Selecting Guiding and Relimiting Elements

You can select guiding and relimiting elements in several ways.

This task shows you how to:

Specify Guiding Contours

You can specify guiding contours in several ways.

Either

In the Contour section right-click and select Contour detection in the bottom context menu and select the bottom element. The boundary of the selected face is proposed as guiding contour.
or select edges. In this case the Selecting Edges and Faces to Define Geometry appears to help you specify the guiding contour.
or select By Belt of Faces or By Boundary of Faces in the guiding element context menu. In this case the Selecting Edges and Faces to Define Geometry appears to help you specify the guiding contour.

You can restrict the guiding contour with Start and Stop relimiting elements.

Optional: Select the Normal View icon in the View action bar and a suitable face.
The screen view is then perpendicular to the selected face and makes it easier to define relimiting point locations on the guide when moving the pointer.
Once a guiding contour has been defined, right-click the relimiting element in the sensitive icon and select Add relimiting point.

Note: More than one relimiting elements are not supported and if you select one relimiting element after another then a warning message appears, Element cannot be selected. An element has already been selected as limit. No more element is added. Remove the selected Element if possible, OK
If associativity with the part is requested:
1. Create the points in the same product as the part,
2. Select the points.

If associativity with the part is not requested:

Select points on the fly anywhere on the guiding contour.
or select Relimitation point detection in the context menu. Select a guiding contour, its extremities are used as relimiting elements. Direct selection of a sketch does not automatically detect its relimitation points. To detect relimitation points, you must select geometric elements using the edge wizard.

Important:

Points created on the fly do not provide associativity with the part. Such points are only known via their XYZ coordinates. Since they are not part of the same Product as the part, cannot ensure that their location is kept for each and any transformation applied to the part.
Basic scenario where points are created on the fly on part1, then part1 is mounted on the machine once is supported. But an advanced scenario with several transformations (example, create the points on the fly on part1, mount part1, change part1 to part2, mount part2) is not supported. Create points on the fly only in a machining scenario where there is no move, nor change of the part.
If only one relimiting element is defined along an open guiding contour, the area to be machined is either between:
- Limit1 and the extremity of the guiding contour
- The extremity of the guiding contour and Limit2

Position the tool, In, On, Out with respect to the Stop and Start relimiting elements.

You can machine several discontinuous groups of guiding elements in all Profile Contouring modes (except By Flank Contouring).

Select the contours as explained above.
A Guide.x element is displayed for each selected continuous ordered contour.
- The side to mill is shown by the orange arrow.
- The order of in which the geometric elements are selected determines the order in which they is machined.
Optional: Click the arrow to inverse the side to mill.
Insert a linking macro to link two discontinuous portions of the same tool path. Otherwise, a straight line is generated.
Once the selection of the guides is validated (that is, when the dialog box is displayed again), use the context menu that appears either on a guide in the 3DEXPERIENCE platform or on a guide in the sensitive icon of the dialog box.
1. Select Remove Element or launch the Edge Selection action bar and pick an element again.
  If the guide is no longer continuous, another guide is created.
