Three Ways to go from Grasshopper to Revit

Luke Johnson

It seems that more and more people are trying to move intelligent data from Grasshopper to Revit.  There are at least 3 different ways to do this:

Have you tried all three?  Which worked best for you?

A recent and very informative post from LMNts describes their experience in moving data from Grasshopper to Revit.  Here is just one paragraph:
Chameleon appeared a few months ago and has proven to be an effective tool for adaptive components. The interface is intuitive on both the GH and Revit sides and we are yet to find any serious bugs with it. Another recent plugin is named Hummingbird (keep track of all these animals), a similar program which accesses the WhiteFeet Modeler to import adaptive components as well as Revit primitives (this has a lot of potential and will be discussed more in a future post). Take your pick, these are both great plugins.

Using the Anchor with EQ dimensions

Luke Johnson

In a multi-segmented, equality constrained dimension, you can use the anchor symbol to designate the anchored element. The element that is anchored remains stationary while you move other elements in a dimension.  

  • Click and hold the anchor symbol. A witness line appears for the anchor.
  • Drag the anchor symbol to the element you want to anchor.
  • Move any of the unanchored elements referenced in the dimension.
  • The element accompanied by the anchor does not move.

Anchoring Elements Referenced in Multi-Segmented Dimensions – WikiHelp

Also refer to my previous post:
What does the Revit equality dimension anchor do?

Using Autodesk Cloud as an auto-Syncing online file store

Luke Johnson

Did you know that you have an offline copy of your Autodesk 360 Cloud data?  It lives here:
C:UsersUSERNAMEAppDataLocalAutodeskAutodesk SyncCloudCLOUDUSERNAME

If you put a file in this folder, it will automatically get Synced to your online 360 account.  It doesn’t seem to matter what the filetype is – it uploaded my something.whatever file quite happily.

I assume there is a system setting somewhere that sets the sync interval.

In any case, you could make a shortcut to this folder on your Desktop and use it as online file storage, if you so desire…

Harvesting Hatch Patterns from Revit to PAT files

Luke Johnson

You have a Revit file with some custom hatch patterns (filled regions / fill patterns) in it.  You want to turn them into PAT files for re-use in AutoCAD or some other drafting program.  Here’s how:

  1. Make a Drafting View in Revit with a couple of Filled Regions in it.  
  2. Set the filled Regions to the Revit Hatch Patterns that you want to export to PAT files.
  3. Export the Drafting View to a 2000 version DWG file
  4. Open the DWG file in AutoCAD
  5. In AutoCAD, APPLOAD then browse to getpat.lsp file.  To get this file, right-click and Save Target as from this link.
  6. After loading the lisp file, File – Save As the DWG, to something in the same directory (this step just makes AutoCAD and the LISP aware of where the PAT files should be saved)
  7. Then, type GETPAT
  8. Select the hatch you want to export.  It *should* be saved as a PAT file to the same directory that the DWG file is in.

EDIT – you could also try this method:
What Revit Wants: Native Revit can make PAT files too – you just have find them …

Using Listening Dimensions with Angles

Luke Johnson

Listening dimensions is the technical term for the little blue dimensions that appear as you start drawing a line in Revit.  The bold entry is the one that Revit is ‘listening’ to the keyboard for.  When it comes to angular dimensions, if you start drawing a line then hit TAB it basically ignores the Angular snap increments and shows you the exact angle at your cursor position (go Manage – Snaps to see the increments).  Also, if you put an increment in the Angular dimension snap increments that is not divisible into 360, Revit will basically ignore it.

Holding Shift will constrain you to either vertical or horizontal directions.

In AutoCAD, you can access either the angle or the length of a line when creating a new line.  Sadly, Revit does not allow you to access the angle while creating a new line or wall – you can only enter a Length (as this is the bold listening dimension at creation time).

Basically, then, we need to consider some workflows for allowing angular entry.  Most of these are time consuming (see below).

Workflows:
Option 1 –

  1. Have a Drafting View open, with a line in it
  2. Select the line
  3. Adjust the angle
  4. Copy / paste into your current working view

Option 2 –

  1. Select a Plan View crop region
  2. Rotate it to the specific angle that you want to work with
  3. Start drawing a line
  4. Use SHIFT to contrain the movement (Revit respects the view crop boundary as defining the vertical and horizontal directions)

Option 3 –

  1. Draw line
  2. Select line
  3. Use angle dimension box

Option 4 –

  1. Draw line
  2. Select line
  3. Trigger rotate command

Do you have a better solution for angular entry at element creation time?  It wouldn’t be hard to come up with a better way than those described above.

Here is some more information I found while exploring this issue …

Unit entry:
=45d1 results in 450mm?  Why?

Great thread:
the value typed goes into the “listening” temporary dimension (which is the one that is bold).

Wikihelp:
If there is no linear dimension, you can enter an angular dimension, if applicable.

Line drawing tip – Radius between straight lines:
select Radius and specify a value.
A radius creates fillets at the specified radius between line segments, allowing you to create a rounded chain of lines. A line must be joined to the end of another line for a fillet to display. If a line is connected to more than one line, a fillet cannot be created.
The following image shows line segments sketched without Radius selected and line segments sketched with Radius selected.
