SteelVis (CIS/2 to VRML Translator) Web Services version


Overview

The CIMSteel Integration Standards (CIS/2) is the product model and data exchange file format for structural steel project information. CIS/2 is intended to create a seamless and integrated flow of information among all parties of the steel supply chain involved in the construction of steel framed structures.

From this web page, a CIS/2 file can be translated into a 3D interactive model in the form of a VRML (Virtual Reality Modeling Language) file that can be viewed in a VRML viewer or web browser plugin.


1 - Select CIS/2 file
2 - Set Display Features

Generate Coordinate Axes
(For debugging)

In a Detailed Model for each:
Assembly 
Part 
Bolt layout and weld 
Hole layout

In an Analysis Model for each:
Element

In a Design Model for each:
Design part
3 - Generate VRML VRML text file (for saving, debugging, error messages)
VRML model for viewing (requires a VRML plugin or viewer associated with the web browser)

 

Notes

By default, the CIS/2 file is translated to a VRML text file. The translation process can be verified by checking error and warning messages at the end of the VRML file.

The resulting VRML can be saved in a file by copying and pasting the VRML text into a text editor. Edit the file to remove any HTML tags at the top and bottom of the file. The first line of the .wrl file must be #VRML V2.0 utf8   The file must be saved with an extension of .wrl where the last letter is an 'L' not the number '1'.

Disclaimers

SteelVis checks for many syntax errors and should create a VRML model that looks correct, however, it does not imply that the CIS/2 file conforms to the CIS/2 schema. A VRML model that looks correct also does not imply that the CIS/2 file follows recommended practices, software implementers agreements, or that it can be imported into other CIS/2 applications.

VRML models that look wrong might be caused by cross section dimensions that are not explicity specified in the CIS/2 file. SteelVis will lookup, parse, or approximate those cross sections. Check the error and warning messages at the end of the VRML file.
