BROAD BRUSH & FINE DETAIL

I spent most of my last 2 years at school painting.  I was supposed to be doing Maths as well, and I had the aptitude, but this was the late 60s and the temptation to "do your own thing man" was too great. (we didn't have dudes in those days)

The past 2 weeks has been an interesting mix of "the broad sweep of history" and the tiny details that make a big difference.  At first sight the topic was "what's new in Revit 2013", but thursday before last, I started my weekend by watching the Autodesk Media Day videos on You Tube.

As usual, the list of new features had left me feeling somewhat underwhelmed.  Gone are the days of huge leaps forward (Mental Ray, Conceptual Massing).  We have entered a period of steady progress on multiple fronts.  (Revit Server, Worksharing, Conceptual Massing, Visual Styles, Materials, etc)

It's an evolutionary process, and if you read up on evolutionary theory you will know that there is a tension between long term & short term gains.  In the longer term, certain changes may be "good for the species", but that will have no effect if they do not also offer immediate reproductive advantages to individuals, so that enough of them survive for the longer term benefits to kick in.  (That was my quick & dirty summary of "selfish gene" theory.)

In the ecosystem that I inhabit, project architects have to meet deadlines.  BIM may be good for the firm in the longer term, but it has to satisfy more immediate needs or it won't survive.  Software companies have to find a balance between delivering features that architects & engineers want "now" and plotting a route towards a future that may well make those blinkered demands totally irrelevant.
To paraphrase the old joke, 'if I wanted to reach an idealised future "BIM world", I wouldn't start from here'.  The reality is even worse, because our destination is not precisely defined. 

If you watch the videos, Autodesk have put down some markers as if to say "we're heading somewhere in that direction"  That's the broad brush part.  The fine detail needs to deliver stuff that people will find helpful on a day-to-day basis, under the pressure of deadlines.  Things like the way things turn transparent when you touch them in Revit 2012, or the trick of adding symbolic lines to the QAT.  qat-qed post
 
Social, Mobile, Cloud.  That's marker number 1 and it doesn't show up much in a list of new features in Revit 2013.  It's there in the subscription benefits: cloud rendering for example.  But it get's more exciting when you add marker number 2.  Suites & Interoperability. 

Autodesk span the worlds of entertainment, manufacturing & construction.  For some time now the huge array of sofware titles that they manage have been leaking features to each other.  A lot of though is going into how to make 1 + 1 = 3.  One of my brightest hopes for Revit 2013 is Showcase, which is a totally separate application.  Could this finally be the viewer that works ?  I've tried Design Review & Navis Works Freedom,  Quicktime FBX plugin, Tekla Bimsight ... People are doing clever things with Game Engines, but I need a quick and easy way of bringing a lightweight export from the model into meetings.

The third marker is analysis & simulation.  More analytical tools available in MEP this time around.  Cloud based structural analysis.  Thermal properties added to material definitions.  Long way to go, so it's good to know that simulation is one of the major long term goals.

SNAPSHOT OF TODAY

I'm sitting in the office. It's ten past 8 and I've got 3 machines working, rendering for tomorrow's submission.  I thought I might share this image that I just cooked up.  It's a combination render/shaded view of a typical balcony for the apartment building we've been working on for the past few weeks.  Took me maybe 20 minutes to generate this image including render time.


The shaded view was actually part of a study sheet that I composed a couple of days ago.  I love doing this kind of detail sheet in Revit, combining orthographic with perspective, and getting into the nitty-gritty of how something is going to be built.  We're still at schematic, so I'm notsizing every member of the railing yet, but we're starting to consider how things fit together.


Here's part of another sheet in a similar vein, looking at the access walkways.  It's a single loaded scheme with open-sided walkways.  We're not really happy with the way these look yet.  Need to do some more studies when we move into the next stage.



Another slightly processed render that I've been working on while typing this post.  This uses the old trick of blurring the top layer then masking it out so that the centre of the image remains sharp.  Also the edges are greyed out more than the centre. 



And finally a study sheet that came out of discussions with the Structural Engineer.  Some tricky junctions and transitions between the podium level and the parking grid below, not helped by the fact that there are lots of 45 degree shifts in alignment going on.  Revit is a fantastic tool for visualising this kind of situation and gradually making adjustments to try to optimise the various trade-offs that inevitably need to be made.


Back to work now.

QAT & QED

Quick Access Toolbar.  Picture below from my first post back in Oct 2010, and I'm still in love with this layout.  Saves a lot of switching tabs.



But check out the pictures below.  Spot the difference ?


For far too long I have been cursing and swearing because you can't do a "create similar" on symbolic lines in family editor.  Why do I have to keep switching to the annotate tab ? Too many clicks, it's disrupting my workflow !

This weekend the penny dropped.  Just add symbolic lines to the QAT.  At first I worried that it would be confusing if I placed this next to "detail lines".  But of course they grey out, depending on context.  The giveaway in the first picture is the "Load into Project" button, which tells you that it's a snapshot from family editor, whereas picture two is from the project environment.


I'm so happy now.  Little things can make a big difference.
