Descrizione

The new element is drawn tangential to both attachment elements.
Note: Therefore, we say that such an element is constrained by both selected elements.

Depending on the selected type of the new element, some parameters of the element are maintained when attachment elements are edited.

The following types of new elements can be created between two existing elements: lines, curves, spirals, spiral-curve-spiral combinations, spiral-spiral combinations and the spiral-line-spiral combinations.

Options within the command

Line
Creates new line element between two existing curve elements. The new line is drawn tangential to both attachment elements. The tangency is maintained when attachment elements are edited.
The line can be added between the following element combinations:
  • Between two existing unconstrained circles.
  • Between two existing constrained circles as a part of combinations, such as a Curve with Spiral and a Curve-Spiral-Spiral combination.
  • Between an existing unconstrained and constrained circle.
Note: The way the line is drawn between the selected elements depends on their directions.
Curve
Creates a new curve element between two existing alignment elements. The new curve is drawn tangential to both attachment elements. The tangency and the curve radius are maintained when attachment elements are edited.

The position of points on (attachment) elements, between which new curve is created and the curve length are adjusted according to the editing of attachment elements.

The curve can be added between all element combinations except between the first selected element and the constrained spiral.

Note: The curve is defined by the type of attachment elements, specified curve radius and solution angle (< or >180°). The way the circle is drawn between the selected elements depends on the attachment elements direction.
Spiral
Creates new spiral element between two existing alignment elements. The new spiral is drawn tangential to both attachment elements. The tangency is maintained when attachment elements are edited.
Note: A free spiral is defined by the type and the direction of selected attachment elements. Since the spiral has only one geometric solution, the user cannot specify parameters, such as parameter A or the spiral length.
Spiral-Curve-Spiral
Creates new spiral-curve-spiral combination between two existing alignment elements. The new combination is drawn tangential to both attachment elements. The tangency, curve radius and both spiral lengths are maintained, when attachment elements are edited.

The position of points on (attachment) elements, between which new combination is created and the curve length are adjusted according to the editing of attachment elements.

Select attachment elements, specify curve radius and spiral lengths to add spiral-curve-spiral combination between selected alignment elements.

Spiral-Spiral
Creates new spiral-spiral combination between two existing curve elements with the same orientation and possibly different radii. The new combination is drawn tangential to both attachment elements. The tangency is maintained when attachment elements are edited.

Spiral parameters (length and parameter A) and the position of points on (attachment) elements, between which new combination is created, are calculated according to the specified A1/A2 (or L1/L2) ratio.

Note: The position of points on (attachment) elements, between which new combination is created and the curve length are adjusted according to the editing of attachment elements.
Spiral-Line-Spiral
Creates new spiral-line-spiral combination, with a specified spiral lengths, between two existing curve elements. The new combination is drawn tangential to both attachment elements.
Note: The position of points on (attachment) elements, between which new combination is created, and spiral parameters are adjusted according to the editing of attachment elements.
Specify first / second entity
Allows you to select the first and second alignment element, between which a new element is created.
Is curve solution angle
Toggles between Greaterthan180 and Lessthan180.
The figure below shows two possible solutions for a curve with an angle < 180° (left) and > 180° (right) added between an unconstrained line and an arc element.


spiral parameter A
Allows you to specify the A1/A2 ratio.
Spiral length
Allows you to specify the L1/L2 ratio.
Spiral in-length
Allows you to specify the spiral-in length.
Spiral out-length
Allows you to specify the spiral-out length.
The figure below shows the spiral-line-spiral combination, created between two unconstrained curves, where the user specifies the spiral-IN and spiral-OUT lengths.


Specify radius
Allows you to specify the radius of the new spiral and curve element.
