CIS/2 (CIMsteel Integration Standards) is a standard interchange format to facilitate data flow between applications which intervene in the analysis, design and fabrication process of steel structures.
CYPECAD, Metal 3D and the Integrated 3D structures of CYPECAD can export the introduced and designed structure in CIS/2 format, advised by the NIST (National Institute of Standards and Technology).
Graitec Advance Steel is one of the applications related with the modelling of 3D steel structures for which the correct import of the CIS/2 format generated by CYPECAD, Metal 3D and Integrated 3D structures of CYPECAD has been tested.
Export in CIS/2 format from Metal 3D, CYPECAD and Integrated 3D structures of CYPECAD

External loads acting on the structure can be introduced in CYPECAD, Metal 3D or the Integrated 3D structures, so to obtain its optimum design in accordance with the selected code. Additionally, using the Joints I, Joints II and Joints III modules, construction details of bolted and welded connections of rolled and welded I sections can be generated.
By means of the CIS/2 format, all this can be exported to Graitec Advance Steel and obtain a 3D model in the program with:
This way, the project designed by CYPECAD, Metal 3D or the Integrated 3D structures of CYPECAD will have all the facilities and possibilities offered by Graitec Advance Steel available:
Integrated working in AutoCAD, project drawings, workshop drawings (detailing), take-off, CNC file generation for workshop machinery…
Export in CIS/2 format is done using the option File > Export > Export in CIS/2 format in both CYPECAD and Metal 3D. In CYPECAD, all the Integrated 3D structures are exported at once in CIS/2 format.
There are two options when exporting in CIS/2 format:
Requirements for exporting in CIS/2 format
The following aspects should be taken into account for CYPECAD or Metal 3D to export in CIS/2 format:
(*) Common modules: Pile caps, Pad foundations and base plates are operative for both CYPECAD and METAL 3D.
Includes the analysis and design of reinforced or mass concrete footings. These can be square, rectangular, eccentric, corner or edge centred. This a common module for Metal 3D and CYPECAD.
Analyses and designs pile caps for multiple piles. A wide range of types are available. They may hold 1, 2, 3 and 4 piles; linear and rectangular pile caps for any number of piles; pentagonal pile caps for 5 and 6 piles, and hexagonal for 6 and 7 piles. Includes the analysis and design of strap and tie beams. It is a common module for Metal 3D and CYPECAD.
Designs baseplates for any steel column arrangement (simple and composed sections). This a common module for Metal 3D and CYPECAD.
Analyses and designs rectangular (constant or variable) and circular section bars. They may be composed of sawn wood (conifer and poplar species), sawn wood (frondescent species), homogenous glue laminated wood and combined glue laminated wood. It also carries out a fire resistance check.
Analyses and designs welded connections of I sections according to CTE. DB SE-A code and Eurocode 3 of various types.
Designed to carry out an automatic analysis and design of I section bolted connections using prestressed or ordinary bolts (non-prestressed) displayed in the Types of implemented bolted connections.
