Building a Lofted Element |
Scroll |
To add lofted element to the model (cutting out from the model), call the appropriate command, set the construction parameters, check the correctness of the given values using a phantom and complete the operation.
Commands for building a lofted element
For constructing an element by sections, the commands Lofted Element 
and Cut by Sections 
are used.
Operation result
The result of the operation may be the union / cutting / intersection of the element with the existing solid, as well as the creation of a new solid. To select the desired option, use the group of buttons Result on the Parameter Panel.
Options Merging and New solid allow you to add material to the model, and Subtraction and Intersection options – remove material from the model.

Sections
Set the lofted element sections. To do this, specify objects-sections — sketches (sketch areas), 3D curves, faces — in the Design Tree or in the graphic area. All sections must be flat.

Further editing of the operation Lofted Element may replace the objects selected as sections with other objects. In this case, the geometry of the model based on this operation may lose the link with its reference objects. To prevent this from happening, it is necessary to establish conformity between the initial result of the operation and the one obtained after replacing the section objects. This is done using the Create with matching |
button in the Guide Line
If necessary, you can set the guiding line of the element by sections. A sketch, edge, or 3D curve can be used as the guide line.
To select a guiding line, click in the Guiding Line field, then specify the required object in the Design Tree or in the graphics area.

Ways to build an element at the extreme sections
When performing an operation, various ways of constructing an element at the extreme (first and last) sections are possible.
To select the method, use the Initial section and Final section groups of buttons.

Section Connection Path
The path of the sections connection can be closed or open-ended. To select the desired option, use the option Close Path.
This button is available when the following conditions are met:
•more than two sections are specified for building the element,
•The guide line is not used.
The element of the sections is formed by connecting the specified sections. If necessary, the connected section points can be specified manually. To do this, use the elements located in the section Connection.
To specify the points to be connected, click Add chain 
. The process of creating a chain of connected points will start. Set the points on each section.

Guide curves
The shape of the lofted elements can be changed by setting the guide curves. The existing objects in the model are used as guide curves: 3D curves, contours, sketches, edges. The number of guide curves is not limited.
To select existing objects as guide curves, in the section Guide curves click in the Curves box. Select the desired objects in the Design Tree or in the graphics area.

Creating a thin-walled element
Creating a thin-walled element is possible if all sections contain outlines. When using points in extreme sections it is possible to build only a solid element.
The parameters of a thin-walled element are specified in the section Thin-walled element:
•set the Thin-walled element toggle switch in position I (enabled),
•set the direction of building a thin wall and its thickness.

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.

Element properties by sections
If necessary, you can set the element name by sections and the properties of its surface display using the controls located in the section Properties.

Completing the operation
To finish building the lofted element, click to create the object 
.
If the construction results in a solid consisting of multiple parts, then after completing the operation, the program starts the process of modifying set of parts. Leave those parts you need.
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, the section operation / cutting operation icon is displayed:
attached element/new solid,
cut element.
To complete operation of the command, click Finish 
.
