3D View to 3D Document

The view map should include a source view associated with each 3d document. This is true for reflected ceiling plans, detail axons, whole building foundation diagrams or any other view where view and content will need to be maintained and updated. In this post I will explore creating a foundation axon document that can quickly be updated to add new foundation elements, both 3d & 2d, without losing previously documented content, alignment or view settings.

The 3d view that a 3d document is created from should come from a camera or saved 3d window in the view map for consistent view angle creation. It should be saved to the view map with predefined view settings; if a layer combination doesn’t exist for the content you want to see, create one. The view settings should not be set to “custom” for any of the view map settings.

Additional view content restrictions may be applied, but difficult to replicate if the model or content change. Things like marquee restrictions, cutting planes or filter and cut elements in 3d can be difficult (but not impossible) to replicate when the 3d document needs to be rebuilt from a source view. To ensure these settings can be duplicated with updates to 3d model/document content, these settings need to be documented, such as hotspots and marque or cutting plane locations or screen shots.

One tool that can be invaluable (and is widely underused) for 3d document rebuilding is the selections palette. Once you have the content isolated in the 3d window, select it and save it to the selections palette with a name that relates to, or matches, the view map name for the 3d window or 3d document.

Selections

Using this palette you can open the camera view, re-select the original elements, add any new elements to the selection and isolate in the 3d window. The selection palette should be updated for future use with this new selection.

Now just redefine the 3d document (in the project map > 3d document settings) with current window settings and your document will match the original camera angle, cone, and drafted content alignment; but will include the new model elements.

3D GRID MARKERS

This is a three post kind of day; I guess this is me finally making up for missing a week to spend time with my new baby girl. In any case, you’ll have to suffer through one more bit of information today. At least this one is quick and simple though.

If you are using grid markers in your 3d documents you may find they are oriented to the plan view; which in most cases is not a readable orientation. There is a setting to orient the text to the orientation of the Perspective Projection.

SCHEDULING OBJECTS AND RELATIONSHIPS TO DRAWINGS

Leveraging the full power of BIM yields quick & coordinated results:

We have many great schedules at our finger tips, already created and waiting in our template.  Remember to leverage the use and creation of new schedules as documenting tools throughout the design and documenting process.  The images below show a sample foundation plan, possible 3d document associated with it.  These views were mocked up and saved in about 3 minutes using our template favorites.

The question was posed today; how can I quickly reference these elevation markers in a list format with out the need to manage and update duplicate information?  The quick answer is with a schedule.  The schedule below will become available as part of our new template for those who need to list off any spot elevations on plan, elevation or 3d views.

Where do I start when I want to schedule something?

I know I have discussed this before, both in person and on other blog posts, but like most good BIM workflow concepts things stem from the questions “what should be 2d and what should be 3d?”

The answer is always that if it shows up more than once it should probably be modeled.  In the above case, we have a simple spot elevation tag or datum.  This could easily be shown as a 2d symbol on the floor plan, but then the text is in constant need of babysitting and updating.  If we use the readily available 3d marker we can place it in the 3d view, review its location and contents in the 2d views. As a bonus we can scroll through a schedule list to confirm that all datum markers (and consequently the objects they are placed to) are in the right place.  Adding this little bit of additional information to your model helps ensure the level of precision is where it needs to be as well as opening up a huge range of documenting possibilities with little or no additional manual coordination.
