Revit 2019 – Slow performance when selecting the File Tab

A very quick tip for a very annoying issue. Sometimes, when you delete or move Revit models the recent files list still looks for these missing references. This has an impact when you click the File Tab (can take minutes!) to open.

A quick fix is to delete these file paths from the Revit.ini file. The Revit ini file can be found the following folder (replace your user name shown in red):

C:\Users\YourUserName\AppData\Roaming\Autodesk\Revit\Autodesk Revit 2019

Open the Revit.ini file in notepad and remove the recent files (shown with the Red box). Click the Save command and the Revit.ini file will be updated.

Restart Revit and the slow File Tab should be much quicker!

Revit 2019 Tutorial – Analytical Model Visualisation

Quite often when structural engineers are viewing the analytical model within Autodesk Revit it can be a little difficult to see which members are fixed or pinned or have specific release conditions set. The standard way to achieve this is to select the analytical bar and then look in the Properties Palette for the information.

The image shown below is a typical representation of the analytical model with the loads and end colours shown.

Here you can see the same model  with some filters applied to help visualise fixed and pinned conditions.

The filters are set within the Visibility/Graphic Overrides dialog box. In the example below, I have chosen to indicate a Fixed or Pinned condition by using the colours red and green. Note that I have also had to create a separate filter for columns.

In the image below, you can see the new OR functionality being used to set a filter that either has the start or end release set to Pinned.

I would suggest that you create a separate view within your current structural template to enable the engineers to easily check the release conditions on the analytical model, this is much easier that selecting each element and viewing the Properties.

Hope this Helps,

Revit 2019 Tutorial Part 1 – Adding Vertical Bracing Systems

I still find many people asking what the best methods are for adding bracing to steel models, some are still using beams to try and model bracing, others still get into a bit of a mess with vertical bracing, more struggle with the representation on drawings.

I thought it was about time I created a tutorial on this subject, covering both horizontal and vertical bracing as well as some typical connections for adding those all-important details.

So first we need to look at some of the basics. In the images below, you can see Vertical, Horizontal and Roof Bracing.

Revit Bracing Examples

Creating Vertical Bracing

When creating vertical bracing it is best to create a framing elevation. The framing elevation creates an elevation on the frame a few hundred millimetres deep and sets a working plane for the bracing.

Framing Elevation

You must use the dedicated brace command to efficiently add bracing.

Bracing

You can roughly sketch the bracing that you require and then use the Properties Palette to fine tune the exact location of the bracing.

In the example below, you can see some vertical X-bracing, note that the start and end attachments are attached to the correct levels and you also have the option of adding offsets from each of these levels.

Vertical Bracing with PropertiesIn this example we have used Equal Angle to create the bracing. Both angles are in the same plane and hence clash.

This can easily be resolved by using the y Offset Value on each member. The analytical line remains centred, but the physical elements will be located correctly.

Offset Bracing in the Y Axis

The bracing is automatically represented in a plan view and can be tagged. The standard in the UK is to show a parallel line on the outside for bracing above and a parallel line on the inside for bracing below.

Plan Bracing

You can control the type of representation and spacing in the Structural Settings dialog box.

Structural Settings Bracing

Finally, if you want to tidy up the bracing and make the drawings look a little better you can either use 2D detail components to represent a connection or use the connection tools to add 3D connections.

RC Detailing Tutorial – Revit 2019

In this short tutorial we will look at the reinforcement of a simple column and foundation. The reinforcement is modelled manually to show you how reinforcement bar is placed in elements. We then schedule the reinforcement to BS8666:2005 and produce a simple drawing.

COLUMN DETAIL

Here is the bending schedule shown below.

RC Bending Schedule

The tutorial is using the Excitech Revit RC template but everything else is standard Revit 2019.

Hope you enjoy the tutorial?

Revit 2019 – New Steel Features

Well, it’s that time of year again to review the new features of Revit, seems to come round so fast. As I did last year, I will review the steel and concrete features as separate blog posts and videos as we have a raft of new features to look at!

If you would like to jump directly to the steel video then here is the link.

New Steel Ribbon

Autodesk are further extending the Level of detail that can be presented by adding specific modelling tools to extend the power of structural connections and end treatments. You now have dedicated tools to create notches, saw cuts, holes and chamfers and rounds to steelwork. This allows for a greater Level of Detail when modelling and these features can be directly linked to Advance Steel for full Automatic fabrication documents.

Revit 2019 - Steel Detailing Ribbon

The use of these new tools will depend on the need for modelling to this level of detail. For example, bridges may require a greater Level of detail but a traditional steel frame modelled by an engineering consultant may not require any connection details, these will be added by the fabricator.

A particularly nice feature is the ability to use a standard connection and then break the connection into the fabrication elements such as plates, bolts, cuts etc. This allows for easy modifications to connections and the ability to create your own connections.

For a detailed look at each tool check out my video at the top of this post.
