Creating Split Line Sketches
A molded part or casting usually requires two or more shapes to define the
part. To make a mold or a cast, you create the shape of your part and then
apply a split line to split the part into two or more pieces. You may also need
to apply a small draft angle to the faces of your part so that your part can be
easily removed from the mold.
Split lines can be as simple as a planar intersection with your part, or as com-
plex as a 3D polyline, or spline, along planar or curved faces.
You can also split parts using either
A selected planar face or a work plane
A sketch projected onto a selected set of faces
In this exercise, you create a split line to split a shelled part into two separate
parts.
Open the file sketch4.dwg in the desktop\tutorial folder.
NOTE Back up the tutorial drawing files so you still have the original files if you
make a mistake. See Backing up Tutorial Drawing Files on page 40.
The drawing file contains a simple shelled box. Two viewports have been
defined: the right side of the part, and an isometric view. Youll define a new
sketch plane in the right viewport and sketch a split line in the left viewport.
