5.21 Miscellaneous
5.21.1. Terminology
Nesting
Nesting is divided in the following way:
Element is the atom of a nesting. Element is the smallest part that can be edited. There are four different kinds of elements: lines,
arcs, circles and points.
Profile is a combination of one or more elements, which are connected to each other. At the starting point of a profile the sheet is
pierced and cutting starts. At the end point of a profile the torch is raised up and cutting stops.
Shape contains one or more profiles. Shape is a logical part, which has a boundary and possibly has some holes.
Nesting contains all the shapes, but can also be empty.
Transferline
Transferline is a path that the torch follows when it is not cutting.
5.21.2. Problems?
We have listed here some problems, which occur time to time, and solutions to them.
1. When starting ProMotion® Nest displays the following message “Registration error! Please, contact your dealer. Running in
demo mode.” and starts in the demo mode.
OFFICE PC:
ProMotion® Nest requires an activation file (license.txt) and a dongle to work. Please check the following things:
• The dongle is plugged into the PC’s USB or LPT port.
• You have installed drivers for the dongle.
• There is a license file (license.txt) in the ProMotion® Nest folder.
If all of the above are ok, then there may be something wrong with your license file. Please contact your dealer.
ICNC CONTROLLER:
Try to close ProMotion® Nest and then start it again. If that didn’t help, please contact your dealer.
5.21.3. DXF
Overview
DXF format is supported by most present day CAD softwares. DXF files can be either ASCII or binary formats. Because ASCII DXF files
are more common than the binary format, the term DXF file is used to refer to ASCII DXF files.
Requirements and Recommendations
DXF files are an interface between CADs and nesting software, like ProMotion® Nest. There are certain recommendations and require-
ments when creating and converting DXF to ProMotion® Nest, which should be noticed:
• It is useful to put geometries on their own separate layer and name that layer so that it is easily recognized (e.g. PROFILES).
ProMotion® Nest detects different layers and allows the user to choose which layers to load.
• If there are multiple parts, it is a good idea to put each of them on their own separate layer (e.g. PART1, PART2, etc.).
• Line and point markings must be placed on their own layers. Use POINT or CIRCLE entities for point marking.
• Draw the parts in 1:1 ratio. Do not scale them. ProMotion® Nest reads the coordinates as they are in a DXF file.
• Try to avoid open gaps between different elements. Use POLYLINE or other objects that draw a continuous line.
• All marking objects (point marking, line marking or text objects) must be inside parts. Outside objects are ignored.
• Supported objects are LINE, ARC, SPLINE, CIRCLE, POINT, POLYLINE, VERTEX, ELLIPSE, TEXT, MTEXT and SEQEND.
