Circle > Center and Radius

Access: Open this function from one of the following locations:

Select Wireframe > Create Curves > Circle from the menu bar.
Select Curves > Circle from the following Die Design Guides: Strip Design.

Create a Circle/Arc by picking its center point and defining its radius.

Demo: Press the button below to view a short movie demonstrating the function:	Practice: Press the button below to open Cimatron with a practice ELT file similar to that used to create the movie (if the relevant feature already exists in the ELT file, you can either edit it or delete it and create a new feature).

Required Step 1

Select the required parameters and pick the appropriate entities.

The following parameters are displayed for this Circle function.

Radius by Value

Dropdown list of options to decide how the radius is to be defined. The following options are available under Center and Radius.

Dropdown list optionsDropdown list options

Radius by Value

Define the radius by entering a value in the Radius parameter.
This is the default option. The interaction is as follows:

Pick the center point of the circle to be created.
Set the radius and the other parameters as required.

See the example interaction below.

Radius by Point

Define the radius by picking a point. The interaction is as follows:

Pick the center of the circle.
Pick a point which defines the radius of the circle.
Set the other parameters as required.

See the example interaction below.

Radius by Tangent to Curve

Define the radius by picking a curve which will be tangent to the circle. The tangent point defines the radius of the circle. The circle may be created on the extension of the picked curve. The interaction is as follows:

Pick the center of the circle.
Pick a curve which will be tangent to the circle. The tangent point defines the radius of the circle.
Set the other parameters as required.

See the example interaction below.

Depending on the option selected, the following parameters are displayedthe following parameters are displayed.

Radius

Set the radius of the circle.

Start

Set the start point of the circle.
ExampleExample

In the images below, the start point of the circle is at the base of the BLUE directional arrow (this arrow appears if the Angle < 360° and is only displayed here to show the start point location). The images below show multiple arcs.

Start = 0°	Start = 25°

Angle

Define the angle of the circle (360 deg) or arc. If the Angle < 360°, a directional arrow is displayed at the Start point of the arc. Flip the direction of the arc by picking the direction arrow.
ExampleExample

The images below show multiple circles/arcs.

Start = 0° Angle = 360°	Start = 0° Angle = 180°	Arc direction flipped

Multi Wires /
Single Wire

This toggle option defines numerous circles/arcs as a single wire or multiple wires.
ExampleExample

Single Wire

When numerous circles/arcs are created, they are defined as a single wire (the circles/arcs are regarded as one wire). This is illustrated below, where pointing to one of the circles highlights all the entities in the single wire.

Multi Wires

When numerous circles/arcs are created, they are defined as multiple wires (the circles/arcs are regarded as separate wires). This is illustrated below, where pointing to one of the circles highlights only the relevant entity.

The subsequent interaction depends on which sub-option is selected:

Radius by ValueRadius by Value
Define the radius by entering a value in the Radius parameter (this is the default option). The following interaction is required:
1. 1. Pick the center point of the circle to be created.
1. 1. Set the radius, and the other parameters as required.
1. 1. In the case of an Arc, define the Start Point and the Angle.
1. 1. If necessary, flip the direction of the arc by picking the direction arrow.
There is only one possible solution.
Radius by PointRadius by Point
Define the radius by picking a point. The following interaction is required:
1. 1. Pick the center of the circle.
1. 1. Pick a point which defines the radius of the circle.
The required circle/arc is displayed.

There is only one possible solution.
1. 1. Set the other parameters as required.
Note: If you change the defined plane in Optional Step 1, the radius will be recalculated according to the projection of the picked point on the new defined plane.
Radius by Tangent to CurveRadius by Tangent to Curve
Define the radius by picking a curve which will be tangent to the circle. The circle may be created on the extension of the picked curve. The following interaction is required:
1. 1. Pick the center of the circle.
1. 1. Pick a curve which will be tangent to the circle. The tangent point defines the radius of the circle.
The required circle/arc is displayed.

There is only one possible solution.
1. 1. Set the other parameters as required.
