Revit: limited access for "Project Managers"

Solution provide by Steve Stafford for Tim Ulrich, Houston:
You need access to your Revit model and don’t want to interfere with the live project model or are concerned about altering any work that has been completed thus far. List of Steps:

1. Open Revit
2. Open the project and select Detach from Central
3. Click OK to accept warning message
4. Inspect the model – do what you need to do
5. Close the file
6. Close Revit

In-depth Explanation:
Open Revit: Double-click the Revit Architecture 2008 icon on your desktop.Open the Project: Click the File menu > Open. Now use Browse to the server and folder that your project files are stored in. You can check with your team’s data leader for precise location information. THIS NEXT STEP IS THE MOST IMPORTANT! Check the Detach from Central check box!

Inspect the model - As a project manager it may be unrealistic to expect that you become completely savvy with Revit. It is completely realistic to expect to be able to poke around your project so you can stay involved and connected to your team’s progress and how the model and documentation is tracking expectation. You may need a quick review of how to open views, spin a 3D view, print views or sheets.

Close the File: If you choose the File menu > Close Revit will close the project file without saving anything you have done. In fact the entire time you have been working within the project you have been working in a temporary file, with no name at all. If you decide to save anything you have done you must use File menu > Save and choose a directory to save the file in. You must NEVER save the file in the same folder as the actual project or use the same name as the original.

Close Revit: File menu > Exit

UPDATE: December 2013:

Now, Autodesk provides a "Revit Viewer" that is installed with the regular version of the application. This will also allow a team member to view a model without fear of interfering with the active project team.

Revit: Exporting Revit to AutoCAD

Solution by Lee Miller to suit our HOK Cad Standards:

1. Once the view is ready for export, simply go to the File pull down and select Export a DWG, DXF, DGN. Select DWG.

2. You have the option of saving the Revit View in either an AutoCAD 2007, 2004, or 2000 file format. We typically save to AutoCAD 2004 file format for AutoCAD.

3. You can also select multiple views, i.e. each level’s Floor plan, by changing the Export Range from Current View to Selected views/Sheets.

4. The export Layering scheme is set by default to V:\RAC2008\HOK Support\HOK Export Layer Dwg.txt. In most cases, you can select the existing standard If you are not exporting to HOK standards, you will need to create a custom one.

5. Finally, you’ll have to pick a directory where the DWG file will be saved. Create a folder in the Revit project directory under Publish\Background. Make sure to create a folder in the following format: YYMMDD – Description.

Revit: exporting images to file

We are having issues exporting jpeg, tiffs or png images from Revit isometric views. We setup the view in the normal way and then go to export images from the file pull down menu. Set the resolution etc; however Revit seems to go through the process of exporting but when you go to the location you thought you had saved the export, you find that there is nothing exported. We have tried various different file formats, but with no success.

Solution from Kevin Parks that provides standard procedure that can be followed:

1. Select File / Export / Image...
2. Name the output location and provide a file name or it will go through the process, but no file will show up.
3. Select the Zoom to button and chose a percentage. Ex. if you chose 200% than your output will be (Raster Image Quality x 2)
4. Chose your file format, typically PNG for high quality. If you chose JPG use the lossless option.
5. Also, chose the Raster image Quality. Ranging from 72 to 600.

PLEASE NOTE: The output image on your monitor is only 72 dpi max. Print the image out on paper before making a judgment call on the quality of the image. HOK CAD Solutions - video burst

Workflow: Revit to Max optimisation

Here are some good suggestions from Juan Carlos Arias and others for Revit > Max workflow:

Materials: All the geometry in the model should have a material previously assigned in Revit (especially families) in order to allow the use of the dropper tool in the material editor to select and change the material globally in Max.

UVW Mapping The UVW mapping of the geometry in max is generated by the work-plane in which the geometry was created in Revit. This is a very important factor to be considered in the creation of new families.

Geometry and number of faces/triangles: My advice in this matter is the proper use of worksets. For example, for the exterior renders we have been using three worksets: Shell, Core, and Structure (slabs, columns, and beams). In this way we ensure that only the geometry necessary for the creation of the exterior render is linked to Max.

Mental Ray: Distributed Bucket Rendering “DBR” is the optimal approach. Mental Ray allows you the use of up to 8 CPUs for a render of a single frame.

Enhancements to File Link and DWG Import Revit 2008 users can import projects into 3ds Max 9 Extension: Productivity Booster using the DWG format. This format encapsulates information about geometry, material, lighting, rendering properties, and cameras, streamlining project data exchange across multiple applications. This extension includes enhancements to DWG import performance, reliability, and ease of use.

Meanwhile, while we are trying to figure this workflow out Michael Ruiz a self confessed fan of Accurender is producing some great images inside Revit without the need to link to Max!.

Revit: how to dissallow wall join

Question from Nekia Strong.
I am working on an office project that contains a series of vertical penetrations surrounded by a 2 hour shaft wall. We are looking for ways to get Revit to understand that this wall type must be closed off from other walls types. Does anyone know how to unjoin different wall types so that, in plan, they cleanly align and do not try to automatically wrap the finishes around each other? I have tried to simply disjoin them at the corners and keep getting strange offsets and gaps. Also, will the room command still work within a room made of non-joined walls?Please let me know if you know!


Solution by Lee Miller:
To unjoin the wall, it’s easier to grab the blue grip, or the wall end control, and move it away from the connected wall. Once the wall end is not connected, right click on the blue grip and select “disallow join”








Then you align the wall end to the wall without joining it. - Drag wall end to wall.











The wall should cleanup.










Walls with disallowed join are not affected by room bounding. This is a separate wall parameter that needs to be turned off. (Ed how is this done?)
