Publishing BIMx in AC20

One significant change to AC20 is the output method for saving a BIMx file. We can no longer simply save a BIMx file from a 3d window. We now need to use the publisher to save BIMx, which means we need dedicated View Map content for our BIMx files.

One of the big questions I get is ‘why is my BIMx file opening in a random location?’. This is most frequently caused by the view the BIMx is being saved from not being updated from the current 3d view.

Lets go through this step by step.

  1. Save the desired camera’s AND 3d view to the View Map. You can use the Organizer to save the camera path(s) you want to include in the BIMx file for animation or still gallery views. It is important to note that the 3d View that will generate the BIMx file needs to have the correct view settings, cutting planes, marquee, elements, and view location/orientation/position saved in the view map.screen-shot-2016-09-23-at-11-57-23-am
  2. If you have a view already dedicated to BIMx in your view map, but it is not exporting correctly, you may need to update it to include view restrictions such as marquee limitations.screen-shot-2016-09-23-at-12-12-05-pm
  3. Make sure the Publisher Set dedicated to saving BIMx is set up properly. You want to make sure you are Saving a local copy with a correct destination. You do not need a Graphisoft ID to save a local copy, but you will get some warnings when publishing- more on that later.screen-shot-2016-09-23-at-11-58-26-am
  4. Using the organizer, Add Shortcuts or drag the views for BIMx and BIMx Gallery items to the BIMx Publisher Set.screen-shot-2016-09-23-at-11-59-00-am
  5. Set the Options for the Camera Path to either Separate gallery items or a Single Movie for the gallery.screen-shot-2016-09-23-at-11-59-08-am
  6. Set the 3d View to publish as is, or with Global Illumination. Note that publishing with G/I selected will take as long as a typical BIMx file previously took to generate global illumination. This means you will be unable to use ARCHICAD while it is generating the BIMx file. There is also no longer a way to generate G/I after the BIMx file has been published.screen-shot-2016-09-23-at-11-59-16-am
  7. Now you are ready to publish. You can use the Organizer/Publisher to save out just the selected 3d view and camera or the entire set.screen-shot-2016-09-23-at-11-59-28-am
  8. Here is where you get the error messages, since you did not put in a GS ID (which you would only need if you were going to share a Hyper Model, not a WWA Standard at this point).

One last thing to note; you will no longer be able to Save BIMx files. This means you will need to plan ahead when presenting BIMx for a client meeting. Open the file ahead of time to set the sun shadows, position, starting point, navigation speed, or any other post-publish settings that you need to have as part of the presentation.
