Introduction
Line styles in Revit play a critical role in defining the appearance of lines in your projects, influencing both the readability and professionalism of your drawings. However, manually adding or updating line styles can be a cumbersome and time-consuming task. This article explores how to use Dynamo in conjunction with Excel to efficiently add Revit line styles in bulk, automating and simplifying this process.
Importance of Line Styles
Line styles are essential for:
Differentiating between various elements and categories
Maintaining uniformity and clarity in project documentation
Ensuring adherence to project standards Proper line styles improve the overall quality and readability of your Revit drawings, making them easier to interpret and work with.
Challenges in Adding Line Styles
Manually adding or updating line styles in Revit can be challenging due to:
The repetitive nature of the task
The potential for human error
The complexity of navigating through Revit's settings These challenges often lead to inefficiencies and inconsistencies, which can undermine the quality of the final output.
Introducing Dynamo and Excel
Dynamo is a powerful visual programming tool for Revit, enabling users to create scripts that automate tasks. By integrating Dynamo with Excel, users can leverage the power of spreadsheet data to streamline the addition of line styles in Revit.
Common Use Cases
Setting Up Initial Line Styles
When starting a new project, the script can be used to quickly set up all necessary line styles, saving time and effort.
Making Bulk Updates
For ongoing projects, the script allows for bulk updates to line styles, ensuring that changes are applied uniformly and consistently.
Ensuring Consistency Across Projects
By using the script, firms can ensure that all projects adhere to the same line style standards, maintaining consistency and professionalism.
Example Use Cases
Example: Adding Line Styles for a New Project
For a new project, you can prepare an Excel file with the desired line styles and their properties. The Dynamo script will read this data and automatically add the line styles to the project.
Example: Updating Line Styles in Existing Projects
For existing projects, the script can be used to update or add new line styles based on updated standards or requirements.
Example: Standardizing Line Styles Across Multiple Projects
The script can also be used to standardize line styles across multiple projects, ensuring consistency and compliance with firm-wide standards.
Benefits of Using Dynamo with Excel
Streamlined Workflow
Using Dynamo with Excel simplifies the process of adding line styles, allowing for bulk changes to be made quickly and efficiently.
Automation of Repetitive Tasks
Automating the task of adding line styles reduces the risk of errors and frees up time for more critical project activities.
Improved Accuracy and Consistency
The integration ensures that changes are applied uniformly across all models, maintaining consistency and precision in your drawings.
Setting Up the Environment
Required Tools and Software
To get started, you will need:
Revit (compatible with Dynamo)
Dynamo (installed and configured within Revit)
Microsoft Excel (to prepare and manage line style data)
Installing Dynamo, Dynamo Packages and Configuring Excel
Ensure that Dynamo is installed and properly configured within your Revit environment. Prepare your Excel spreadsheet with the line style data, including columns for line style names, colors, and weights.
The only package you need for this script is bimorphNodes. I used version 5.1.3
Creating the Dynamo Script
You can create this yourself, or just download the script at the bottom of the page.
Script Workflow Logic
Import Excel File & Read Sheet: the excel file has to be formatted properly for this script to work the way it was intended.
Parse excel data by content type and assign to lists with variables: take the excel data and combine the like types to create lists that we can use for import. All the line names, weights, colors and patterns will be assembled to their own list but hold their same index value so they can be assimilated at the end of the script
Translate the excel color and line pattern from text strings to actual Revit elements: The text values in the name and the integer values in the line weight projects can remain exactly how they are because that's what the end node expects. The other two values, color and pattern, need to be translated into something Revit understands. So we assign the lists to variables and make 'if' statements that translate the data into something Revit can understand.
Convert old line styles to new ones: use pyRevit to convert existing line styles to the newly create line styles if necessary.
if statement example spelled out: if an item in the list contains the value "DASH 1X" assign it to the Line Pattern Revit element that was put into the DASH1X variable.
Detailed Walkthrough
Importing Data from Excel
Importing data from Excel involves:
Setting up the Excel file with the required data in the required format
Using Dynamo's Data.ImportExcel node to read the data
Parsing the data into a format that Dynamo can work with
null is translated to be a solid line.
halftone is translated to be grey
Parse Data into Like-Types
Parsing Data involves:
Getting the excel data, but not the headers
Transposing the list to combine the data into lists (getting all the names in one list, the weights in one list, etc)
Then the lists are separated and we can extract them based on their index values
Mapping Excel Data to Revit Line Styles
Mapping data involves:
Identifying the relevant nodes in Dynamo for Revit line styles - patterns and colors
Connecting the imported data to these nodes by assigning the list and the dynamo nodes to variables
Iterate the list through if statements to assign the excel data to the dynamo data
customize the inputs and variables to align with the colors and patterns you need
Line Patterns:
// match excel data to revit elements
DASH1X;
DASH2X;
DASHDASH2X;
DASHDASH4X;
// list of line patterns above;
list;
inputLinePattern = list;
// Choose the variable based on input name using if statements
// Variable in quotes comes from exvel file.
// Variable after comes from input above
output = inputLinePattern == "DASH 1X" ? DASH1X :
inputLinePattern == "DASH 2X" ? DASH2X :
inputLinePattern == "DASH DASH 2X" ? DASHDASH2X :
inputLinePattern == "DASH DASH 4X" ? DASHDASH4X :
inputLinePattern == "null" ? null : null;
// default to null if none match. null = solid line pattern;
output;
Line Colors:
// convert excel color text to revit elements
red;
blue;
black;
grey;
green;
// list all colors above
list;
inputColor = list;
// Choose the variable based on input color using if statements
output = inputColor == "red" ? red :
inputColor == "blue" ? blue :
inputColor == "black" ? black :
inputColor == "green" ? green :
inputColor == "halftone" ? grey : black;
// default to black if none match;
output;
Convert Old Line Styles to New Line Styles:
If you have existing line styles that you want to migrate into the new line styles, use pyRevit to convert line types!
