DESCRIBE
Shows how each expression is defined, rather than what it comes to: an element as the statement that makes it, a point or a variable as the expression it is defined by.
Syntax
DESCRIBE expression,expression,…
| Argument | Meaning |
|---|---|
| expression | Any expression, such as an element (@1), a point (P2) or a variable (L). |
Examples
L=300,"Length"
P2=[L,L/2]
LINE @1,P0,P2,0
DESCRIBE @1,P2,L,DISTANCE(P0,P2)/2
shows, in the Interactive window:
@1 → LINE @1,P0,P2,0 |
The element, as the statement that draws it. |
P2 → [L,L/2] |
The point's definition. |
L → 300,"Length" |
The variable's expression, and its label. |
DISTANCE(P0,P2)/2 → DISTANCE(P0,P2)/2 |
Any other expression, as it is written. |
Notes
Each argument is shown as expression → definition in ParametrIQ CAD's Interactive window and in
the playground, as PRINT shows values. Nothing is worked out and nothing changes, so
DESCRIBE shows how a drawing is built: what a point follows, which points an element is drawn on. To see what an
expression comes to, use PRINT or type the expression on its own. The
Identify Tool and the Properties panel show an element's definition too.
