AU Opening Keynote

Join Autodesk CEO Carl Bass and CTO Jeff Kowalski as they present the trends and forces shaping the future of making things. Carl will talk about new ways to communicate and even collaborate with our computers, which are blurring the lines between the digital and physical worlds. Jeff will explore how we’re bringing life to design through robust design taxonomies, generative design, and our emerging power to create things that can sense, respond, and collaborate.

Wall Display Quirk

When building a wall with multiple layers built up it is possibly to unlock layers of the wall such that they can be raised or lowered independently of the rest of the wall (the property exposed is “Base Extension Distance” or “Top Extension Distance”).  This feature is invaluable when the need to have a wall finish go above or below the base of the wall, or if the need arises to have the wall modeled up to the structure yet have the gypsum stop short.  However when a layer has been unlocked and that wall is a partial height wall** then Revit will ignore the coarse level of detail and display the unlocked layers of that wall type.

**per the Revit help a partial height wall is defined as

  • Walls shorter than 6 feet (or 2 meters) are not cut, even if they intersect the cut plane.

    The 6 feet (or 2 meters) are measured from the top of the bounding box to the bottom of the primary view range. For example, if you create a wall whose top is 6 feet above the bottom clip plane, the wall is cut at the cut plane. When the top of the wall is less than 6 feet, the entire wall shows as projection even where it intersects the cut plane. This behavior always occurs when the Top Constraint property for the wall is specified as Unconnected.

However if you read into the help file it is only when the wall is Unconnected, so if the wall goes to a level set at the given height or in the image below to a level above with a negative Top Offset then the wall will display as if it were being cut. This can be seen by the different thickness of the lines below as well as the expected display of not seeing the additional layer of the wall.

EVERYDAY BIM

6 Oct

(By Anthony Mc Phee)

How might this approach be used every day for real projects in the real world?

Some general suggestions:

OWNERS:

Restrict BIM demands to things you need directly (e.g. asset management), and to ensure general BIM proficiency (e.g within discipline expectations like drawing and schedules generated from BIM).

Don’t make BIM data a deliverable if you don’t need it yourself, instead include engagement contract clauses that allow for the exchange of data between project participants.

DESIGN PROFESSIONALS:

Use BIM capable software in the way it is designed to be used.

Document how you structure your data and make both the description and data available to others.

CONTRACTORS:

Take advantage of the BIM data available on a project.

Foster BIM processes, along with cooperation and collaboration across project participants.

TRADES:

Embody BIM processes in supply chain and work management. Tailor those processes to take advantage of available BIM data.

Allow others to use the data you produce.

FACILITY MANAGEMENT:

Develop FM solutions that take advantage of available BIM data.

Become involved before facility handover so you can make your requirements known to others.

Notice I haven’t mentioned Standards. That is not because Standards are never useful or don’t have a place. It is because Standards should only be used if they are beneficial; if they assist in achieving the underlying aims. The decision to use Standards has to come from project participants, the ones who create and use BIM data, the only ones who can assess their usefulness.

I hope you find these general suggestions helpful, even if they are perhaps too brief to be truly practical.
