Revit Data Corruption

By Elyse Hatch , Technical Consultant – AEC  at SolidCAD

 

Let’s talk about data corruption in Revit. In this post I will look at these 4 points:

  1. File crashes before opening
  2. Crashes when opening a new view
  3. Looking for corrupt families
  4. Higher level investigation

As always you should make sure you save a copy of your file for testing while trying to resolve corruption issues.

File crashes before opening

Sometimes a file cannot open because of a simple issue that can easily be overcome. Each of the following actions have the potential to get past a different issue. If your file crashes when you try to open it ask yourself:

  • Can the file be opened with or without audit checked?
  • Will the file open without the worksets loaded? Can I narrow it down to a specific workset that keeps the file from opening?
  • Can I open the file in a different build, or a newer version of Revit?
  • Sometimes new name allows you to bypass the issue, copy-paste file to new location
  • Isolate the file from the network save to a location where the links cannot be accessed.

Crashes when opening a new view

If your file crashes when you try to open or create new views, try these suggestions:

  • Turn off hardware acceleration try each location one at a time.

  • Reset Revit settings
    • Customized settings are stored in the app data folder, when removed from this location the defaults are regenerated.
  • Repair the installation
    • This won’t change any user setting.
  • Open Revit without add-ins
    • Locate the following folder: C:\ProgramData\Autodesk\Revit\Addins\[Version].
    • Temporarily move the addin files from the folder above to another location.

If any of these work for you take note, this is where the issue resides and you’ll want to know the exact cause whenever possible.

Looking for Corrupt Families

Sometimes the behavior you see in a file is caused by corrupt families follow this process to identify corrupt families.

  • Save a copy of the corrupt file
  • Open and save all families as a library, this process will fail when it reaches the 1st corrupt family.
  • Record the family named on the bottom left hand corner of the screen & delete the family and run again, repeat until the process completes successfully.
  • Open the original corrupt file and reload all the families on your list with versions that predate the corruption. If you’ don’t have a previous version of the family, you’ll need to recreate them.

Higher level investigation & troubleshooting

Many issues can also be fixed by returning to Revit’s original settings.  Try these steps one at a time, testing the file after each change.

  • Rename the .INI file (_old) which is in the AppData Roaming folder.
  • Rename App Data Folders (_old)
    • C:\Users\<username>\AppData\Local\Autodesk\Revit\Autodesk Revit 201x
    • C:\Users\<username>\AppData\Roaming\Autodesk\Revit\Autodesk Revit 201x
  • Rename Workspace in the registry editor

 

When these folders/files don’t exist, they are recreated the next time the user opens Revit. Be sure rename and not remove these files/folders, as they will server as backups for the user original setting including keyboard shortcuts and font maps.

Happy Reviting!

Making more beautiful, realistic, and detailed renders in Revit

By Thomas Morrissey, AEC Technical Consultant at SolidCAD   

3D visualization is an essential part of architectural illustration today. Renders allow you to communicate your vision and intent to clients and colleagues. This is why models or drawings are often sent out to be professionally rendered. This is an expensive but usually necessary process. However, it is possible to make high quality renders in-house using Revit or through the cloud.

What makes a beautiful render? Like many things, beauty is in the eye of the beholder. It is in the nuance of the materials you select, the lighting, the details you choose to include, and any post-production editing.

Here are a few thoughts on how to start making more beautiful, detailed renders in Revit.

I’ve wrapped them all up in a short video at the bottom of this post.

Energy analysis – Realize the greatest benefit of BIM

By , AEC Technical Consultant at SolidCAD                                   

Many engineers do not realize the power of Revit and prefer to trust the process of designs they have been using for years, such as Excel, manual calculations or their company templates. In fact, they have implemented Revit solely for the purpose of producing construction drawings. They miss the point that Revit can be used for improving performance and collaboration, not only for the drawings to look correct on paper.

In reality, engineers use Revit in conjunction with other third-party software. However, this disconnects the Revit model and calculations, lowers the level of accuracy and results in multiple recalculations.

In fact, Energy analysis is easier to perform in Revit than in any other program. Using Revit for heating/cooling calculations ensures that any changes that were made in the architectural model will be reflected in energy calculations. If you plan on performing energy analysis in Revit, you must define Energy settings, as well as spaces/zones at the beginning of the modeling. To do so you must verify that all spaces are set up with space elements (shafts, plenums, sliver spaces), spaces are added to zones other than the default zone and building/space settings are customized for the project.

Energy analysis runs on an Autodesk Insight subscription. To use it, you must be signed into Revit with a subscription-enabled Autodesk account. To use Energy Optimization for Revit, ensure that the user interface option for Energy analysis and tools is enabled. If not, icons will be greyed out.

Using the Analyze tab > Energy > Optimization pane, you can define Energy Settings, Location, Generate Energy Model,  and Optimize Performance:

The 3 Main Types of Panel Schedule Templates in Revit

By Olena Kryzhanivska, AEC Technical Consultant at SolidCAD

Panel schedules are an essential part of any electrical design and provide a level of coordination that ensures accurate design and documentation.

Panel schedules can be created before or after circuits are connected to the panel. Once a Panel is placed in a model, a panel schedule is listed in the Project Browser. Using the Analyze >Panel Schedule tool, you can create Panel Schedules using a default template. You can create one or multiple Panel schedules from the Panel Schedule dialog. You can also simply select a Panel in a model and the Panel Schedule tool will become available for this Panel. Keep in mind, you will need to associate each Panel with a Distribution system. This parameter is available in Instant Properties under the Electrical-Circuiting group. The Distribution System is defined under the Manage tab > Electrical settings.

Revit provides 3 main types of panel schedule templates: Branch panelData panel and Switchboard.

On the Manage tab, select Panel Schedule Templates and click Edit a Template.

Are we beyond BIM?

If everybody is so proficient with the change to a BIM process, then why aren’t building projects embracing it more widely? Why aren’t those firms who have embraced it finding the efficiencies that it promises? Why are our buildings not being constructed with less problems? Most importantly, why are those people who build those buildings still not convinced that the move to BIM has improved the quality, capability, efficiency and functionality of their products?

BIM has been around for over 15 years and still many architectural firms are struggling with how to actually leverage its potential. Engineering firms are not utilizing the information in the data-rich models being created. Contractors are spending valuable time remodeling the digital information created by their design teams so that they can utilize them for their purposes. Finally, these models are not of much use to the owners and even more work needs to be done for them to get a true digital repository of the structures they have created.

What has gone wrong? Why can we not create a true digital model of a building that can be used for design; then passed onto production of construction documents; then passed onto the contractor him/herself to build and extract useful data from; and finally passed to the owner to utilize throughout the building’s life-cycle. Along the way, why isn’t this data-rich model used for a myriad of additional benefits? A true building information model should exist throughout the life of a building.

The answer is that WE CAN! The secret is that all of these participants have to want to work together to achieve a set of common goals. The only person who can define what these are is the person paying the participants; yet that person does not have the experience or knowledge to do what is necessary. Until we can get together as one team pulling for that elusive set of common goals, the building process and the resulting building will be a disparate set of activities producing a result that reflects that lack of cohesiveness.

It is time that we got together and came up with a better way to use BIM so that everybody in the process can benefit.

BIM 360 Design – the next gen of Collaboration for Revit

By Vicky Browne, Marketing at SolidCAD   

As of April 9, 2018, Collaboration for Revit is available as BIM 360 Design – Autodesk’s next-generation cloud work-sharing, data management, and design collaboration product.

This is part of several changes to the Autodesk BIM 360 portfolio of products.

Collaboration for Revit (C4R) background

Collaboration for Revit (better known as C4R) was one of the most successful products from Autodesk. It was a simple product, but it provided a service not available affordably through any other means.

Collaboration for Revit gave users on project teams, not in the same office, the ability to work together in one model. Prior to its release, Revit worked well within an office; not so well between offices. With the arrival of C4R, in one fell swoop, those barriers were eliminated.

What has changed?

BIM 360 Design is the next generation of Collaboration for Revit (C4R). It enables the cloud worksharing you’ve come to love in C4R but connected to the next generation BIM 360 platform.

With the new changes, everyone will have more seamless access, whether in BIM 360 Docs or Design (C4R) as they will both sit on the new Autodesk BIM 360 platform.

Revit 2019: Essentials for MEP Engineers

By Olena Kryzhanivska, AEC Technical Consultant at SolidCAD

Getting started with Revit can feel daunting. It’s an unfamiliar program that may not work like your current software. But, like anything new as you become more familiar with it you will start to see the benefits of the basic modifying tools – Copy, Move, Align, Offset, Mirror, Array – as well as the special tools it offers like Systems, Analyze, and Collaborate all within a 3D environment. Layers, often an irritation, don’t even need to be thought about in Revit. Revit will place every object in the correct layer. You do not need to switch Ortho on/off or change Snaps. Revit will show alignment lines, angles, snap points on the go.If you are just starting out in Revit, here is some basics that you should know:

Model
Revit creates a virtual 3D representation of the model with the established relationships between elements.You can create as many views as required by the project. Every view of the model is a live view of the parametric elements. If an element is moved in one view, the position of that element in all of the views is instantly updated. Therefore, changing the elements will change the model instantly and all changes will be reflected on each view and plot sheets.

Revit Family Guide – Master Revit Families in 10 Steps

By , AEC Technical Consultant at SolidCAD           

A Family is a group of objects that form a building component such as a door, a wall, a window or a chair. All families are associated to a specific category and contain a set of properties (parameters) and a graphical representation associated to these properties.

Understanding how to create and edit Revit Families is a must if you want to take your Revit skills to another level. Revit’s Family Editor has all the tools you need to create custom components for your Revit projects, and here you will learn 10 steps to master this environment.

#1 – Understand family types

There are different Family Types in Revit:

System families – Generally, assemblies (walls, roofs, floors, ceilings, etc). Our flexibility here is limited, we can create different types of system families, but we can’t add parameters to control their graphical representation.

Component families – Families we can create from scratch and load into the project. Can be extremely flexible and customized based on your needs. In this blog post, we are going to focus on them. They can be hosted, free standing or work plane-based.

In place families – ‘One-off’ families created inside the project environment that do not require geometrical flexibilization. Should be used with caution, as they can increase the size of the file and impact model performance.

#2 – Understand the use of parameters

Parameters are used to define and modify elements in Revit. They give flexibility to project components. By changing the parameters assigned to a family we can create different versions of the family, called types. Each family type has an identical set of parameters called “type parameters”.

When placing a family type in a project, you create an instance of that element. Each instance has a unique set of parameters called “instance parameters”. By changing these parameters, you can apply changes independent of the family type, that will only apply to that specific element in the project. Keep in mind that if you make any changes to the family type parameters, the changes apply to all element instances that you created based on that type.

It is up to the person creating the family to define its parameters, and to determine if a parameter is going to be applied to the type or to the instance level. The following pictures are a good example of that statement. These two doors are very similar graphically, but each one has different instance and type parameters – for example, one door has a parameter called “Door Material” and the other “Panel Material” with, essentially, the same function. Why? Probably just because they were created by two different Revit users.
