Bentley's Structual Sync must be installed on both the RAM and Revit workstations, and the ISM plugin for Revit must be installed on the Revit workstation.
Once the model is constructed in Revit, use the Bentley ribbon to export and import model data. In RAM, there should be a new menu item "ISM" available under File.
Instructions for modeling in Revit:
2. Create worksets for RAM elements. (In my current model, I added RAM Framing, RAM Floors and RAM Grids in addition to the normally used Structural worksets. If you already have a model, when moving members to new worksets, Right Click and "Select All Instances Visible in View" is your friend. Also, Beam Systems can (and should?) be moved to RAM worksets.)
3. Create model, using as few member sizes as possible (you will see why when you get to step 8). As this will be exporting into RAM, use the minimum amount of levels necessary, and do not offset elevations for decks and joists.
4. Create a Plan View that shows all elements, but only worksets that will be exported to RAM modeler.
5. From that plan view, select all objects, then from the Bentley ribbon, select "Create Repository"
Check the "Use Revit Current Selection" box and create an ism.dgn file where the RAM software can access it (ie the Project directory). Hit the "Next >" button to start the process.
6. You must now map the Revit elements to ISM elements. I will describe the instructions as they appear for me in my particular model.
7. For Materials, there are two unmapped steel types, indicated by the X next to the types. Hit the "Match All" button and ISM Revit Link should be able to fill in the materials for you. (If not...Highlight the first Revit material, and if there are no matching materials from the dropdown list under "ISM Materials" to the right, select the "New Material" button. Select "Steel" and hit OK in that dialog, and the Steel (947-521) material will fill out. Change the other steel materials to the same.)
Hit Next once all materials are matched.
8. For Column/Framing Section Export Mappings, highlight Wide Flange Column, then select "Table Section" from the "ISM Section" Type to the right. Table Name and Section Name will fill out below. Change Table Name to AISC, and then select the appropriate Section Name (W10x49 in my case).
The process is the same for Wide Flange Beams and HSS members. For bar joists, the Table Name will be "Table Joist" instead of Table Section. Hit Next once all members are mapped.
***Edit - You must select the search tables before Match All will work -
9. Surface Member Export Mappings maps the floors (and walls). "Match All" appears to find Composite Deck information easily. New Material has a Steel Deck option that fills in material information. Next to continue...
10. Dialogue box changes to "Data Export Progress" and it looks like you are done but you must hit the "Export >" button to proceed.
11. Structural Synchronizer will open, this shows what elements are being modified from the previous ISM version. Status and Change for all members is automatically set to "Added" and "Accepted" for new files. Hit the Update button and an unfriendly dialogue box will appear prompting for a "Commit Message". This box prompt should be "Enter Changes" or similar. For now I type in "Initial model export" and hit OK.
12. After a few seconds 'Some data warnings/errors occurred. Click Show Report for details.' I check the report and have 108 framing items that did not get a material set. (These are steel bar joists that have material set to
13. Hit Finish.
14. From the RAM Modeler, Under the File menu pulldown, select ISM and then "Create from ISM Repository"
15. Run an Integrity Check and marvel at how few errors you have (compared to dxf import).
16. Be aware that the Revit model, the ISM file, and the RAM rss files are all separate. The Revit modeler and RAM designer should take care not to make changes to their models that will be undone by one another.
