Create Family clearances that will can be controlled in Navis and Revit<data-blogger-escaped-o:p></data-blogger-escaped-o:p> <data-blogger-escaped-o:p></data-blogger-escaped-o:p> In some projects you are asked to show clearances for equipment. So you may think fine I will draw a box to represent the clearance and it will grow with the component etc. Before doing so think about a few things. Do you need to be able to segregate or turn off this Clearance in Navis Works or produce Views that can control it in Revit. Here are some options for you.<data-blogger-escaped-o:p></data-blogger-escaped-o:p> First Create a Sub category in the Family level that you will use throughout the project as the Norm or create this name at the company level so that in any project this is a recognizable name. If you have variables of this name, it will be case sensitive and you will gain additional instances in the Project.<data-blogger-escaped-o:p></data-blogger-escaped-o:p> <data-blogger-escaped-o:p></data-blogger-escaped-o:p> Now create the standard definitions of line type and color to signify your clearances. You can also define a custom material at this level. The Next step is to draw the shape for clearances. Assign the constraints to the shape ...

With the Hilti Button for Firestop, AEC professionals can populate Building information Models with appropriate firestop components easier than ever, through automated clash detection and product selection. The Hilti Button for Firestop is an add-in for several Autodesk applications such as Revit, AutoCAD MEP, Fabrication CADmep and Navisworks Manage. Hilti Button for Firestop automates the entire firestop BIM process by identifying and qualifying penetrations, as well as recommending UL-listed firestop systems, saving you time and giving you the documentation required by fire-safety building officials.

I am very visually oriented.  I like to see what I am modelling.  However, when it comes to Spaces within RMEP, you couldn't see what you are really doing. While there is a model view of Spaces within the built-in analysis interface, I still had difficulty exploring to see where I may have missed placing Spaces or where Spaces were overlapping one another. Now, working between RMEP and Navisworks, the Space model can be visualized.  Start with the settings for Revit NW Exporter and/or NW Reader:Navisworks Option Editor for Revit File Reader  Findings as I was exploring this feature:  You do not need to check the box “Convert room geometry” which is to convert the Spaces to construction parts.  Either way, the Spaces show up.  If using the NW Exporter from Revit, I still needed to have a 3D view as the active view when I issued the command.  If you have a Plan View up, example Level 1, then I found that my Level 1 Spaces came in flat/2D while Spaces from other floors were 3D.  You do absolutely ...

For an overview of the new features and enhancements for Navisworks 2013, see the link: http://usa.autodesk.com/navisworks/features/My Favorite New FeatureGrids and Levels from RevitIn the past we had to do a lot of setup to get grids and levels to display in Navisworks, particularly difficult to acquire from Revit.  3D Grids were introduced as a Family that helped to go from Revit to Navisworks.  Now in the new 2013, standard Grids and Levels will pass over to Navisworks.  The only specific setup that I have found to have this feature work: The grid must be native to the project; you cannot just have the grid displayed from a link.  Also, to get the Level information, you need to have at least one grid line. Revit Grids and Levels show up now in Navisworks 2013My First Bug FindNavisworks Revit File ReaderWith 2013 you can now read a RVT file just like you can read an AutoCAD DWG file.  Fortunately, the folks at Autodesk did not take away the Revit Plugin so that we can export from Revit to NWC.  I write ...

Sorting the objects in Navisworks based on Properties such as System Classification or System Type as assigned by Revit MEP is a common practice.  The sorting is used in Clash resolution as well as Timeliner and for visualization.  However, at times even the System sorting is too ‘comprehensive’ and since the model was organized by Worksets, why not use Worksets then as our Filter property?  Be prepared to analyze your Workset data in Navisworks to determine what the appropriate value to filter will be.  The Navisworks exporter from Revit converts the Workset data to Integer values.  For an example, the default Workset1 “appears” to always come over as the integer (zero).  (NOTE:  I wrote ‘appears’ because, so far, every test I have done it has set the Workset1 to the integer zero.  But I don’t want to say it will do this each and every time, until such time that I am convinced it will.)For my examples below, I have an NWC written from RMEP with the standard worksets: Shared Levels and Grids –and- Workset1.  While in the ...

In previous posts on this blog, we have reviewed two methods that can be used to slice up a Revit model by Level designation: 1) Using the built-in “3D View For Levels”  and 2) Using the “DPR Slicer”.  One reason for slicing up the model is for Navisworks, particularly the Timeliner.  Timeliner provides the means to build an animation of the building process.  Revit does OFTEN apply Level property information to objects as they are placed.  However, too often the Level designation information is assigned as -or- there can be no level designation –or- if an object spans multiple floors, it will get associated to just the one floor from where the object ‘started’.The following slides show a model where Filters/Search Sets were generated based on the properties Level designations. Highlighting Level 1 showing spanning to multiple floors   Highlighting shows those objects who are designated at Level 2  Highlights are Level 3 designated    Highlights of all SearchSets reveals a roof still to be assigned  Now take a look at how the Navisworks Layers designate the ...

The Batch Utility can be used to automate importing and conversion processes that are common tasks within Navisworks. There are four areas that the batch utility can assist: getting a list of design files used in a current NWF/NWD, build a new NWF/NWD with selected design files, export out NWDs for each design file listed, and accessing the Windows Scheduler to run the batches. As an example, I will select various NWCs to build a new NWF.The Batch Utility is accessed from the Home Tab: First, in the Input section of the dialog, I will select a specific NWC file that contains all the architectural models using the Add Files button:And as well, I can specify an entire folder of any supported file type using the Add File Spec button. Just above the Add File Spec button is where you can pick from the file type wildcard list. In my example, I will select all the NWCs within my FIRE folder:Next, on the Output section of the dialog, I will use the As Single File tab and enter in ...

My favorite feature of 2012 Navisworks Manage is the Appearance Profiler. It can be used in conjunction with Search Sets to color-code your coordination models. The nice thing is that the settings can be saved out and recalled as needed in the Navisworks NWF file which makes updates to the model much easier. Pre-planning, particularly in file naming conventions, will make this feature update even with the introduction of updated models from the CAD programs. In the figure below, I built search sets based on the file names. Then I assigned those search sets to colors and level of transparency. My architectural model is green and transparent, with electrical in red, ductwork in blue and steel in yellow. Last step, SAVE the profiles listed in the Appearance Profiler to a DAT file that can be imported to any NWF when needed.

Several times this has happened to me, where Navisworks will get stuck in "selection mode" which prevents me from selecting any of the viewing functions from the Navigation bar. I recently was teaching a class, where several folks in the class had the same problem. I have tried several actions to clear the problem and have found the most reliable: right-click in the background and select SCENE. Seems to clear the problem everytime.
