Offset command

[Dieter @ DWorks]

Hi, is there some sort of offset command in vectorscript? i can find one, so please help me. I need to offset a polygon.

See HDuplicate.

[Dieter @ DWorks]

that's not the same! HDuplicate duplicates the original object and moves it, but I need to offset the original so it is bigger

Sorry...I didn't understand.

Apparantly there is an undocumented function that has been used successfully by some:

OffsetPoly

Declaration

FUNCTION OffsetPoly (h: HANDLE; dist: REAL; repeat: INTEGER; a: BOOLEAN; b: BOOLEAN, accuracy: INTEGER; c: REAL;): HANDLE;

Description

Currently Undocumented Function, Given a handle to a polyline draws a offset Polyline with distance dist and returns a handle to the new polyline.

The following info is incomplete

Parameters

h Handle to the polyline to offset from

dist distance of offset

repeat number of repeat offsets

a unknown, has something to do with accuracy

b unknown, has something to do with Polyline or Polygon creation

accuracy increases the number of vertices

c unknown

Function Result to new offset poly or a group containing the offset polys.

Example

NewPathHd:= OffsetPoly(LNewObj, dist, number, FALSE, TRUE, 50, 1);

Comment

"FALSE, TRUE, 50, 1" are the "experimentally verified recommended" values.

A plugin using this function: Frame

This MIGHT work on your object. This info comes from

http://vcor.net/wiki/index.php/Main_Page

Search for 'Offest' or 'Frame' and you can see an example of it in use. Failing this you're probably going to have to write your own.

Maybe this will help
