Block - this is the name of the boundary to which the menu refers. Copy - copies the selected segments to the clipboard

Paste - pastes the entities on the clipboard into the boundary. Copy and paste works between model, boundary and pattern entities.

Only closed segments are pasted into boundaries.

Only wireframe geometry can be pasted from models into boundaries or patterns.

You can copy and paste data within PowerMILL or from one PowerMILL session to another.

Activate - makes the boundary the active boundary.

Activate Workplane - activates the workplane used to create this boundary.

Settings (see "Boundary - Settings" on page 136) - displays the parameters used to define the boundary.

Recreate Block - recreates the block used to create this boundary. Select Surfaces - selects the surfaces used to create this boundary. This option only displays a result if you had to select specific surfaces to create the boundary.

Draw - determines whether the boundary is displayed on the screen or not. So it toggles between and .

Add to Folder - adds the selected entity to the active folder. If the option is greyed out check that you have an active folder.

You can only add a Toolpath entity to a Toolpaths folder. You cannot add a Toolpath entity to a NC Program folder.

For more information see Folders (on page 260).

Rename - allows you to rename the entity to give it a more meaningful name.

Select All - selects all segments of the boundary (they turn yellow). Deselect - deselects any selected boundary segments (they turn white). Save - saves the modified boundary. The Save Boundary dialog is displayed. This is a standard windows save dialog.

Edit (see "Edit - Boundary" on page 137) - displays the editing options. Insert (see "Boundary - Insert" on page 145) - inserts entities into the boundary.

Calculate - calculates a "Batch" boundary created by selecting one of the Create Boundary options in the Boundary context menu and then clicking on Accept rather than Apply. A "Batch" boundary is preceded with a to show that it needs to be calculated before it can be used. Undo Last Edit - reverts the boundary to what it was before the edit. Redo Last Undone Edit - reinstates the edit you have just undone. Clear History Buffers - empties the undo buffer, so that you can no longer undo an edit.

Remove From Folder - removes the feature set from the current folder. It converts this:

to this:

For more information see Folders (on page 260). Delete Boundary - deletes the boundary.

Boundary - Settings

Settings - displays the parameters used to define the boundary. In the case of a shallow boundary that has been used to create a toolpath the following dialog box is displayed:

The fields that can be edited are white those that cannot be edited are grey. The editable fields depend on whether the boundary has been used in a toolpath. If it has then the Name is the only editable field. If the boundary hasn't yet been used to create a toolpath then all the fields can be edited.

Edit - Boundary

Edit - displays the editing options.

Transform (see "Transform Boundary" on page 138) - allows you to move, rotate, scale or mirror a boundary.

Points (see "Boundary - Edit - Points" on page 139) - defines how to move, delete or add points to the boundary. Initially select the required Mode, then select the required points and finally click on Apply.

Arc Fit Selected (on page 139) - arc fits selected segments. This is used to smooth boundaries.

Spline Selected (on page 140) - this turns the sketched boundary into a spline.

Polygonise Selected (on page 141) - this converts a curved boundary to a series of straight lines.

Flatten - The boundary is projected (or flattened) onto the XY Plane at Z = 0. In this case the boundary need not be entirely contained within the part.

Offset 3D (on page 141) - offsets a 3D boundary by a specified distance. A positive value offsets the boundary outwards, a negative valued offsets the boundary inwards.

Offset 2D (Round Corners) (see "Offset 2D (Round)" on page 142) - offsets a 2D boundary by a specified distance. A positive value offsets the boundary outwards, a negative valued offsets the boundary inwards. The offset has rounded corners.

Offset 2D (Sharp Corners) (on page 143) - this is very similar to Offset 2D (Round Corners) except that the offset pattern has sharp corners.

Select Duplicates - selects all duplicate segments of the boundary. This can be used very effectively in combination with Delete Selected to delete all the duplicate boundary segments.

Select Area (on page 144) - allows you to select a boundary segment by area. This only works on closed segments.

Make Invalid - this is similar to Invalidate All from the Toolpath or Boundary context menu, except that this option only applies to this boundary rather than all boundaries. For more information see Updating Toolpaths when a Model Changes (on page 75).

Copy Boundary - This creates a copy of the whole boundary. This new boundary has the same name as the original with _1 added to it. This new boundary can then be edited using the Parameters menu option.

Copy Boundary (Selected only) - creates a copy of the selected segments of the boundary. This new boundary has the same name as the original with _1 added to it. This new boundary can then be edited using the Parameters menu option.

Delete Selected Components - deletes all the selected segments of the boundary.

Transform Boundary

Transform - allows you to move, rotate, scale or mirror a boundary. It displays the following dialog:

This is very similar to the Transform Model (see "Transform Model dialog" on page 227) dialog, except for the the addition of Transform Copy option.

Transform Copy - when selected, the boundary specified above is copied when transformed and is given the name of the original boundary with the addition of _1. When deselected, the current boundary is replaced by the new transformed boundary which has the same name as the original toolpath.

Boundary - Edit - Points

Points… - displays the Boundary Editor dialog. This defines how to move, delete or add points to the boundary. Initially select the required Mode, then select the required points and finally click on Apply.

Selected points are marked in red. To de-select points, press the Ctrl key and re-select the point(s).

However, if you want to delete a boundary segment you don't have to raise this dialog. All you need to do is select the segment and then click on the Del key. For more information see Boundary Editor Dialog (on page 1005).

Arc Fit Selected

Arc Fit Selected - arc fits selected segments. This is used to smooth boundaries.

You are then asked for an arc fitting tolerance.

The boundary is then modified to the following:

Spline Selected

Spline Selected - this turns the sketched boundary into a spline.

You are then asked for an arc fitting tolerance.

Polygonise Selected

Polygonise Selected - this converts a curved boundary to a series of straight lines.

You are then asked for an arc fitting tolerance.

The boundary is then modified to the following:

Offset 3D

Offset 3D - offsets a 3D boundary by a specified distance. A positive value offsets the boundary outwards, a negative valued offsets the boundary inwards.

You are then asked for an offset distance.

The boundary is then modified to the following:

Offset 2D (Round)

Offset 2D - offsets a 2D boundary by a specified distance. A positive value offsets the boundary outwards, a negative valued offsets the boundary inwards.

Selecting the Edit - Offset 2D (Round Corners) will give you:

Offset 2D (Sharp Corners)

Offset 2D (Sharp Corners)- This is very similar to Offset 2D (Round Corners) (see "Offset 2D (Round)" on page 142) except that the offset pattern has sharp corners.

Selecting the Edit - Offset 2D (Sharp Corners) will give you:

Select Area

Select Area - allows you to select a boundary segment by area. This only works on closed segments.

There are two options Greater Than and Less Than. In either case the Ratio of Tool Area dialog is displayed.

Enter the required ratio and then click . A value of 1.0 matches areas equal to the area of the tool radius circle.

Greater Than - selects boundary segments whose area is greater than, or equal to, the amount you specify in the dialog.

Less Than - selects boundary segments whose area is less than the amount you specify in the dialog.

Boundary - Insert

Insert - inserts entities into the boundary.

Boundary - inserts another boundary into this one. The Entity Name dialog is displayed.

Enter the name of the boundary that you want to insert and then click the button.

File - inserts a *.dgk or *.pic file into the boundary. The Open Boundary dialog is displayed. This is a standard Open dialog.

Model - defines the boundary from the selected surface edges and adds them to the boundary. If no specific surfaces are selected then it works on the whole model.

From this model geometry with one surface selected (using the left mouse button):

The following boundary is created:

Sketch - enables you to sketch a boundary. This displays the Boundary Sketcher dialog.

For more information see Boundary Sketcher Dialog (on page 1002). Curve Modelling - displays PowerMILL's curve modelling

functionality which allows you to inserts a curve into the current

boundary. For more information see Insert into Boundary (on page 1000). Wireframe Modelling - displays PowerMILL's wireframe modelling functionality which allows you to inserts wireframe into the current

boundary. For more information see Insert into Boundary (on page 1000). Active Toolpath - converts the currently active toolpath to a boundary and inserts it into the boundary. If this option is greyed out then you have no active toolpath.

Active Pattern - converts the currently active pattern to a boundary and inserts it into the boundary. If this option is greyed out then you have no active pattern.
