Wall Commands

WALL

WALL <coord1 [{LEFT|CENTERED|RIGHT}] <coord> ENTER> ENTER

This command builds a wall along a polyline defined by its nodes. With the switch 'LEFT/RIGHT/CENTERED ' you can place the wall's axis on the left (LEFT) or on the right (RIGHT) side of the reference line, or place the axis on it (CENTERED). If the last point coincides with the first the polyline will be closed.

coord1 (point): the first node of the wall

coord (point): one corner of the wall

e.g.: WALL 10 0 CENTERED 10 10 20 10 20 0 10 0;;

-It creates four walls with the length of 10, forming a square. The left bottom corner of the reference line is located at (10,0) and the wall's axis is placed at the reference line.

POLYGON

WALL POLYGON <<coord> ENTER> ENTER

It builds a wall along the contour of a polygon. The polygon is defined by its vertices and the last is automatically connected with the first. The axis of the wall always lies on the reference line.

coord (point): one vertex of the polygon

e.g.: WALL POLYGON 10 0 10 10 20 10 20 0;;

-It creates four walls with the length of 10, forming a square. The left bottom corner of the reference line is located at (10,0).

RECTANGLE

WALL RECTANGLE <$rect_def$ ENTER> ENTER

It creates a wall along the contour of a rectangle. The outer perimeter of the wall will always be located at the reference line.

$rect_def$: the definition of a rectangle. For the details see the chapter: Definitions

e.g.: The following commands results the same:

#WALL RECTANGLE 10 0 20 0 15 10;

#WALL RECTANGLE HV 10 10 20 0;

#WALL RECTANGLE WIDTH 10 10 0 INVERSE 20 0;

-It creates four walls with the length of 10, forming a square. The left bottom corner of the reference line is located at (10,0).

SPOLYGON

WALL SPOLYGON <st_point [{LEFT | CENTERED | RIGHT}] $polyline_def$> ENTER

It creates a wall along a series of straight lines, circular arcs and splines. With the switches LEFT, CENTERED and RIGHT you can set the wall's axis lying left to, right to or on the reference line. The line won't be closed automatically.

st_point (point): the first point of the polyline

$polyline_def$: the definition of a polyline. See it in the chapter: Definitions

CHAIN

WALL CHAIN <chain> ENTER

It creates a wall from a closed chain. The chain has to be created before by 2D object creating commands. The wall's axis runs always inside the chain. The existing objects won't be deleted they remain part of the drawing.

chain (obj):  a chain the wall's  reference line will be created from

e.g.: #POLYGON 10 0 20 0 20 10 10 10; #WALL CHAIN 15 0;

-It creates four walls with the length of 10, forming a square. The left bottom corner of the reference line is located at (10,0).

OPENCHAIN

WALL OPENCHAIN <chain> ENTER

It creates a wall from a chain which can be either closed or open. The chain has to be created before by 2D object creating commands. The wall's axis runs always inside the chain. The existing objects won't be deleted they remain part of the drawing.

chain (obj):  a chain the wall's reference line will be created from

e.g.: #LINE 10 0 20 0 20 10 10 10; #WALL CHAIN 15 0;

-It creates 3 perpendicular walls. One from (10,0) to (20,0), the second from (20,0) to (20,10) and the last from (20,10) to (0,10).

ONEBYONE

WALL ONEBYONE <line> ENTER

It creates a wall from a closed chain. The chain has to be created before by 2D object creating commands.  You have to select the pats of the chain one by one in a sequential order. The wall's axis runs always inside the chain. The existing objects won't be deleted they remain part of the drawing

line(obj): a part of the chain

e.g.: #LINE 10 0 20 0 20 10 10 10 10 0; #WALL ONEBYONE 15 0 20 5 15 10 0 5;

-It creates four walls with the length of 10, forming a square. The left bottom corner of the reference line is located at (10,0).

INRECT

WALL INRECT <coord> ENTER

It creates a wall from a closed chain. The chain has to be created before by 2D object creating commands. You can select the change by its one internal point. The wall's axis runs always inside the chain. The existing objects won't be deleted they remain part of the drawing

coord: an internal point of the chain

e.g.: #LINE 10 0 20 0 20 10 10 10 10 0; #WALL INRECT 15 5;

-It creates four walls with the length of 10, forming a square. The left bottom corner of the reference line is located at (10,0).
