[.NET] Align Object with Plane

179 Views, 2 Replies

Hello !

 

For one of our project, we have a very precise scanner that picks 3 points on a material to generate a plane.

(First point is always (0,0,0))

 

On autocad, I have to align different object with this plane.

 

I'd like to know if there is a method to directly align object with this plane?

(I can easily have the normal to this plane, and other informations, if needed)

 

We already try to calculate angles and make a rotation, but it's not very accurate.

 

Thanks for help !

 

Best regards,

Hi,

 

Not sure if a direct method exists, this is really specific. Anyway, the Matrix3d struct is the base for all those changes, have you looked at Matrix3d.WorldToPlane method? It can be a start point.

Hello. Thanks for your answer !

 

Finally, i've found the command "3DALIGN" that do exactly what I want. It's not "automatic", but our custommer is happy with that.

 

Thanks again.
