SDNF-Interface

The SDNF interface (Steel Detailing Neutral Format) serves for the exchange of CAD-data between programs being able to interpret this format. A static analysis system can of course also be transferred via the shape position.

File Format: ASCII text file with the extension *.sdf

Data Export

ProStructures can export CAD-system data for standard shapes, plates, and cuts, including polycuts, holes and slotted holes. The plane cuts are exported as polycuts.

Data Import

ProStructures can import CAD-system data for standard shapes, plates, and cuts, including polycuts, holes and slotted holes.

In addition, the static analysis system for standard shapes can be written. Depending on the settings on the General Settings page, it has tried to determine intermediate gussets for connections and eccentricities.

Setting	Description
Input Fields	Here, you enter the variable header area data of the SDNF-file.
Units	Here, you can choose the units for the output of length and coordinate values. In combination with a suitable exchange list it is thus possible to create a file with imperial units from a metric drawing file or vice versa.

Degree of Implementation

The implementation corresponds to standard SDNF-3.0; the following elements are supported in exchange:

Section	Description
Packet 00	Head Data (Title Packet)
Packet 10	Straight Standard Shapes (Linear Member Packet)
Packet 20	Polygonal Plates (Plate Element Packet)
Packet 22	Drill Holes (Hole Element Packet)
Packet 60	Bent Shapes (Arc Member Packet)
