Alternately, one can just use BlockSCAD for this directly:
First, create some variables:
and fill in some values:
Then create the first circle (after adjusting the values):
and use a translate command to position the second:
Then use a Hull() command to connect things:

The code may then be copied:
(note that this code has been modified as described below)
//!OpenSCAD
Left_Diameter = 30;
Right_Diameter = 20;
Distance_of_Centers = 40;
$fn = 360;
projection()
{
hull(){
cylinder(r1=(Left_Diameter / 2), r2=(Left_Diameter / 2), h=1, center=false);
translate([Distance_of_Centers, 0, 0]){
cylinder(r1=(Right_Diameter / 2), r2=(Right_Diameter / 2), h=1, center=false);
}
}
}
and pasted into OpenSCAD:
Adding a variable to improve the quality of the curves/arcs gives us a chance to show the Customizer:
which allows adjusting the values:
Since OpenSCAD is a 3D program, the design may be exported as an STL, or an additional command may be added to flatten it:
which allows exporting as a DXF:
tangent_circles.dxf (10.9 KB)
which may then be imported into Carbide Create:
