This function is used to offset line geometry, and the offset result can be previewed. For a 2D line, it can only be offset on the plane where it is located. For a 3D line and straight line, the user is allowed to define the offset direction and/or LCS to offset. The dialog box is illustrated in Figure 5.1.38.

·          SELECT LINE

Click this button to display the Select Line dialog box for the user to select a line.

·          IN ORIGINAL PART

Put the created offset line in the original part. If this option is not toggled on, the created offset line will be put in the current part.

·          DELETE ORIGINAL LINE

Delete the original line when creating the offset line. If this option is not toggled on, the original line will not be deleted.

·          LCS

Define a local coordinate system and the offset operation will be executed on the UV-Plane. The default LCS is the global coordinate system. The user can select an existing C.S. from the drop-down menu, or click the Define button to create the LCS. If this option is not toggled on, the program will prompt the user to define the offset direction. Click the left mouse button to select a point on the offset line, move the mouse cursor up and down to define offset direction. Click the middle mouse button to confirm and the right button to exit.

·          DISTANCE

Define the offset distance.
