what is the difference between wcs and ucs in autocad

by Bonnie Greenfelder Published 3 years ago Updated 3 years ago

What is the difference between WCS and UCS in AutoCAD? The UCS (User Coordinate System) is the system in which you are working. By default, it is located to coincide with the WCS, but it can be moved. The World Coordinate System (WCS) is the internal, high accuracy (10 digits) and absolute coordinate system. Click to see full answer.

The coordinates of the world coordinate system(WCS) define the location of all objects and the standard views of AutoCAD drawings. However, WCS are permanent and invisible. It cannot be moved or rotated. AutoCAD provides a movable coordinate system called the user coordinate system(UCS).

How do I change from WCS to UCS in AutoCAD?

One may also ask, how do you change WCS to UCS in AutoCAD? To make WCS active, type UCS and hit return twice (or rightclick on ucsicon and choose WCS). To move your objects to the WCS origin, turn on, unlock, and thaw all layers.

What is the difference between the UCS and the WCS?

The UCS (User Coordinate System) is the system in which you are working. By default, it is located to coincide with the WCS, but it can be moved. The World Coordinate System (WCS) is the internal, high accuracy (10 digits) and absolute coordinate system.

Is WCS horizontal or vertical in AutoCAD?

Normally in 2D views, the WCS X axis is horizontal and the Y axis is vertical. One may also ask, how do you change WCS to UCS in AutoCAD?

What is the first point of UCS in AutoCAD?

The move command's first point should be 0,0,0. Herein, what is a UCS in AutoCAD? The UCS is a moveable Cartesian coordinate system that establishes the XY work plane, horizontal and vertical directions, axes of rotation, and other useful geometric references.

What is the origin of a WCS drawing?

The WCS origin is where the X and Y axes intersect (0,0). All objects in a drawing file are defined by their WCS coordinates. However, it is usually more convenient to create and edit objects based on the movable UCS. By default when you start a new (blank) drawing you use the World Coordinate System (WCS).

How to rename a UCS?

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.) Click OK. You can use up to 255 characters, including letters, digits, and the special characters dollar sign ($), hyphen (-), and underscore (_).

What does it mean when you move the UCS origin?

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.

How to move UCS?

You can relocate the user coordinate system with methods such as the following: 1 Move the UCS by defining a new origin point. 2 Align the UCS with an existing object. 3 Rotate the UCS by specifying a new origin point and a point on the new X axis. 4 Rotate the current UCS a specified angle around the Z axis. 5 Revert to the previous UCS. 6 Restore the UCS to be coincident with the WCS.

What is the world coordinate system?

The World Coordinate System is based on the Cartesian Coordinate System. Having an understanding of this coordinate system (which many people have, despite of probably never heard of the name) is essential to understanding how the WCS (and UCS) work within AutoCAD.

Differentiate Between Ucs And Wcs In Autocad

Cable Scheduler: Fixed creation of a loop in the view of a cable route when the route in the CS database has fewer segments than in Cableroute.dbf. Cable Scheduler: Fixed problem that single termination wires from schematic drawings were deleted and recreated each time CS was started.

Difference Between Ucs And Wcs

New Features. AutoCAD 2017 support. GstarCAD 2016 support. Cable Scheduler: Create model-less cable routes (raceway segments and routes created directly in the Cable Scheduler database). Assign cables to model-less routes and get length and filling information.

User coordinate system (UCS): The working coordinate system. The user specifies a UCS to make drawing tasks easier. All points passed to AutoCAD commands, including those returned from AutoLISP routines and external functions, are points in the current UCS (unless the user precedes them with an * at the Command prompt).

Change The Ucs In Autocad

Paper space DCS: This coordinate system can be transformed only to or from the DCS of the currently active model space viewport. This is essentially a 2D transformation, where the X and Y coordinates are always scaled and offset if the Disp argument is FALSE. The Z coordinate is scaled but never translated.

This example creates a polyline in model space. The first vertex for the polyline is then displayed in both the OCS and WCS coordinates. The conversion from OCS to WCS requires the normal for the OCS be placed in the last argument of the TranslateCoordinates method.
