Hello everyone!

How to obtain coordinates of a point shifted along axis of a given Datum CSYS? For example, of a point with coordinates 0,0,0 shifted along the Z-axis at a distance of 100. Obviously it would be 0,0,100 but what is the program method? Datum CSYS can be oriented at random angles so simply adding values won't work. I suspect that I should somehow use matrix transformation + csys methods, but I couldn't work it out. Can you please help?

A wrapper method exist for csys to csys.

Public Sub CsysToCsys (

from_origin As Double(),

from_x_axis As Double(),

from_y_axis As Double(),

to_origin As Double(),

to_x_axis As Double(),

to_y_axis As Double(),

mtx As Double())

Hello,

I am not sure. To obtain the coordinates of DatumCsys, you can use features.Location property if the featuretype is DatumCsys. To edit/move the DatumCsys coordinates, use CreateXform method.

Thanks.
