Draws an arc tangent to two selected lines.
How to use
1. Click the Fillet arc icon or choose the Tools > Curves > Circle > Fillet arc: 2 lines command.
2. The program console prompts Tangent line #1.
3. Pick the first line to which the circle will be tangent. Keep the mouse button pressed and drag for positioning the arc end point along the tangent. Release the mouse button when you have reached the desired position.
4. The program console prompts Tangent line #2.
5. Pick the second line to which the circle will be tangent. Keep the mouse button down and drag interactively for defining the arc and positioning the other arc end point along the tangent. Release the mouse button when you have reached the desired position.
Default radius value of the arc is 1.
Options
Tangent line #1
To change the first line to which the arc is tangent.
Views / Modeling Tool panel. Switch the Replace check button on and pick another tangent line in the scene.
End point # 1
To modify XYZ coordinates of the arc end point on line 1.
Views. Choose the Edit mode. Click the point and drag it. Release the mouse button when you reach the desired position.
Modeling Tool panel. Type the new values in the XYZ data fields and confirm them by pressing Enter.
Tangent line #2
To change the second line to which the arc is tangent.
Views / Modeling Tool panel. Switch the Replace check button on and pick another tangent line in the scene.
End point # 2
To modify XYZ coordinates of the arc end point on line 2.
Views. Choose the Edit mode. Click the point and drag it. Release the mouse button when you reach the desired position.
Modeling Tool panel. Type the new values in the XYZ data fields and confirm them by pressing Enter.
Radius
To change the preferred radius.
Views. Choose the Edit mode. Click the Radius point hotSpot and drag it. Release the mouse button when you reach the desired radius.
Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter.
Arc type
To specify whether the circle must be weighted (exact) or non-weighted (approximated).
Modeling Tool panel. Switch the chosen radio button on. You can choose either Weighted or Non-weighted. If you choose the first option the number of control points is automatically defined. With the second option you can set the number of control points in the section below.
Note: in general, you could use Weighted if you do not plan to modify the original shape and Non-weighted if you want to edit it.
Points
To determine the number of control points of the circle in case you have chosen Non-weighted in the above section.
Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter (remember: the more the control points, the more approximated the circle).
Options
To specify various options.
Modeling Tool panel. To enable the available options, switch their check buttons on:
Invert arc. To invert the arc direction.
Fit tangents. The fillet arc will cut the tangents at the intersection points. Fillet arc and tangents will be joined to a single element. If you enable this option, you have two more possibilities:
Invert tangent #1. To invert the portion of tangent to be cut.
Invert tangent #2. To invert the portion of tangent to be cut.
The Modeling Tool panel also displays the sweep Angle of the arc. This is not directly modifiable.
