# There are rounded lines

### Rounding and chamfering

#### Round objects

With the Fillet tool (“Construction” tool palette) you can connect two object edges (lines, rectangle sides, circles, etc.) with one another with a tangential circular arc with any radius. All you have to do is draw a guideline from one edge to the other.

The Fillet tool can be used on lines, rectangles, polygons, polylines, circles, arcs and NURBS curves. It is not only possible to connect two objects of the same type with a tangential circular arc. It is Z. B. also possible to fillet a circle and a line.

##### Fillet circles

Eight tangential arcs can always be constructed on two circles. Which of these eight possible arcs is drawn depends on which point of the first circle to which point of the second circle you draw the guideline. The following figures show how you have to draw the connecting lines in order to reach the various fillets. The four other possible arcs are each mirror-inverted on the other side of the connecting line between the two circle centers.

Different tangential arcs can also be constructed on a circle and on a line. Here, too, the position of the start and end point of the guideline determines which arc is drawn.

##### Methods

As soon as you activate rounding, four symbols and a text field appear in the method line. How the objects or object edges that are connected with a tangential circular arc are influenced depends on which of the first three method symbols is active.

##### Do not cut stretches

If this method is active, the rounded objects are not affected.

##### Cut up stretches

With this method, the two object edges are cut and can be moved or deleted individually after being rounded.

##### Delete sections

If this method is activated, the processed object edges are cut and the protruding parts are deleted.

TIP: The second and third methods can be used on lines as well as on rectangles, polygons, and so on. But if you connect a line and a side of the rectangle, the line will be cut and the protruding part will be removed with the third method, but the rectangle remains unchanged.

Here you can determine the radius of the circular arc. If you do not enter anything, the largest possible radius will be drawn.

Chamfer objects

#### Chamfer objects

Activate the Chamfer tool (Tool palette “Construction”> Lower tool of rounding), two object edges (e.g. lines, rectangle sides, polygon sides, NURBS curves) can be connected with each other by a diagonal, a so-called “chamfer”.

With the "Chamfer" tool, you can connect two objects with one another with a chamfer or you can chamfer individual objects that have corners (e.g. rectangles, polygons). The chamfered edges can - depending on which method is activated - either be retained, cut or deleted. Follow these steps:

1. Choose the method you want.

2. In the "Chamfer Settings" dialog box (open via the fourth method symbol) or in the text fields in the method line, enter the distance between the chamfer and the corner points of the edges.

3. Click on the first edge and drag a guide line to the second edge. The chamfer is then drawn in the desired position.

##### Methods

As soon as you activate the Chamfer tool, four symbols and one or two text fields appear in the method line.

##### Do not cut stretches

If this method is active, the chamfered edges are not affected.

##### Cut up stretches

With this method, the two edges are cut and can be moved or deleted individually.

##### Delete sections

If this symbol is active in the method line, the processed edges are cut and the protruding parts deleted.

##### "Chamfer Settings" dialog box

If you click on the fourth method symbol, the “Chamfer Settings” dialog box appears. It appears automatically when you draw the first chamfer and have not yet entered any values. You have three options for defining the desired chamfer: via the distance to the corner point in both directions, via the distance to the corner point of the first segment and the angle of the chamfer, or via the length of the chamfer.

1 “Mode” - With these three options you determine how the chamfer is to be defined.

"First and second segment" - If you activate this option, you can determine the distance to the corner point of the edge the chamfer should have in both directions. Under First route, enter e.g. For example, if you enter "1 cm", the bevel is set 1 cm from the end point of the first section. If you enter the value "2 cm" under Second section, the chamfer on the second section will end 2 cm before its end point.

"First segment and angle" - If you activate this option, the chamfer is drawn using the distance from the end point of the first segment and an angle. Enter e.g. B. Enter “2 cm” under First distance and “45 °” under Angle, beveled as shown below.

"Chamfer length" - If this option is activated, a chamfer is drawn in the length entered.

2 "Values" - Enter the desired values ​​for the chamfer here.

##### First segment, second segment, angle or chamfer length

Which text fields are displayed here depends on which mode you have selected in the "Chamfer Settings" dialog box. Here you can enter the required values ​​for the length of the first and second segment, the angle or the chamfer length.

##### Connect the line and the side of the rectangle with a chamfer

The methods “Draw and cut chamfer” and “Draw and erase chamfer” can be used on lines as well as on rectangles, polygons, etc. However, if you connect a line and a side of the rectangle, this method cuts the line and - depending on the selected method - removes the protruding part, but the rectangle remains unchanged.

##### Chamfer on an object

The chamfer tool can also be used to chamfer individual objects that have corners. It is possible to provide a corner with a chamfer in a rectangle, a polygon or a polyline; With polylines, only corners can be chamfered. If you create a chamfer on one of these elements with the first or the second method, the object is not changed, just a line with the defined properties is drawn.

With the third method, the element that is to be chamfered is converted into a polyline, the corner point of which is cut off according to the entries in the "Chamfer Settings" dialog box.
