Differentiate Between Ucs And Wcs In Autocad

Working in a UCS and not the WCS. The block come in rotated according to the WCS which means it is not rotated accordingly in the current UCS. Is there a way to automatically populate/determine the ThisDrawing.ModelSpace.InsertBlock command with the rotation angle that is the 'difference' between the WCS and UCS? Changing From UCS to WCS in AutoCAD. This workflow could be useful for Corridor projects or mapping that was received by outside. Agencies (Cities. Could somebody explain to me the differences between the UCS and WCS please.? In particular the (trans (0 0 0) 0 1) and (trans (0 0 0) 1 0).

You can relocate the user coordinate system with methods such as the following:

• Move the UCS by defining a new origin point.
• Align the UCS with an existing object.
• Rotate the UCS by specifying a new origin point and a point on the new X axis.
• Rotate the current UCS a specified angle around the Z axis.
• Revert to the previous UCS.
• Restore the UCS to be coincident with the WCS.

Each of these methods have a corresponding option in the UCS command. Once you have defined a UCS, you can name it and then restore it when you need to use it again.

For instance: If you want to set a drawing to a newly determined zero-point, so you can use that particular point as the starting point for a coordinate system you need to use, you can just move the UCS to that new point. That point will then be the (0,0,0) point. You can even change the UCS angle if that is required. You can name them and save them, so you can switch between them. In Paperspace you need to keep in mind that the UCS only has a (0,0) point: An ‘X' and a ‘Y' coordinate.

When moving the UCS origin (see pictures below) you can see the square in the crosshairs is gone, meaning you use the User Coordinate System. Instead of seeing WCS underneath your compass you now see ‘Unnamed', meaning your active UCS is still unnamed.

To save your newly determined UCS do the following:

Ucs In Autocad

1. Click View tab>UCS panel>Named UCS. The new UCS is displayed in the UCS list as UNNAMED.
2. In the UCS dialog box, Named UCSs tab, select UNNAMED and enter a new name. (You can also select UNNAMED, and right-click. Click Rename.)
3. Click OK. You can use up to 255 characters, including letters, digits, and the special characters dollar sign ($), hyphen (-), and underscore (_). All UCS names are converted to uppercase.

When you have determined a new UCS origin, and want to switch back to the World Coordinate System, you need to save you new UCS before you switch. Otherwise the new point UCS point will be lost.

There is much, much more to say about the UCS system, but these things are just the basics. Of course the command to use to manipulate your UCS is:

This will give you all sorts of options (to move, rotate, name, etc.) for your UCS.
