Building an Element by Path |
Scroll |
To add to the model / cutout from the element along the path, call the appropriate command, set the construction parameters, check the correctness of the specified values with the help of a phantom and complete the operation.
Commands for building element along path
For creating an element over the trail, the commands Element over the trail 
and Cut over the trail 
are used.
Operation result
The result of the operation may be the union / cutting / intersection of the element along path with the existing solid, as well as the creation of a new solid. To select the desired option, use the group of buttons Result in the Main section of the Parameter Panel.
Options Merging and New solid allow you to add material to the model, and options Subtraction and Intersection – remove material from the model.

Section
Select a section to draw an element along a path. To do this, specify a sketch (sketch area), a planar curve, an edge of a planar face, or a planar face.
If the operation result is cutting or intersection (see above), then to build an element by path you can specify not only a section but also a solid, which will be used as a cutting tool.

Further editing of the operation Element by path may result in the objects selected as sections being replaced with other objects. In this case, the geometry of the model based on this operation may lose its link with its reference objects. To prevent this from happening, it is necessary to establish a correspondence between the initial result of the operation and the result obtained after replacing the section objects. For this, the Create with matching |
button is used in the Path
Specify the path of the section. The trajectory may be a 3D curve, a sketch line, an edge, or a chain of such objects in any combination.

Section Movement
Select the type of movement of the section along the path. The section can be moved while maintaining the angle of inclination between the section plane and the path, parallel to itself or orthogonal to the path. More details on selecting the type of section movement...
Changing cross-section shape
If the section is a sketch containing a closed contour, it is possible to construct an element whose section shape changes as the section moves along the trajectory. This change is determined by the values of dimension variables set in the sketch and/or by the parametric links of sketch elements with model objects.
To set the section change parameters, in the Changing the cross-section shape section, perform the following actions:
•Set the toggle switch Changing shape to position I (enabled),
•Set the parameters for section modification, for example, specify the functions for changing variable dimensions within the limits of the trajectory or the required values of the variables at selected points along the trajectory.

Checking form of section in trajectory points
When constructing an element with a changing section shape, section diagnostics are available at different points along the path.
To see the sizes and shapes of the cross section at the required points, in the Cross-section check section, perform the following actions:
•Set the toggle switch Display sections to position I (enabled).
•choose the section placement option using the toggle Row of sections/Section run,
•Specify the position of intermediate sections according to the selected option — the number of sections arranged along the trajectory at equal distances from each other, or the distance to the point on the trajectory where the section needs to be placed.

Section Cross-section check is present on the Parameter Panel, if the toggle switch Changing shape in section Changing the cross-section shape is set to position I (enabled). |
Creating a thin-walled element
When constructing an element with an unchanging cross-sectional shape, it is possible to create both solid and thin-walled elements.
If you want to form a thin-walled element, set its parameters in the Thin-walled element section:
•Set the toggle switch Thin-walled element to position I (enabled),
•determine the direction of building a thin wall and its thickness.

If the toggle switch Changing shape in section Changing the cross-section shape is set to position I (enabled), then section Thin-Walled Element is absent. |
Advanced Options of the element along the path
When building an element with a constant cross-section shape, changing the build optimization option is available. This can change the appearance of the resulting element if the trajectory of the section movement has a complex shape (for example, a spiral with a variable pitch). In the case of a simple path, all optimization options give the same result.
To change the optimization option, expand the Additional Parameters section and select the desired option from the Optimization Version list.
|
If the toggle switch Changing shape in the section Changing the cross-section shape is set to position I (enabled), then the section Additional Parameters is absent. |
Operation Application Area
The operation application area is a set of objects which should be transformed as a result of the operation. Specifying the area is required if the model contains several solids or components.
The controls for the operation application area are contained in the Application area section. This section is present on the Parameter Panel for any result of the operation, except for the creation of a new solid.
The operation application area can include solids 
, components 
, or components and solids 
. To select the desired option use a group of buttons Groups of objects.
The operation can extend to all objects of a selected group or to some of them. To select objects, the intersection with which will be taken into account when building, use a group of buttons Objects.

Trajectory element properties
You can specify the name of the element along the path and its surface display properties using the controls located in the Properties section on Parameter Panel (if needed).
Management of the color and optical properties of objects...
Completing the operation
To finish building an element along a path, click Create Object 
.
If the operation results in a solid consisting of multiple parts, then after completing the operation, the program starts the process of modifying this set of parts. Select the parts that should be left. Details...
After performing the specified actions in the graphics area, a new solid will appear, glued or cut out the element (depending on the selected result of the operation). In the Design Tree, a build element by path / cut operation will be displayed with one of the following icons:
glued element/new solid,
deleted element.
To complete operation of the command, click Finish 
.
•Wall thickness can be set using defining points.
•To set the linear parameters, you can use the commands of the geometrical calculator.
•You can assign tolerances to the values of the operation parameters expressed in linear values. To do this, use the Tolerance command located in the menu field of the parameter to be set.
