Okay, here is the exact answer to how to change the angle of a drawing in AutoCAD, focusing on changing the view orientation and XY coordinates based on existing geometry, as shown in the reference.
To change the angle or orientation of your drawing view and align the User Coordinate System (UCS) to a specific object or edge in AutoCAD, you typically utilize commands that modify the UCS and subsequently the current view. This allows you to orient your workspace relative to a particular part of your drawing.
One common method, suggested by the provided reference, involves selecting an edge of existing geometry to define the new orientation. This action changes your "top view orientation" and the "X Y coordinates" (UCS) simultaneously or in sequence.
Changing View Orientation and UCS Using an Object
Based on the video reference provided, here is a breakdown of the steps involved:
- Initiate the command: Start the process to change the orientation, likely involving a command related to the UCS or View.
- Select an Edge: As shown in the reference, you will need to "select one edge of the drawing". This edge defines the desired angle and alignment for your new view and UCS.
- Confirm Orientation: After selecting the edge, the reference mentions "And once again click to this orientation." This step might involve confirming your selection or clicking a specific point or control (like on the ViewCube or command options) to indicate you want the view/UCS aligned based on the selected edge.
- Finalize: The process is completed by pressing enter: "And click enter".
As demonstrated in the reference, performing these steps results in: "as you can see guys here my top view orientation is changed and as well as this X Y coordinates."
This process effectively rotates your view and coordinate system so that the selected edge becomes aligned with the horizontal axis (or another defined orientation) in your current view, making it easier to work on elements parallel or perpendicular to that edge.
Why Change the Drawing Angle/Orientation?
Changing the drawing angle or view orientation is useful for several reasons:
- Ease of Drafting: Aligning your view and UCS to a specific part makes it easier to draw new objects parallel or perpendicular to existing geometry without complex calculations.
- Improved Visibility: Getting a "straight-on" view of angled elements simplifies editing and annotation.
- Dimensioning: Dimensioning parallel or perpendicular to rotated objects is much more straightforward when the UCS is aligned.
While the reference demonstrates a specific workflow possibly tied to a particular tool or a sequence of commands (like UCS followed by PLAN), the core idea is to use existing geometry to dictate your workspace orientation.
