Contours for milling approach in the inside corners

General Usage Instructions

At the start, you can select two lines or a line and an arc. The main thing is to ensure that they are on the same plane and have a common point. 
Also, you can use Ctrl to select two segments of the polyline (liner or arched). During the selection of objects, you will have three options:
  • Diameter - input of the diameter of the mill
  • SubselectON/subselectOFF  - turn on sub-object selection mode (for polyline segments and solid edges), so as not to hold CTRL.
  • SwitchStyle - Quickly switch settings style using style number.
  • TUNE - call the setup dialog
You can select any cutter diameter. Default = 8mm or ½ inch.  
Note that by changing the diameter in this command, you will reconfigure it in the other contour processing commands (OutsideLoop and DadoLoop).
When entering the diameter, you can also select the Settings option to bring up the settings dialog.
The program will draw an arc with a diameter of a slightly larger cutter (0.01 mm) and place it in the corner so as to provide the finishing cutter a corner but leave a minimum extra hole.
The command can handle all internal corners of a closed polyline. Just program will ask you which side for milling.
It is also possible to make a notch at the 3D model. You can select a solid for cutting all inner corners or select a solid edge through CTRL which adjoin two flat surfaces to form the inner corner. On the cylindrical surface of the program is not working.

The program works on a cycle until you press the Esc

The program is designed to work with angles from 90°. For sharp corners, this method does not work because the resulting circuit has a very narrow section.
The program will automatically calculate the sharpest angle that a milling cutter can pass through a given gap. For example, if the cutter is 8mm and the gap is 0.01, then angles sharper than 87.1° will be ignored. If the gap is not specified, a limitation > 90° - 0.5° (angle tolerance) will be used.
It does not make sense doing calls in too obtuse angles because "notch" in the details may be hardly noticeable with less tolerance. The program automatically calculates the most obtuse angle for which it makes sense to make the cutter's approach (in which the arc enters part to a depth specified by the permissible tolerance). For example, for a cutter 8mm and a tolerance of 0.5mm, angles obtuse 122.1 ° will be ignored.
If the polyline segments are too short to make the arc between them, the program will ignore such segments, find the intersection point of the following segments and try to make a notch into this "imaginary" angle.
Watch for the command console - there are displayed all the messages of the program.
