Sweep: Delta/Reference

Access: Open this function from one of the following locations:

Create a face by sweeping a curve, edge, contour or sketch in a specified direction.

Sweep the selected contour(s) / curve(s) on one or both sides, either by Delta (by a given value and direction) or by Reference (to a reference face, plane or point).

Demo: Press the button below to view a short movie demonstrating the function:

Practice: Press the button below to open Cimatron with a practice ELT file similar to that used to create the movie (if the relevant feature already exists in the ELT file, you can either edit it or delete it and create a new feature).



 

Required Step 1

Pick contour(s) / curve(s) and then <exit><exit>(middle mouse button).

Required Step 2

Set the sweep parameters and the direction. The following parameters are displayed:

One Side:

Both Sides:

The parameters displayed here are very similar to those displayed in the New > Extrude function. As such, references link to the New > Extrude function for further explanation.

The default direction is normal to the 2D contour or sketch plane. You can flip the direction by clicking the displayed arrow head or body, or you can click on the arrow origin to set another direction.

Delta/Reference

This is a dropdown list of the available sweep options - see Sweep: Options and Results.

One Side

This is a toggle option: One Side / Both Sides:

One Side

Sweep on one side of the contour.
Example:Example:

Both Sides

Sweep on both sides of the contour.
Example:Example:

In the Delta/Reference option, additional parameters are displayed. These parameter settings for each sweep side are displayed under their respective Primary Side and Secondary Side headings (for more information on these headings, see the New > Extrude: Additional Delta/Reference Notes and the New > Extrude: Labeling Rules). This option is useful in Die tools, where, in many cases, it is necessary to create the punch (for example, to a reference) and also to define a delta to the other side.

By Delta

This is a toggle option By Delta / By Reference.

By Delta

Sweep by a delta value. This option displays the Delta parameter; set this parameter to define the sweep distance.
Example:Example:

By Reference

Sweep to a reference entity (datum plane, face, object, curve(s), edge(s) or sketch(es)). This option displays the Delta from Reference parameter; set this parameter to define a delta distance from the reference face/plane.
Example:Example:

Pick the reference face/plane.

The contour is swept to the reference entity.

Delta from Ref. = 0

Delta from Ref. = <positive value>

Delta from Ref. = <negative value>

Note: Picking a reference point creates a plane going through the picked point and normal to the sweep direction.

The planar or non-planar attributes of the reference geometry determines the options that are displayed.
If the reference geometry is a planar face, the toggle option As Plane / As Object is displayed.
If the reference geometry is a non-planar face, the toggle option Face Extend / Object is displayed.

See the New > Extrude: Planar / Non-Planar Reference Face Options.

Notes on Default Sweep Direction:Notes on Default Sweep Direction:

  • For 3D curves, the default sweep direction is the shortest edge of the curve's bounding box (the box coordinates are according to active UCS). The bounding box is only calculated the first time you are in the function. The default direction is not changed upon updating.

  • For 2D curves, the default sweep direction will be normal to curve plane. This direction may change after updating.

Optional Step 1

Add a draft angle to the sweep. The parameters here are identical to those in New > Extrude: Defining a Draft Angle.
