Working with coordinates - Using xyz point filters

Using point filters in two dimensions

You can use point filters when you work in two dimensions to locate points in relation to existing entities. For example, to draw a circle centered in a rectangle, start the Circle command, and then respond to the prompts as follows:

2Point · 3Point · RadTanTan · Arc · Multiple · <Center of circle>: .y

Select Y of: mid

Snap to midpoint of: (select the left side of the rectangle)

Still need XZ of: mid

Snap to midpoint of: (select top of the rectangle)

Diameter · <Radius>: (specify radius of circle)
  1.  
  2.  
     

    You can use point filters to center the circle by separately selecting the midpoints of two sides of the rectangle ( A and B ) and then specifying its radius.
