawing on any face in 3D?
The zoom
The UCS (User Coordinate System)
Layer 0
The hatch
In 3D, you draw on the XY plane of the current UCS: orienting it lets you draw anywhere. Navigation: orbit, ViewCube, visual styles.
2. How is a 3D solid most often created?
Keyboard only
By transforming a closed 2D profile (extrusion, revolve…)
With a hatch
With a layer
Extrude, revolve, sweep, loft, then boolean operations (union, subtract/drill, intersect). The profile must be closed.
3. What is the point of generating 2D views from a 3D model?
None
The views are associative: they update with the model
It's slower
It removes the 3D
« Model once, document automatically » (BASEVIEW). Rendering (materials, lights) produces presentation images.
4. What does a dimensional constraint drive (parametric drawing)?
The color
A dimension via a value or a formula (e.g. width = 2 × height)
The layer
The print scale
You draw the INTENT: changing a parameter adjusts the whole geometry. Geometric constraints (parallel…) are maintained automatically.
5. What is AutoLISP used for?
To print
To create your own commands and automate repetitive tasks
To georeference
To dimension
You can load (APPLOAD) existing routines without coding, then write your own. Aliases (PGP), CUI and palettes also speed you up.
