constructing a circle tangent to a line and another circle, with the same cursor position. The key can be
used for switching between these two configurations.
Similarly, during editing, a circle configuration can be flipped as well.
Let’s review each way of constructing circles in details.
Various Ways of Constructing Circles
Begin with setting the option:
Tab
Select a node as the circle center
,
This combination creates a circle with the center in the selected node and the radius defined by either placing
the cursor and clicking or entering an exact value in the property window or parameters dialog box (the
option ). To create this type of a circle, point the cursor at the desired node and click . The node will
be highlighted, and a circle with the center in this node will start rubberbanding. The circle can then be fixed
manually, by clicking , or exactly, by specifying the radius value in the property window or parameters
dialog box.
,
This combination creates a circle with the center at a specified node, and tangent to another circle. Move the
cursor to an existing node or use the option for creating a node at the nearest intersection of
construction entities. Click . This results in rubberbanding a circle with the center in the selected node.
Move the cursor to a circle to become the tangency reference for the one being created, and type . The
required circle will be created. Two different configurations are possible, depending on where on the tangent
circle the cursor was pointing at the time of entering the option.
