look at the scope of work

Scope boxes control de visibility of datum elements. Grids, Levels and Reference Lines can be associated with Scope boxes, and the name of user created scope boxes are listed as an instance parameter in the datum properties. This is useful when we want to display datum elements in certain views but not in others.

Today in class, a student associated the levels to a scope box. After doing this, the levels projected in his South Elevation dissapeared.

The not-so-obvious reason was this:  The south elevation plane was NOT intersecting the scope box, therefore, preventing the levels to be displayed.   Remember that datum elements associated with scope boxes will only display IF a cutting plane intersects the scope box.

Horizontal Glue

Imagine the following design team:  A designer based in Mexico, a structural engineer based in Canada, a MEP consultant based in London, a contractor in Boston, and +20 specialty consultants dispersed in the United States. The challenges of such a team appear to defeat even the most diligent and organized project manager.  The search for a silver bullet capable to overcome the ineficiencies of geographically dispersed teams remained, in my opinion, an idea still years ahead to come.  Well, not anymore. I sat on a presentation of 'Horizontal Glue' yesterday and if I am asked to describe the tool in one word, i'd say:  Amazing.

Horizontal Glue is new little known, powerful web-based technology that translate the traditional BIM workflow to the cloud. It merges up to 40 different types of model formats, including the well-known .rvt .dgn .dwg into a single composite model accessible to anybody around the planet via a browser. Users, including crew workers and subcontractors, can access the model and run multi-model interferences, exchange datasets, identify hard-clashes, associate the model to construction schedules & estimates, and build 4D animations. Project designers can mark-up coordination issues on the fly, using their browser and no more, and link them to a web based RFI form that is emailed as a hiperlink to consultants for resolution. Modifications to the composite model are allowed, both physical and parametrically, and changes can then be synchronized with your in-house model via a REVIT plug-in. The integrated model can be accessible in the construction site using an Ipad application, which in turn generate reports and action items distributed to the team thanks to the partnership with 'Prolog', the information management tool by Meridian Systems.

Check their website on http://www.horizontalsystems.com/index.php/products/glue-platform.  We will be using the tool for a large project in our office and I can't wait to have a grip of the tool in my hands.

Plines in REVIT

Unlike most CAD based programs, REVIT lacks the ability to produce Polylines.
I miss this functionality,  which always prove useful in detailing and outlining wide line section edges.
Visibility graphic settings just won't get us there. A workaround i found today is to use a 'hollow' Masking Region.
The trick is to create a Masking Region, and override the region properties (via right click mouse) 'by Element', switching on the 'Transparency' checkbox.  The region preserves its boundary lineweight without the solid white pattern.

Imagining Risk

In a radical departure from centuries-old tradition and norms of architectural design, the new digitally generated forms are not drawn as the conventional understanding of these terms would have it; they are calculated by a chosen generative computational method, which is the base of a parametric design, an approach that bridges into the field of computer programming.  It is the parameter what is declared, not the shape, the form or the envelope.  By assigning different values to the parameters, particular instances are created from a potentially infinite range of possibilities.  Pencil is replaced by equations, which in turn are used to describe the relationships between the objects, thus defining an associative, linked geometry.

The objects establish relationships based on formulas, and how these interdependences are established depend to considerable extent to the architect's ability to craft them precisely. Instead of crafting a 'concept', we now craft 'relationships' and 'controlled behaviors', which shape the path to discover new form: The determinism of the precise traditional design is abandoned in favor of the unpredictable and unexpected, which often paves the way to poetic invention and creative transformation.

The risks at stake are high: non-linearity, indeterminacy, and unpredictability are anything but certain.
