14.2.2. Relative Coordinate System

Try these first

1. 1.

   What is the format for entering relative coordinates in CAD?

   Hint

   Remember to use the '@' symbol.

2. 2.

   If you are at point (2,3) and move to @4,5, where do you end up?

   Hint

   Add the relative movements to the last point.

3. 3.

   What symbol is used to indicate relative coordinates in CAD?

   • @
   • #
   • $

   Hint

   Think about how CAD inputs specify different types of coordinates.

4. 4.

   True or False: The Relative Coordinate System requires you to specify coordinates based on the origin point.

   • True
   • False

   Hint

   Consider the difference between absolute and relative positions.

5. 5.

   You are designing a layout that requires several cuts in a structure. Starting at point (0,0), you first go @3,2. From there, you turn and move @1,-4, then again @-3,3. What final coordinates do you arrive at?

   Hint

   Trace through each move carefully from one point to the next.

6. 6.

   During a drafting session, you draw an initial rectangle starting at point (0,0) to @5,0 and then up to @0,4, before finishing to the left @-5,0. If you then add another rectangle starting from the last corner, how would you define the position of the first corner of the new rectangle in relative coordinates?

   Hint

   Keep in mind the relationship of the starting point when initiating a new shape.
