REVOLVE

REVOLVE generates a surface of revolution, which is described by a polyline defined in the XY plane rotating about the X axis. Arcs and segments can be defined within the polyline by using additional status code values.

Syntax

REVOLVE n, alpha, mask, x1, y1, s1, ... , xn, yn, sn

Parameters

n (integer): number of polyline nodes

alpha (decimal, in degrees): rotation angle

mask: controls the existence of the bottom, top and - in case of alpha is < 360 degrees - cut surfaces (see below)

xi, yi (decimal): X and Y coordinates of the polyline nodes

si (boolean): with si = -1 holes are defined directly

parameter restrictions: n ³ 2; yi ³ 0; yi and y(i + 1) (i.e., the Y coordinate of two adjacent nodes) cannot be zero at the same time

Masking

mask = j1 + 2*j2 + 4*j3 + 8*j4

with j1, j2, j3, j4 may be 0 or 1
j1 (1): bottom surface is present
j2 (2): top surface is present
j3 (4): cut surface at initial angle is present
j4 (8): cut surface at final angle is present

Remarks

Usable since script version 1.1 (Allplan 2012-1).
