Xref scaling when using Geolocation markers...

[jpCADconsulting]

Hi folks!

When I try to xref a survey file (units=feet) into our template (drawn units=inches) , everything seems fine. It's seeing the incoming file in feet and scales properly by a factor of 12:

However, as soon as I select "Locate Using Geographic Data", the block unit settings flip to "Feet/1.0000".

Is this just how geolocation works? It assumes everything is always in feet?

Thanks!

@jpCADconsulting ,

Is this just on your computer?

Provide the following information:

INSUNITS =

INSUNITSDEFTARGET = 

INSUNITSDEFSOURCE =

INSBASE = 

DWGUNITS =

Hi Emilio,

It's not just My computer.

In the host file (feet):

INSUNITS = 2

INSBASE = 0,0

DWGUNITS = 2

In the we are trying to xref into it (inches):

INSUNITS = 1

INSBASE = 0,0

DWGUNITS = 1

I assume the since INSUNITS is non zero in both files, INSUNITSDEFTARGET, and INSUNITSDEFSOURCE are ignored.

Surveys are always in feet, its the industry standard (other than meters of course).

Agreed but we draw in inches. When we xref one into the other they scale properly UNLESS we check "Locate Using Geographic Data", then AutoCAD acts like BOTH files are in feet and does not scale the xref properly even when one is in inches.

Emilio, I swapped Host and Xref but you get the idea.

The drawing in feet has correct settings for feet, likewise the drawing in inches.

It actually does not matter which one we xref into which. With "Locate Using Geographic Data" UNCHECKED they scale properly either way and with "Locate Using Geographic Data" CHECKED, AutoCAD seems to assume both files are in feet and does not scale.

@jpCADconsulting ,

Try this suggestion from this link:  Objects are scaled when inserted into a drawing in AutoCAD products (link)

INSUNITS = 0

INSUNITSDEFTARGET = 0

INSUNITSDEFSOURCE = 0

or 

Also, verify the Drawing Unit and GIS Coordinate System within the Geographic Location dialog.

Note: The Coordinate System defines the scale of the map.

Thanks Emilio, that video did the trick!!! I'm a bit of a noob when it comes to geolocation, I did not realize that the map units were separate form the drawing units.

That's a huge help!
