GetPt3D

Description

Procedure GetPt3D switches the cursor to 3D selection mode and allows the user to select a point in a VectorWorks document. This cannot be used if there is a function anywhere in the calling chain.

PROCEDURE GetPt3D(
				VAR pX, pY, pZ : REAL;
				useWPOnly      : BOOLEAN);
def vs.GetPt3D(useWPOnly, callback):
    return None

Parameters

Name Type Description
pX, pY, pZ REAL Returns coordinates of mouse click.
useWPOnly BOOLEAN TRUE if the returned point have to be on the active Working Plane. Snapping to arbitrary 3D geometry will produce vertical projection result on the WP; FALSE if the point can be arbitrary 3D point (produced, for example, by snapping to a 3D geometry)

Remarks

(_c_, 2011.01.09) the z-value of the returned 3D point is always zero if

  • the current view is Top-plan or Top (From Raymond Mullin).
  • there is no pre-existing snapped geometry in 3D (by useWPOnly = FALSE)

In Python this function will NOT block execution. It will execute a callback function with the resulted point (as callback function parameter).

Examples

on sample is similar to the sample in GetPt.

BEGIN
	DSelectAll;
	GetPt3D( pt.x, pt.y, pt.z, TRUE );
	h := CreateCustomObjectN( 'HumanFigure', pt.x, pt.y, 0,False );
END;

BEGIN
	IF ResourceIsOK THEN
	GetOrigin(origin.x, origin.y);
	SetOriginAbsolute(0, 0);
	GetPt3D(pt1.x, pt1.y, pt1.z, false);
	{GetPt(pt1.x, pt1.y);}
	crit := '(R IN [''Space''])';
	polyCnt := Count(crit);
	{ AlrtDialog(CONCAT('Space Link Tool: polyCnt = ', polyCnt)); }

SetOriginAbsolute(0,0);
GetPt3D( x, y, z, FALSE );
SetOriginAbsolute(xOrg,yOrg);

def handle_object(objHandle):
    vs.Message('Processing: ' + str(objHandle))

useWPOnly = True
callback = handle_object

vs.GetPt3D(useWPOnly, callback)
