Question

Which axis is not used when working in 2-D frame?

(a) Z-axis

(c) X-axis

(d) WCS

The question was asked by my college director while I was bunking the class.

I'm obligated to ask this question of Computer Aided Drafting in division Nomography, Computer Aided Drafting & Procedure of Estimating of Civil Engineering Drawing

Answer 1

Correct choice is (a) Z-axis

Easy explanation: The User Coordinate System defines

• The XY plane, also called the work plane, on which objects are created and modified

• The horizontal and vertical directions used for features like Ortho mode, polar tracking, and object snap tracking

• The alignment and angle of the grid, hatch patterns, text, and dimension objects

• The origin and orientation for coordinate entry and absolute reference angles

• For 3D operations, the orientation of work planes, projection planes, and the Z axis for vertical direction and axis of rotation

You can change the location and orientation of the current UCS by clicking the UCS icon and using its grips, or with the UCS command.

 Display options for the UCS icon are available with the UCSICON command.
