Translate coordinates troubles.

R2005 Vlisp:

From the help files:

To translate a point on a Polyline or LightWeightPolyline object from OCS to WCS:

1. Get the X and Y coordinates of the OCS point from the Coordinate or Coordinates property.

2. Get the Z coordinate of the OCS point from the Elevation property.

3. Get the Normal for the polyline from the Normal property.

4. Call TranslateCoordinates using the X, Y, Z coordinates and the Normal.

Okay, the list of coordinates has the z value because its a 3dpoly I'm gettting this from. But when I try to use:

Command: (vla-TranslateCoordinates (list 21.8651 1.36718 0.0) norm_1)
; error: bad argument type: VLA-OBJECT (21.8651 1.36718 0.0)

I've tried making the pointa vlax-3d-point with no luck.

norm_1 is the normal object.

Command: !norm_1
#<variant 8197 ...>

TIA

Bill,
First, when using the ActiveX methods you must supply a response to all
arguments.
Second, the "TranslateCoordinates" method is applicable to what object? This
is the root of the error you are getting.
This is why I include these in my startup files:
(setq *acad* (vlax-get-acad-object)
*doc* (vla-get-activedocument *acad*)
*util* (vla-get-utility *doc*))

This is the form you must use:
(vla-translatecoordinates *util* (vlax-3d-point (list 21.8651 1.36718 0.0))
acOCS acWorld :vlax-false norm_1)

HTH,

Jeff,

It was the Utility that threw me.

Thanks.
