Hi,

This is an example of how to get the System Variable OSMODE.

 Autodesk.AutoCAD.ApplicationServices.Application.GetSystemVariable("OSMODE");

You can get this values using the DataBase object.

For example, if you want to use the precision lenght:

Database db = HostApplicationServices.WorkingDatabase;
int precision = db.Luprec;

Hello,

do you know how to set the rest of the UNITS variables. Direction of base angle to be NORTH, and angle to be calculated CLOCKWISE, to be specific. Thank you.

Best regards,

ANGBASE & ANGDIR

Re: Get Variables set by Units command

Thank you, but this is what I get when I set ANGBASE to 90, and ANGDIR to 1.

This "Rotacija" property is my custom atribute that just reads rotation property from Block Reference entity and displays it in decimal value. It still shows value respect to AutoCAD's original angle direktion which is East. Seems like under the hood nothing changed.

The BlockReference.Rotation property is always measured in radians counterclockwise from the X axis of the block reference OCS (while the block reference normel is equal to Z Axis, the OCS is the same as WCS).

You can convert the BlockReference.Rotation value to a clockwise positve decimal degrees value starting from north doing:

double degrees = (450.0 - blockReference.Rotation * 180.0 / System.Math.PI) % 360.0;

Another way, if the ANGBASE and ANGDIR sysvars are correctly set, is to use the Converter.AngleToString() method.

Thank you very much. I was looking at the problem the wrong way trying to get the CAD behave like I want. Instead I have to adapt to it's behaviour.
