Creating a Patch from Points

You can create a patch projected on a plane or fitted to a support by clicking two, three, or four points on an existing geometry or in the work area. The patch can also be created without any projection of points.

Create a Patch from Two or Three Points on a Plane

Before you begin: Create a 3D shape.
  1. Click 2-Point Patch or 3-Point Patch .
  2. Select Reference Support: Robot Plane.
  3. Select Projection Type: Planar Direction.
  4. Click to position the starting point.
    • Points selected in the work area directly lie on the specified plane.
    • Points selected on an existing geometry are projected onto the plane.
  5. To create a 3-point patch, do the following:
    1. Move the cursor to a different position.
    2. Click again.
  6. Move the cursor to form the patch.
  7. Complete the patch creation by doing one of the following:
    • Click again to define the opposite corner of the patch.
    • Right-click and select Edit Dimensions, enter the required values, and click OK.
  8. Click OK.

Create a Patch from Four Points on an Automatically Created Plane

You can create a planar patch from four points that is fitted to a plane, which is automatically generated from the first three selected positions.

Before you begin: Open an existing 3D shape containing a surface.
  1. From the Surface section of the action bar, click Unified Patch .
  2. Click 4-Point Patch .
    Auto Plane is selected by default in the Reference Support frame.
  3. Select three points on the surface or any existing geometry.
  4. Select the fourth point either in the work area or also on an existing geometry.
    The point is projected in the plane that is defined by the first three points.
  5. Click OK.
    The patch is created on this plane.

Create a Patch from Four Points Without a Reference Support

You can create a planar or nonplanar patch from four points that is not fitted a support.

Before you begin: Open an existing 3D shape or an existing Physical Product containing STL data and a 3D Shape.
  1. From the Surface section of the action bar, click Unified Patch .
  2. Click 4-Point Patch .
  3. Clear the Auto Plane and Reference Support check buttons.
    The options in the Projection Type frame are disabled.
  4. Select four points in the work area, on any existing geometry, or on STL data.

    When selecting a point in the work area, the position is computed by means of the Robot plane.

    All positions are kept as the points are not projected.
  5. Click OK.
    A patch of any shape is created.
