CAD drafting Fillet 6 Command line: MFILLET

This command is used to create fillets in the intersection points of objects, with automatic dimensioning ability. The command can create fillets individually.

The Fillet command can be used for quick trimming or lengthening of selected objects. To do it, press SHIFT button when you select objects: a current value of fillet radius is temporarily changed to 0 and objects are lengthened or trimmed to intersection point.

CAD software Fillet 7

It is possible to make a fillet between parallel segments. A current value of fillet radius is temporarily changed to a value, which equals to half distance between parallel segments. The dialog box opens after the command is launched:

Parameters:

CAD drafting Fillet 9

This button switches on the lines cutting mode.

CAD software Fillet 10

This button switches to insert circle instead of fillet.

When performing an operation in this mode, the modes of dimensioning and complete or partial trimming of mating lines are ignored.

CAD drafting Fillet 12

Button to enable fillet insertion mode as a mate.

Radius

Radius of fillet.

CAD software Fillet 13

This button temporarily closes the dialog box to allow measuring of the fillet radius on the drawing. The Value picker dialog appears to perform measurements.

CAD drawing Fillet 14

This button fully cuts lines before their intersection.

CAD drafting Fillet 15

This button switches on the mode for cutting of lines before their intersection.

CAD software Fillet 16

This button switches on the mode without lines cutting.

CAD drawing Fillet 17

This button switches on the additional dimensioning mode.

The button becomes available when the CAD drafting Fillet 18 Measure fillet button is enabled.

CAD software Fillet 19

CAD drawing Fillet 20

This button switches the automatic dimensioning mode on/off.

CAD drafting Fillet 21

This button temporarily closes the dialog box to allow copying of properties from other fillet. The command does not work on fillets created with the participation of a polyline, since when setting up a fillet, all the components are collected into one polyline.

Show at start

A box that, when unchecked, stops displaying the dialog box for all subsequent command calls, i.e. allows you to reconfigure the command to work in non-dialog mode. To open the dialog box again, select the Properties option in the command line or context menu. This mode of operation is convenient when you often need to use the command without changing its parameters.

Abort command by Esc

When the box is checked, pressing ESC interrupts the command. When the box is unchecked, pressing ESC displays the Fillet dialog box.

Double-click or right-click in the fields to enter values will open the context menu with the list of the recently entered values:

CAD software Fillet 22

Options in the context menu and in the command line are available during the process of fillet creation:

CAD drawing Fillet 23

Command options:

Properties

The Fillet dialog box opens to change the chamfer parameters.

neW

Finishes the creation of one group of fillets and starts another. The command is applied when you need to create some fillets with one radius on one object and with the same radius on another object:

CAD drafting Fillet 24

Chamfer

Switches to the mode for creating chamfers. The Chamfer dialog box opens to specify the parameters of the fillet.

polyLine

Constructs fillets for all polyline vertices that are intersection points of two straight-line segments. The operation ignores clipping and dimensioning modes.

CAD software Fillet 25CAD drawing Fillet 26

To create a fillet:

       

1.      Select the first object.

2.      Move the cursor over the second object. Fillet options will be presented.

3.      If there are no fillet options, select the Properties option from the context menu or the command line and adjust the radius.

4.      Select the second object.

5.      Select the fillet from the presented options.

 

Features of the command work

The command works in 3D. To perform the command, the source entities should be located in the same plane.

If you press and hold SHIFT when selecting the second object, then a corner will be formed (closing in the intersection point and cutting off).

CAD drafting Fillet 27

For pairs of objects LINE-ARC, ARC-LINE and ARC-ARC, two types of fillet are available: outside and inside ones.

Outside                                                          Inside

CAD software Fillet 28 CAD drawing Fillet 29

A fillet that combines inside and outside tangency is additionally available for ARC-ARC pair.

CAD drafting Fillet 30

NOTE:               Availability of different types of fillet depends on the fillet radius. Outside and combined fillts require larger radiuses than for inside fillets.

Selecting two parallel lines will create a fillet with a radius equal to half the distance between them (regardless of the specified Length). The sides will automatically align to the longest line.

CAD software Fillet 31

Fillet of parallel lines also works for segments of the same polyline.

A fillet side depends on the mouse cursor position when the second object is selected

CAD drafting Fillet 33

When making an insertion of a fillet between neighboring polyline segments, a polyline retains its integrity.

CAD software Fillet 34 CAD drawing Fillet 35

If when using the command, a fillet is created for two polylines, then as a result it will be a single polyline object.

CAD drafting Fillet 36 CAD software Fillet 37

If segments of one polyline separated by other segments are selected, then all these intermediate segments are deleted.

CAD drawing Fillet 38

When making a fillet while specifying a second object, a point will be taken at the location of the object and a fillet will be constructed based on this point. Examples of fillets with the same parameters but different specified points:

Fillet Command (Non-dialog Mode)

CAD drawing Fillet 41 Command line: F, FILLET

Creates a fillet using the command line.

Command options:

?

Opens additional options for selecting objects.

Undo

Cancels a previous action in the command.

POlyline

Creates fillets for all polyline vertices which are the intersection points of two straight line segments. When the Trim option is enabled, fillet lines become new segments of polylines.

RaDius

Sets the fillet radius. When set to zero, objects are lengthened or cut to intersect.

Trim

Controls objects cut to fillet lines.

Trim -selected objects are removed to the endpoints of the fillet lines. If the objects do not intersect with the fillet line, they are lengthened or clipped to the endpoints of the fillet line.

No_Trim – selected objects are not cut.

Multiple

Adds a fillet to multiple sets of objects.

Command prompts:

Soecify first object or [?/Undo/POlyline/RaDius/Trim/Multiple]:

Select the first fillet object or the required option to set parameters.

Specify second object or Shift-select to apply corner or [?/RaDius]:

Select the second fillet object or use Shift key to form an angle in the intersection point. To change parameters, select the required option.
