Revision Date on Drawinglist

Revit won´t let us add the current revision date to the drawing list, and since almost all my clients wants the information on the drawing list, I came up with this simple workaround.

1. Don´t use the Date field in the "Sheet Issues/Revisions" dialog, instead type the date just in front of the description.
2. Make a drawing list that displays the "Current Revision Description" field
3. Change the titleblock revision schedule to display only "Revision Number" and "Revision Description" (delete the "Revision Date" field), and add some line work, to seperate the "Date" from the "Description"

Autodesk really needs to fix this - i´m sure they intended to add this feature in version 2010, when they added the "Current Revision" and "Current Revision Description" to the drawing list fiels anyway.......

Simple, but get´s the job done :-)

Controlling user inputs in families

When building Revit families, and wanting to avoid nightmares, it may be useful to be in control of the user inputs. It could be a door that can´t be made if it´s more than 1200 mm´s (4´-0") wide.

Now, there´s a couple of ways to aproach this, but only one of them will actually tell the user that the input is not acceptable, I tend to combine two methods - 1. Warning & 2. Control

Warning Method

For this we need a custom parameter (yes/no) called "Width Warning", with a formula like this

not(Width < 1200 mm)

Now, create some model text, with a warning to the user - choose element properties for the model text, and aply the "Width Warning" parameter under "Graphics > Visible"

Now, if a user inputs 1200 mm´s or more as the width, the model text will show, and tell the user to correct the problem.

Control Method

It´s also possible to control the input, just in case that the user chooses to ignore the warning.

Create a new length parameter called "Controlled Width" and ad a formula like this:

if(Width > 1200 mm, 1200 mm, Width)

Now change the label for the current width dimension, to the new "Controlled Width" parameter.

Now the user get´s  a warning, and the door keeps a max. width of 1200 mm´s, even if the user input is greater than 1200 mm´s.

Quick printing of all sheets in a project.

As a freelance Revit Consultant, I run into many undocumentet nightmares with Revit - One of them is described below:

The print dialog in Revit, is missing some MAJOR features, like beeing able to print by "Sheet Size" - Here in Denmark, architects usually puts the various drawings on many different sheet sizes,which makes printing entire projects a truly nightmare.

On request of a client of mine, I finally contacted the "Factory", and togheter we came up with the following solution:

1. Forget about the fu***** print dialog in Revit - It´s useless.
2. So instead, go to one of the sheets in your project.
3. Choose Export > DWF:
4. Choose "Sheets in the Model" > "Select all"
5. Choose "DWF Properties" > "Print Setup"
6. Choose "Use Sheet Size" for the paper size
7. Click "OK" > "Export" and save your DWF file to the hard drive

8. And now, to the "UNDOCUMENTET" part > Double-click on the printer's icon in the Control Panel or select Settings in the Start menu and then choose the Printers option. > In the Printers window, select Server Properties from the File menu.

Now create new forms for your custom paper sizes - this will affect all installed printers.

If  you´re going to print to PDF, there´s another "WEIRD AND UNDOCUMENTET" part.

REPEAT the custom form creation part, but di it IN REVERSE - so that you enter the width as the height, and the height as the width. - Don´t ask me WHY !! But it´s the only way to get a PDF printer to pick up the custom sizes automaticly (Have tested with Adobe PDF, and Cute PDF)

My thanks go to Luciane Conceicao from the "Factory", who came up with the reversing part !

8. Open the saved DWF file in Autodesk Design Review, and then Print the entire sheets to your Plotter and/or PDF Writer - Remember to check "Choose paper source by DWF print" > Set scale to "100%" and "Center on paper"
This may seem like a lot of steps, but once the custom paper sizes / forms are created, it really takes no time to print entire projects, even with different sheet sizes.

BTW - Sorry about the missing screen captures from the print server properties (My OS is in Danish, so it would not make any sence to most people anyway)

It´s my goal to be posting more of these undocumentet NIGHTMARES, but this is it for now.
