Units all messed up?

[Wilf.Chun]

Hello, when i try to create any civil 3D objects the default values seem to be out by 1000, for example when trying to create an intersection all the curb return offset values default to 3,000m instead of 3.0m (3,000mm) 

This is also the case when creating profiles or sections all the text defaults to 2500m rather than the expected 2.5.

any suggestions would be appreciated.

If possible could you post a drawing and version.

Check your Drawing Settings and be sure the units aren't set to mm. This can happen when you open drawings that were not originally created with Civil 3D. In my area, we see drawings in inches instead of feet and it causes a mistake by a factor of 12.

Hi @Wilf.Chun,

Make a back up of your drawing and try to drag and drop the attached script below to your drawing.

1) rename the attached c3d_m_units.txt to c3d_m_units.scr

2) drag and drop script to sample drawing

;------------------------------------------
; set all units to metres
;------------------------------------------
(setvar "insunits" 6)
(setvar "insunitsdeftarget" 6)
(setvar "insunitsdefsource" 6)
(command "-dwgunits" "6" "2" "3" "n" "n")
(graphscr)
(while (> (getvar"cmdactive") 0)
(command "n")
)
(princ)

This is just to change insunit, source and target to meter and see if it will still make it as 3000m instead of 3m. If you can post your drawing that will be better as more people can help you if you have sample drawing.

Cheers,
