Split Faces: Split Faces > By Curve / Edge

Split one or more faces by a splitting curve or edge. There are two options:

• Single surface- The curve can be projected onto a single surface.
• Picking multiple faces - The curve can be projected onto multiple faces.

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).

Single Surface

Required Step 1

Pick the face(s) or object to be split.

The Faces / Object toggle option is displayed, enabling you to pick either face(s) or an object to be split. For this example the Faces toggle option is selected (see the split methods for additional information). To split a single face, pick the face to be split.

<exit><exit>(middle mouse button) when the face is selected.

Required Step 2

Pick the splitting curve or edge. This can also include sketches and composite curves.

Project the splitting curve onto the face to be split (using one of the projection toggle options) and set the displayed parameters:

Define the method that the splitting curve is projected onto the face to be split. This is a toggle option: Normal Projection / Direction Projection.

Normal Projection

The splitting curve is projected normal onto the face to be split, as shown below. When this option is selected, the following parameters are displayed: Accurate This is a toggle option which enables you to define the accuracy of the split operation. The toggle options are: Accurate / Loose (Tolerant): Accurate This option produces a more accurate split operation by enabling you to set a larger Max. Distance value (larger than 0.1 mm (0.0039 inches)). In this case, the split operation takes longer. See Max. Distance below. Loose (Tolerant) This option results in a quicker split operation as the Max. Distance value is limited to 0.1 mm (0.0039 inches) and the resulting geometry is tolerant (up to 0.1mm or to the Max. Distance of the edge from the face). See Max. Distance below.   Max. Distance This parameter controls how far the splitting curve can be from the faces to be split and still perform the operation. If the Loose (Tolerant) option is selected above, a maximum distance of 0.1 mm (0.0039 inches) should be used (for optimal performance and success rate). If a value greater than 0.1 mm is used, the split operation takes longer as the splitting curve or edge is first projected onto the face and then the face is split.

Direction Projection

Direction arrows are displayed enabling you to define the direction by which the splitting curve is projected onto the face to be split. When this option is selected, the following toggle option is displayed: One Side / Both Sides Split the face on one side or both sides of the splitting curve.

Click OKOK or ApplyApply in the Feature Guide to complete the function.

The face is now split into two faces, for example:

When completed, the Split will appear in the Feature Tree as follows:

Picking Multiple Faces

Required Step 1

1. To split multiple faces, pick the faces to be split (three faces in the example below) and <exit><exit>(middle mouse button).

Required Step 2

Pick the splitting curve or edge (in this example a spline).

The option Normal Projection is the default whereby a curve is projected onto a face in a normal direction. Toggle to Direction Projection to project a curve in a user-defined direction.

Click OKOK or ApplyApply in the Feature Guide to complete the function.

The faces are now split accordingly. The drawing below shows both Normal Projection (red) and Direction Projection along the Y-axis (green).

When completed, the Split feature will appear in the Feature Tree as follows:
