Importing Axi-symmetric mandrel data from a DXF file.

On the Cadfil Utilities menu there is an Imported DXF option. This reads a DXF file created in a CAD program and creates a mandrel file. For this to work the DXF file must be prepared in a certain way as described below.

The Mandrel data is defined by a 2D profile in the X,Y plane using lines and circular arcs

The axis of the mandrel should be the World X axis

The Lines and arcs for the mandrel must be joined to form a polyline or lwpolyline.

This polyline must be on a layer called MAN

The layer called MAN should contain only one polyline but can contain other data

The Envelope data (optional) must be prepared in the same way as the mandrel contour

The envelope polyline must be on a layer called ENV.

In the CadfilXXX\Data folder there is a sample DXF file called TESTMAN.DXF.

Cadfil has been tested on AutoCAD R12, R13, R14 & 2000 DXF files.
