So with the latest Star Wars movie coming out soon I was inspired to toy with the idea of modeling a full scale Revit family of the AT AT. Originally it was shown in the Empire Strikes Back. This was one of my all time favorites. While taking this project on I see that there are some valid challenges in creating some of the geometry. So if you ever want to improve your skills on creating families this is a fun way to not only make something cool but to improve your skills. I under- laid flat 2d images and scaled them up for reference. the rest is purely improvising. I enclosed some preliminary images. Check back later and I will post my progress pics. Remember have fun. Enjoy!.

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 ...

"Well, how did I get here?" One of my favorite verses from an iconic Talking Heads tune. And one that applies to real life more often than I'd like sometimes. When Autodesk released Revit 2013 they added a new "feature" that took a lot of users by surprise. By simply double-clicking on an instance of a component family, like a door, window, furniture component, etc., you would be placed in the Family Editor in that component family's source file, ready to edit. I'm not sure how this "feature" found it's way into the software, or who the person was that thought it was a good idea (I think they might need a little Revit training), but the user community by and large was up in arms over it. I mean... really... select an instance of a component family and take a gander at the ribbon - what do you see? What is so hard about simply clicking "Edit Family"? On the other hand, many new users have "double-click-itis" - and when that happens on an instance of a component family, they ...

After installing Revit 2017 I noticed every time I opened a template or out of the box family it had to upgrade from 2016. I found some help online that pointed out a good solution to be able to control Revit content. If you accidentally saved over your OOTB families or have missing families. You can uninstall and repair the content. I went as far and removing the Metric database to speed things up. 

Sometimes you discover something and your first reaction is a bit of embarrassment because you didn't already know it, followed by amazement that nobody else has ever mentioned it to you before, because it's potentially a REALLY big deal. In today's previously unknown-to-me potentially REALLY big deal department: Did you know that you can accidentally delete multiple family types simply by opening and saving your Revit family? It's true. Here's how it happens: 1) In a Revit project, a conscientious BIM or Model manager performs a Purge Unused, purging unused Family Types, in an effort to keep file size down. This is good practice. 2) At some point in the future, from the same project, a user selects an instance of a family on which the above-mentioned purge was done, and selects "Edit Family" from the Ribbon (or double-clicks on the family instance to go to the Family Editor - who's boneheaded idea was THAT feature, anyway?).  3) The user makes a minor change to the family, then saves the file. *Poof* - all of those family types that were purged in the project are ...

The great majority of manufacturers who are developing families of their respective product lines, are building the families for architects rather than engineers.  As a result, often the families developed cannot be used in a RMEP project due to the need for RMEP objects to be Face-hosted rather than ceiling-hosted, wall-hosted or floor-hosted.  In the past, engineers needed to rebuild families to use within the RMEP project.  Not any longer.  Now we can use the Copy-Monitor function to accomplish the conversion.Below you will see where I have placed some walls to allow the mounting of the wall-hosted light families.If I select one of the lights, take it into the Family Editor, you can see from the Properties that the host object is a Wall.Next, I will start a RMEP project and link in the model with the wall that hosts the light fixtures.  And then use the Copy-Monitor function to Copy one of the light fixtures.Upon completion of the Copy-Monitor function, by selecting the light fixture, you can see that it is a monitored object and resides natively in the ...
