, ,
This combination creates a circle of a specified radius, tangent to two
circles. Move the cursor over the first circle and type . Repeat for
the second circle. Then specify the radius – approximately, by clicking
, or exactly, by inputting in the property window or parameters
dialog box (the option ). This type of circle construction is most
plentiful in resulting circle configurations.
Getting the desired one among various tangency types is done by
appropriately positioning the cursor when selecting. In some cases, as,
for instance, in the case of a surrounding circle, an appropriate
selection gets easier when zoomed well out with the command “ZW:
Zoom Window”.
, ,
This combination creates a circle tangent to three lines. Move the cursor over the first line and type .
Repeat for the second and the third line. When selecting the lines, pay attention to the cursor position, which
should be on the side of line intended for the circle location.
, , or , , for constructing a circle tangent to a line and a spline.
, , or , , for constructing a circle tangent to a line and an ellipse.
This combination creates a circle tangent to a line and a spline or an ellipse. Subsequently select a line and a
spline (ellipse), using the options and () respectively. Then specify the radius either by a
click or by inputting in the property window or parameters dialog box (the option ).
