There is a great video on View Range by Paul Aubin at the link below here: http://www.screencast.com/t/eCJaIgaevE
It is very well explained and I learned some things I had no idea about, like the ‘tolerances’ associated with various elements when using View Range. After using Revit for so long, I’m surprised this piece of important information had ‘slipped through’! I did some searching, and these tolerances are listed in the Revit online help at this link and hinted at in the support information here.
For your convenience, I have copied the information from the Revit help page below:
Additional View Range Rules
- Model elements located outside of the view range generally are not shown in the view. The exceptions are floors, stairs, ramps, and components that stay or are mounted on the floor (like furniture). These are shown even when slightly below the view range. In addition, fascia, gutters, and edge slabs are shown when their bottoms are within a tolerance of the primary view range bottom.
Floors located outside the view range use an adjusted range that is 4 feet (approximately 1.22 meters) below the bottom of the primary range. Floors are drawn with the Beyond line style if the floor exists within this adjusted range.
- Elements that are strictly below the cut plane, but are at least partially within the view range, are shown as viewed from above. Components display according to Family Element Visibility Settings for Plan/RCP. See Managing Family Visibility and Detail Level
- Walls shorter than 6 feet (approximately 1.83 meters) are not cut, even if they intersect the cut plane.
The 6 feet are measured from the top of the bounding box to the bottom of the primary view range. For example, if you create a wall with a sloped top face, when the top of the wall is 6 feet away from the bottom of the primary view range, the wall is cut at the cut plane. When the top of the wall is less than 6 feet, the entire wall shows as projection even where it intersects the cut plane. This behavior always occurs when the Top Constraint property for the wall is specified as Unconnected.
- There are a few categories for which an element located above the cut plane but partially below the top clip is shown in plan. These categories include windows, casework, and generic model. These objects are shown as viewed from above.
- Visibility in RCP views is similar to plan views with the exception that objects are presented as viewed from below and mirrored.

I received the information about the screencast from Fear and Loathing in a CAD vs BIM World at http://cad-vs-bim.blogspot.com/2009/12/view-ranges-explained.html
We were given the ‘Slanted Column’ ability when some of the Structural tools were recently incorporated into Revit Architecture. If you have been pulling your hair out trying to place one of these slanted columns in a Plan view (where the tool is greyed out), the answer is simple. Go to a Section, Elevation or 3D View to place them!
You will likely need to set an appropriate workplane to ‘draw’ these slanted columns on.
The Brace tool is also quite cool – have a go at the ‘3D snapping’ capability in the Options bar (try it in a 3D view, obviously).

Revit is a very acceptable OOTB (out of the box) tool. If you are using Revit OOTB, there are really only two variables that determine your productivity. Assuming you have zero customised content, these variables are:
- your own skill and ability
- the performance of your computer
We are all working to try and keep our skills on the cutting edge. But is your hardware keeping up its end of the bargain? Our company made a significant investment into some middle to top-of-the-line workstations a few months ago, for which I am very grateful. If you are looking to purchase a new system, or upgrade an existing one, you should definitely review the
Model Performance Technical Note (you may have accessed this via Subscription, but this is a direct link to the PDF).

Revit makes it very easy to produce a LOT of drawings. This can result in a large deliverable. In one recent case, our Tender Issue of drawings consisted of 132 A1 sheets. Using CutePDF (with a couple of handy tweaks), we printed these to a PDF file of around 48 MB.
Depending on your email size policy, a file of this size would take anywhere from 5 to 16 emails to transmit.
To avoid this eventuality, I have explored various options for uploading large files and making them available to our colleagues. FTP seemed to be the answer, but one of our Clients is behind a proxy or firewall system that doesn’t allow FTP access – even with an anonymous account! So it was back to the drawing board…
Therefore, I decided to setup a HTTP server for file access. I downloaded Apache 2.2 (for Windows, without SSL). I took the following steps:
- Allowed a port through our firewall and directed it to the PC running Apache. We have a static IP, so I could now access Apache by typing in xxx.xxx.xxx.xxx:portnumber.
- Ensured that the opened port setting matched the Apache port in the httpd.conf file
- Disabled the ‘Indexes’ feature for a subfolder of the Apache ‘root’ folder (in my case this was C:Program FilesApache Software FoundationApache2.2htdocsFILES).
- Created a password for this folder using htpasswd.exe
- Enabled password access to the same folder using the following text in httpd.conf
AuthName “Restricted Files”
# (Following line optional)
# AuthBasicProvider file
AuthUserFile “C:/Program Files/Apache Software Foundation/Apache2.2/password/.htpasswd”
Now I can login to the PC running Apache, copy any file I want to serve via HTTP to the password protected folder, and then send a link to any of our colleagues that I want to gain access to this file.I also setup Filezilla FTP Server on another PC in our network, and forwarded port 21 through our router to this PC. I setup a user for a folder on this PC, and disabled all rights apart from ‘read’.I can now send an email that contains two hyperlinks to any large file we wish to transmit, one for FTP and one for HTTP. Both of these links are password protected.And all of this is done using free, open source software!
In the interest of collaboration, I have started a thread for BIM Standards and BIM Example Drawings Sharing at http://forums.augi.com/showthread.php?t=111047
If you need FTP access to upload data you would like to share, please contact me and I will make this available to you.
No doubt you would agree that our ‘attitude’ can have a big effect on our lives. If we look at things with the right outlook and viewpoint, we are more likely to feel successful and satisfied. So how does this relate to Revit?
There are a number of ways to approach Revit as a software platform. Consider some examples:
- “Revit is a modeling tool, and I want it to be able to easily model any form I can conceive.”
- “Revit is a drafting tool, and I want it to be able to draft quickly and easily, and I demand absolute graphic control over every single visible 2D element.”
- “I believe Revit should be intuitive and easy to use. It should be able to guess what I want and deliver the result that I seek.”
- “I have to use Revit because it is becoming the industry standard. I don’t have to like it or understand how it works.“
- “I want to understand What Revit Wants, so that I can use it in a productive and appropriate manner.”
I would say that the first 3 are basically impossible, for any software tool. However, in some ways Revit can deliver the results that you seek when approaching it with the attitudes of 1, 2, or 3. It is capable of many things, but it does have limitations. Attitude Number 4 is a problem though. Why? Because you MUST understand, at least to some degree, how Revit works. Otherwise you will never succeed, and you will face a lot of frustration.
Yes, you must grasp What Revit Wants. You must try to think in the same way that Revit thinks.
- Why is it trying to join the walls this way?
- Why is object A masking object B?
- What is causing Revit to show this line dashed instead of solid?
Instead of getting frustrated and angry, and instead of uttering unrepeatable phrases directed at ‘Autodesk’, just try and understand WHY. It is a little bit like meeting someone you don’t know for the first time. You may choose to judge them from first impressions. Or you may try to understand them, and why they act the way they do. If you come to understand them, you may be able to have a rewarding relationship with that person.In conclusion, give Revit a chance. Try to understand. Try not to judge or lose your patience. Don’t be afraid to find out What Revit Wants.

If you are having problems with the ‘Copy Spreadsheet’ utility, it is likely because you are running 64 bit Revit or you have recently updated Revit. If you haven’t heard of this tool, it is a simple program made in Autohotkey, and it automates the ‘copying’ of data from a spreadsheet into a Revit schedule. The Revit schedule will need to be a key schedule, and you will need to add the columns and rows before starting the utility.
