Building a multiline |
Scroll |
To build a multiline, use the Multiline
command.
Step-by-step instructions
1.Specify the line parameters Multiline parameters (number, offset, line styles) using the elements of the Lines and limiters section on the Parameter Panel.
|
You can copy the line parameters of the previously constructed multiline using the Copy Propertiescommand. |
2.Select the method of passing the corner near the vertex of the baseline by clicking the required button in the Corner Passing group:
By slice,
By fillet,
By Variable Radius Fillet.
3.Select the type of the first multiline segment using the Segment type button group:
Straight-line,
Arched,
By object.
4.Build the first segment of the baseline of the multiline.
•For a straight segment, set the start and end points, and for the arc segment, also set a point on the arc. After specifying the first point of the segment, a phantom of the baseline appears in the graphics area.
You can specify the direction of the segment by specifying an existing object. For this purpose, straight line objects (segments, straight lines, axes) and curves (circles, ellipses, arcs, conical curves) are used.
To select an object, click Select Base Object
and specify it before defining the last point of the segment. The name of the object is displayed in the Object field.
|
You can also select an object by disabling bindings. To do this, select the object while holding the <Alt> key (temporarily disable all bindings), or disable bindings that interfere with the indication of the object. |
When specifying objects, the method for designing a segment is determined by the system automatically depending on which objects are specified. For example, if a straight-line object is specified during the construction of a segment, the segment may be parallel or perpendicular to it. This is determined by the direction of the cursor movement. In cases when several options for constructing objects are possible, the option that is closest to the object’s indication point is automatically selected.
When building the first multiline segment, the methods described for the first autoline segment are available:

•To include a previously created object (segment, arc, spline, etc.) in the baseline, specify it in the graphics area.
Construction of segment by object
|
During the construction of a straight-line or arc segment of a multiline, the Parameter Panel displays the parameter fields of the object: coordinates of the start and end points, length and angle (for a segment), radius or diameter (for an arc). These fields are used in the same way as when creating lines and arcs using special commands. For example, a segment can be constructed by specifying its starting point, length and slope angle, and when building an arc, instead of a point on the arc, you can specify its radius/diameter. |
|
You can use snaps and geometrical calculator. |
5.A phantom of a multiline is displayed in the graphics area.
After creating first segment, the system waits for the construction of the next segment of the same type. If necessary, change the type of the second multiline segment.
6.Build the second segment of the multiline. The starting vertex of the second segment is the ending vertex of the first segment. The remaining parameters are set similarly to the first segment. The order and methods of constructing the second and all subsequent segments are the same as when building an autoline segment:
Methods of building subsequent segments
Methods of building consecutive arcs
7.Similarly, build all required multiline segments.
8.Select the multiline construction option – closed or open. To do this, use the Close option. Multiline is closed by a straight segment.
|
A multiline consisting of one straight or spline segment cannot be closed. |
9.For open multiline, you can enable the formation of constraints, and set their parameters. For this, the Limiter 1 and Limiter 2 toggles in the section Lines and limiters are used.
10.If you want to edit the baseline of a multiline, switch to editing mode. In this mode, you can change the position of the vertices and how to bypass the angle in them, as well as add or delete vertices.
After making changes, you can continue multiline construction by returning to Creation mode.
11.To complete building the multiline, click Create object

12.To complete operation of the command, click Finish
