|Draft -> Circle|
|Wprowadzono w wersji|
The Circle tool creates a circle in the current work plane by entering two points, the center and the radius, or by picking tangents, or any combination of those. It uses the Draft Linestyle set on the Draft Tray.
How to use
- Press the button, or press then keys.
- Click a first point on the 3D view, or type a coordinate and press the button.
- Click a second point on the 3D view, or enter a radius value.
The circle can be edited by double clicking on the element in the tree view, or by pressing thebutton. Then you can move the center and radius points to a new position.
The circle can be turned into an arc after creation, by setting its first angle and last angle properties to different values.
- The primary use of the circle tool is by picking two points, the centre and a point on the circumference.
- By pressing , you can select a tangent instead of picking a point. You can therefore construct several types of circles by selecting one, two or three tangents.
- To enter coordinates manually, simply enter the numbers, then press between each X, Y and Z component. You can press the button when you have entered the desired values to insert the point.
- Press or click the checkbox to toggle continue mode. If continue mode is on, the Circle tool will restart after you finish the circle, allowing you to draw another one without pressing the tool button again.
- Press DATAMake Face ); if not, the circle will not make a face (DATAMake Face ). or click the checkbox to toggle filled mode. If filled mode is on, the circle will create a filled face (

A Circle object shares all properties from a Draft Arc, but some properties only make sense for the circle.
- DATAFirst Angle: specifies the starting angle of the circle; normally 0°.
- DATALast Angle: specifies the ending angle of the circle; normally 0°.
- DATARadius: specifies the radius of the circle.
- DATAMake Face: specifies if the Circle makes a face or not. If it is a face is created, otherwise only the circumference is considered part of the object. This property only works if the shape is a full circumference.
- For it to be a full circle DATAFirst Angle and DATALast Angle should have the same value; otherwise, a Draft Arc is displayed. The values 0° and 360° aren't considered the same, so if these two values are used, the circle will not form a face.
- VIEWPattern: specifies a Draft Pattern with which to fill the face of the circle. This property only works if DATAMake Face is , and if VIEWDisplay Mode is "Flat Lines".
- VIEWPattern Size: specifies the size of the Draft Pattern.

True, the circle will make a face, that is, it will appear filled.
