When working with arcs in AutoCAD, you can use different methods to draw them. The given exhibit shows a dimensioned arc which looks to be defined by three points: the starting point, the center point, and the ending point. This is typically how the "Start, Center, End" method works.
* Start Point: The initial point where the arc begins.
* Center Point: The center of the circle from which the arc is a segment.
* End Point: The final point where the arc ends.
This method is useful for accurately defining the curve and ensuring it passes through the desired points.

* Set DVIEW Twist Angle:
* Type DVIEW in the command line and press Enter.
* Select the object (or type TW for Twist).
* Enter 37 for the twist angle.
* Set SNAPANG Value:
* Type SNAPANG in the command line and press Enter.
* Enter 37 for the snap angle.
* Verify UCS Alignment:
* Ensure the UCS icon is aligned parallel to the A-B rotation line.
* Draw the building relative to the aligned UCS.

Explanation
The offset command is used to create parallel lines, concentric circles, and parallel curves1. To use the offset command, you need to specify the offset distance and select the object that you want to offset23.

Explanation
array items are contained in a single array object, similar to a block. You can change the number of these items and their spacing in an associative array.
Based on 2, you can move an item in an associative array by pressing and holding the Ctrl key, and then selecting the items you want to move.
since explode is the command that separates objects into individual objects. Disassociate, ungroup and break are not valid commands for associative arrays.
