BIM 360 info & Autodesk 360 Viewer

I’m excited by where BIM 360 is going. Its worth reviewing this article at Jeremy Tammik’s The Building Coder blog. It’s a useful insight into the direction of Glue & Field with regards to API access…..& this is only the beginning. Watch out for some interesting developments going forward….

One other thing, be sure to read up about the new Autodesk 360 viewer at Ken Walmsley’s Through the Interface blog. I’ve had a good play with this & its very impressive.

File Upgrader – Revit 2015

From experience its about this time when Revit users / BIM managers start to look at deploying the latest version of Revit; a service pack has typically been issued & things are slowly settling down. One thing you are going to want to do is upgrade all your content to the latest version. People use various tools such as batch files, journals etc. But can I suggest you take a look at Revit File Upgrader from Harry Matterson @ Boost Your BIM? Harry released a 2014 version which you will find on the Autodesk App Store.

However, he has also released a awesome 2015 version, it does exactly what it says on the tin! Harry has given it away for free; so be sure drop by his website & thank him. You can download it from here.

Revit 2015 – Trim / Extend Multiple Elements

This is a reasonably simply improvement. If you are laying out a lot of walls, quickly being able to trim & extend so they cleanup is an essential requirement for any designer, especially if they have come from a CAD background. Over a number of releases we have seen usability enhancements which have migrated their way to the Revit platform, based on tried & tested CAD methodologies. For instance if you have ever used AutoCAD you might have used the fence command. In Revit 2015 you can now use a selection box to select multiple elements to trim or extend to a boundary defined by another element. Note; you are still able to select individual elements to trim or extend. The video clip below shows the functionality performed on walls, but it will happily work on other elements such as structural beams. A simply, but time saving, valuable enhancement.

Revit 2015 – sketchy lines

Sometimes when using BIM for presentation purposes, especially during the design development stages, the digital outputs can look a little too polished. In the past an architect might of used hand drawn sketches & diagrams to convey the design. New for Revit 2015 is the Sketchy Lines feature which emulates a hand drawn visual style. This feature is available to be applied to any graphic display style including 3d views, perspective views, elevations, sections & plan views.

You can adjust settings for Jitter and Extension to create unique interpretations of any visual style as shown. The Jitter slider allows to vary the weighting & clarity of the line as if you had drawn it with a pen or pencil, where as the Extension slider allows you to how far lines overlap at intersections. Check out Tim Waldocks detailed overview for more examples of how this feature can be used.

Faster….Faster…..Revit 2015

train motion blur

As I noted in my previous blog post about Revit 2015, it has got faster. It feels faster to use, which is very welcomed. These are the performance enhancements suggested, but not actively highlighted.

First speed enhancement; Faster drawing of elements in views. What they have done according to what I have read & experienced is that Revit now amalgamates the drawing process so that elements are drawn in larger collections to enhance overall performance. The example that was explained to me was when you draw say 100 walls, Revit would require 200 drawing calls. In Revit 2015 it now draws the same walls using only 2 drawing calls. The overall impact of this is that redraws are substantially faster & it also makes the navigation of views faster.

Second speed improvement is that you also get Faster selection Graphics; what does this mean? Now, if you were to select a large number of elements in your model, Revit 2015 uses a new process for displaying the selected elements. Again, the outcome is improved overall performance for displaying the selected elements.

Thirdly, improved performance in MEP views. Not being an MEP user myself, it has been known for sometime that Revit MEP has been laggy, especially on large datasets. SO in Revit 2015, the underlying technologies used to display MEP components in view has been enhanced, resulting in improved performance when opening & closing & working in views. From my experience, whilst not exactly scientific, I would concur with these points. It does indeed feel & perform better. This can only add to the overall user experience. I am sure we will see more of this subtle, but essential framework performance improvements going forward.
