🖊️ Spline
Creates a smooth curve through specified points.
Command: SPLINE or SPL
Usage:
Enter SPLINE, specify the first fit point.
Add successive fit points.
Optionally close the spline or define tangent directions.
Ideal for designing smooth, free-form curves.
✱ Xline (Construction Line)
Draws an infinite line through two points.
Command: XLINE or XL
Usage: Pick two points—line extends infinitely beyond them.
Great for creating alignment guides or grid layouts.
➛ Ray
Creates a semi-infinite line starting at one point and extending through another.
Command: RAY
Usage:
Define the start point, then a through point.
Press Enter to stop.
Useful for directional reference lines.
◼️ Divide
Evenly places point markers (or blocks) along an object without modifying it.
Command: DIV or DIVIDE
Usage:
Select the object.
Specify the number of segments.
Automatically places points representing divisions.
📏 Measure
Places points or blocks at fixed interval spacing along an object.
Command: MEASURE
Usage:
Select object.
Set the interval distance.
Marks equal-length intervals without splitting the object.
🧱 Region
Transforms closed loops into region objects—a filled 2D area.
Command: REGION or REG
Usage: Select closed paths (like polylines or circles).
Regions can be used for calculations (e.g., area), extrusions, and Boolean operations.
❌ Wipeout
Covers parts of a drawing with a background mask without deleting objects.
Command: WIPEOUT
Usage:
Draw a polygonal boundary or convert an existing closed polyline.
Optionally disable frame visibility via the Frame option.
Useful for hiding details behind text or simplifying annotations.
🌀 Spiral (Helix)
Generates a 2D or 3D spiral (helix) shape.
Command: HELIX
Usage:
Typically found under Draw → Helix, or via the HELIX command line.
Useful for springs, threads, or 3D modeling.
🍩 Donut
Draws a filled circle or ring (donut-shaped).
Command: DONUT or DO
Usage:
Specify the inside diameter (0 for a filled circle).
Specify the outside diameter.
Pick center point(s).
Result is a closed polyline with thickness.
☁️ Revision Cloud
Creates a cloud-like polyline to highlight revisions.
Command: REVCLOUD
Usage:
Freehand or convert existing closed shapes into a cloud.
Optionally adjust arc spacing via Arc length.
Typically used to emphasize modified areas in drawings.
