Create a LWPolyline on an UCS that is not World

Hi,

I am trying to create a 2d polyline on the side of a rectangle. My problem
is I know the coordinates of the new polyline that I need to add in its own
ucs. I use the Utility.TranslateCoordinates method to find those
coordinates in the world ucs, my problem, however has to do with only being
able to enter X and Y coordinates into the array defining the LWPolyline.
Depending on the UCS, this may be Y and Z, X and Z, or something different
than that. How do I accomplish this? Any ideas are greatly appreciated.

 

You need to adjust the drawing so you are always drawing X and Y or use
a regular polyline that accepts 3D input.

Thanks for your quick reply Mike. I am not sure I understand your comment
"adjust the drawing so you are always drawing X and Y". What do you mean by
this? Are you saying do not draw, for example, a YZ polyline?

I changed the object type that I am adding to model space to 3dPolyline. It
worked as I had hoped. The AddPolyline method takes input of X, Y, and Z,
however Help states that the Z is ignored. This is why I just tried the
3dPolyline. When I list the newly created geometery, it lists as a
polyline, which should be fine. The geometry is being processed further by
CAM software and I dont think there will be an issue with Polyline VS
LWPolyline.

I really appreciate your help. By changing to 3DPline, things seem to be
working fine.

Thanks again.

 

Are you saying do not draw, for example, a YZ polyline?
Yes, an LWPOLYLINE *only* accepts X and Y because it is 2D. You need o
adjust the UCS and view so you are always drawing in PLAN.

No problem! ~ Mike
