When the BVN/Jasmax team reviewed the design of an inventive sunshade for a large New Zealand office building, the team response to Melanie Tristram, Jasmax Associate - Revit Manager was, "We have no idea how we are going to construct this in Revit. It is going to take so, so long."

Angular blades would make up the diamond-shaped panels. Blades of varying length and color were both perforated and non-perforated. Additionally, a rotation factor would be included as well. With dozens of individual possibilities for permutation with each single blade, the goal was to have "no double-ups." The tally of possible permutations devoid of any repetition: about 3.5 million.

BVN with Jasmax had already engaged in a much smaller scale project with some similar properties. In the firm's quest for a solution, they had made online queries with Ideate Software and, seeing the possibilities contained within Ideate BIMLink, they had downloaded the trial version.

After experiencing success with the limited Ideate BIMLink trial and further consultation with Ideate Director of Software Development, Glynnis Patterson, Jasmax became one of the early adopters of stand-alone Ideate BIMLink.

End result - It took minutes instead of days.

Tristram says of the use case, "The time savings represents more than the hours we did not have to spend. No one, certainly not our Revit users, wants their valuable time caught up in days of data entry. That process is unsatisfying and it is open to error. Ideate BIMLink improved our efficiency and accuracy." Ideate BIMLink allowed the team to harness the data on each individual blade and visualize how it would or could interact with every other one. On each and every occasion that they wanted to explore a potential set of interactions, without BIMLink, they would have spent a day and a half of tedium. With BIMLink, they achieved each exploration in about half an hour.

Plamen Hristov, the Director of Design Technology at Capital Engineering Consultants, has aggressively pursued mastering the Revit MEP data model. Below is a transcript from a recent chat between Plamen and Director of Ideate Software, Glynnis Patterson on the topic of a solution for editing specified power and lighting loads in Revit using Ideate BIMLink.

GP: Plamen, you called Ideate Software technical support recently asking if it would be possible to edit the Specified Power and Specified Lighting properties via Ideate BIMLink. Can you give us some background on why these fields are important to your work?

PH: At Capital Engineering we are always looking for ways to automate tedious tasks and processes as well as push the boundaries of Building Information Modeling. In this case we wanted to extract as much data as possible from a large healthcare facility Revit model and use it as a starting point for our load calculations in Trane Trace. The project has over 1000 spaces and usually doing the takeoffs and recreating such model in Trane Trace can take several days. Once the data is extracted and processed in Trane Trace and Excel, we wanted to populate the Revit model with it.

GP: Is this kind of task unique to that project type?

PH: No, it is not. Load calculations are an essential part of designing the mechanical systems and they are performed for every project.


Editing Space with Ideate BIMLink

GP: Initially these values were displaying as read-only properties in Ideate BIMLink but as you pointed out to us, it's easy to globally select the spaces and allow these values to be specified. Once that step is taken Ideate BIMLink can easily edit these properties as shown in the image above. Thanks for taking the time to share your expertise with us Plamen!

Long before I knew anything about Ideate BIMLink, I found myself spending a lot of time creating and managing Revit data, especially for custom building facades. While massing and adaptive components give you virtually limitless possibilities when it comes to design, using a simple curtain wall with custom panels can be just as effective. But what would happen if you have a lot of curtain wall panels that you want to randomize, such as their thicknesses and materials? Having to manage this data, panel by panel, could take you several days and leave you very frustrated, especially if you have hundreds of panels to edit.

Using Ideate BIMLink, I will show you how you can easily get started with Computational Design by exporting your curtain wall panel data to an Excel file and quickly apply random materials and thicknesses to several hundred curtain wall panels in a matter of seconds for a unique and fun building façade.


In this example, we will be using Ideate BIMlink to manipulate over 700 curtain wall
panels to create some colorful glass boxes with a variety of block depths.
 

Here's how you get it done. Step 1: Create a custom curtain wall panel starting with the Curtain Wall Panel.rft template file that ships with Revit.


Create a custom curtain wall panel, with custom parameters.

Step 2: Create a Material Parameter and set its properties to Instance.

Step 3: Create a Thickness Parameter and set its properties to Instance. Setting both the material and thickness parameters as instances will allow for greater flexibility of the family and will make the randomization of the panels thickness and materials a lot easier to control.

Step 4: Assign the custom material parameter to the default Material Parameter that is part of the Curtain Wall Panel template.


Assign the custom material parameter to the Default
Material parameter in the Curtain Wall family file.

Step 5: Save the Curtain Wall Panel and load it into your project. Once the curtain wall panel is loaded, it will be available so that you can create a custom curtain wall and apply this panel to that wall.

Step 6: Create your curtain walls using the custom Curtain Wall Panel family and a pattern of your choice.


Create a custom curtain wall using the custom curtain wall panel.

Step 7: Create a link file in BIMLink using the Curtain Wall Panels category. You can use a pre-defined .link file and edit the fields as necessary, or create your own from scratch.


Create an Ideate BIMLink link by adding the required fields for modification in Excel.

Step 8: If your project has multiple curtain wall panel types, it may be a good idea to filter out the ones that you are not interested in editing. In this example, I set my filter to only show my custom panel.


Filter out unwanted Curtain Wall Panels in your link definition by selecting the
custom Curtain Wall Panel that you created.

Step 9: Once your Excel file has been exported and opened, you will need to add a tab next to the Excel tab that was exported by Ideate BIMLink so that you can define the Material List that you want to apply to the custom curtain wall.


Create a new tab for your Materials, then create a Named List for those materials.

Step 10: Select all of the materials and then give the selection a name. In this example, I called this list MaterialList. We will use this list to create an index of materials so that Excel can randomize the materials on the Excel spreadsheet that was exported with BIMLink. Take note that we have a list with 7 materials. This number will be very important when we randomize the materials.

Step 11: In order to randomize the materials for the Curtain Wall Panels, you must use the INDEX formula. What the INDEX formula does is it returns a value or the reference to a value from within a table or range. In this example, we are indexing the MaterialsList and randomizing the list as well. Below is how the formula for the Material Parameter works:

  • INDEX(array,row_num,column_num), where the array is the MaterialList, the row_num is the row number from the MaterialList and the column_num is the column number from the MaterialList.
  • ROUND(Number, num_digits), where number is a specified number and num_digits is now many digits you want to round by. In this example, we are going to ROUND a random number.
  • RAND(), which will return a random number greater than or equal to 0 and less than 1.


Randomize your Material List by indexing the list and applying the randomization formula. 

For this example, we randomized the row_num by using the RAND() feature, then ROUND the randomly returned value (anything between 0 & 1), then multiplied by 6, with 0 decimal places, then adding 1 (which represents the 7 rows from the MaterialList), and finally, referring to Column 1 of the defined MaterialList. The final results is a completely randomized list of the 7 materials that we created.

Step 12: In order to randomize the Panel Thickness Parameter, you can use the RANDBETWEEN () formula. What this formula allows you to do is specify a lower and upper value and then a randomization will occur between the lower and upper values. Below is how the formula for the Panel Thickness works:

  • RANDBETWEEN(bottom, top), returns a random number between a bottom and top value specificed.
  • &(text1, text2, etc) [Also known as the CONCATENATE formula], allows you to join several pieces of text together.


Randomize the Curtain Wall Panel thickness by applying the RANDBETWEEN
formula and adding the inches symbol to the outputted number.

For this example, we randomized numbers between 1 & 48, then added the inch marks to those numbers using the & or CONCATENATE feature. This will return all of the randomized values in inches, which is easy for us to understand.

Step 13: Once you have completed the randomization of the Material column and the Panel Thickness column, you can either accept the current values and import the Excel back into BIMLink or you can re-randomize the values for both columns. To do so, simply hit the F9 button on your keyboard as many times as you like.

Step 14: Once you have saved your Excel file and imported it back in using Ideate BIMLink, be sure to review the dialogue box for errors and warnings, along with all of your changes. If everything looks good, click on the Import button to finalize your changes.


Review imported Excel file for errors, warnings & changes to original parameter settings.

Enjoy the results!

Ideate BIMLink can help expedite and ease the creation of Space Analysis Diagrams. Programming has to convey data in a way that is clearly understandable in tabular format and diagrammatic plans. Programming diagrams developed under this phase are typically divorced from the data source. Transposing this data into Revit objects typically involves the tedious task of manually retyping the information into Revit Schedules. Now, this can be streamlined by importing the program data directly from Excel into Revit, using Ideate BIMLink, the Revit add-on that imports Excel generated data into Revit.

To demonstrate this workflow, I will use as an example the overall program data of two fictional institutional buildings. I will show how you can connect the information of Revit Area objects with the Program spreadsheets. Then, we will build Space Diagrams with Areas and Area Boundary lines.

Step 1: Build the Area Parameters in Revit:  A solid understanding of the programming data will help you decide how to build the parameters. Area parameters are typically Instance parameters because each area displays different property values. Decide what fields need to be tagged and build those as shared parameters. In the example below, I created five custom parameters, including two Shared Parameters called 'Programmable Area' and 'Neighborhood' that will be used as labels in tags.

Step 2: Build New Area Plan Schemes for Programming Options:  Customize your Area Plan views by adding them under the Area and Volume Computations. You are not limited to the Gross and Rentable Schemes that come out of the box in Revit. You can use Area Schemes to manage your Area Plan options, Zoning Requirements, Buildings, Occupancies, etc.

Step 3: Build an Area Schedule in Revit and Add Area Placeholders:  Add into the Schedule of Areas as many rows as needed to develop your space analysis diagram.  The idea is to create placeholders for each of the required spaces. There is no need to spend time filling out the parameter values because we will do this more efficiently in Excel.

Step 4: Export the Data to Excel:  Using Ideate BIMlink, export the parameters to Excel. BIMLink ships with a 'Link' definition with a preloaded set of parameters of the Area Category. Unlike Revit Schedules, the link is inclusive of all the systems and user created Area Schemes, enabling users to manipulate the data of multiple Area Plans in a single database. Add any additional custom parameters in the Area link as needed, and/or exclude the ones you don't need.

Step 5: Fill the Area Information in Excel:  Populate the Area parameters using the extended capabilities of Excel. There are many different ways in Excel to do this, to name a few:

  • Create external references between the cells of the Link and the Programming report (=[FileName.xls]Worksheet!Range). In this scenario, the two database files will be linked, and the BIMLink link would remain updated.
  • 'Nest' the programming data into a new tab and connect the cells between tabs (=Worksheet!Range).
  • Copy/Paste the data.

The choices you have to edit, sort, and modify the parameter values in Excel are far superior than the out of the box Revit ones.

Step 6: Use Pivot Tables and Charts in Custom Tabs:  The beauty of having the data in Excel is that you can use all the available Excel tools to present the data in a way that is meaningful to the client, like Pivot Tables. Build Pivot Tables in Excel to automatically sort, count and summarize the program in the same BIMLink worksheet as long as they are placed in a different tab. Data in the custom tabs will be preserved even if the link is re-exported. Keep the original 'link' tab away from format modifications; this will ensure a seamless import/export process. Another feature in Excel you can use is to assign background colors to different cell values using the Rules under Excel Conditional Formatting


Format Cell Fill Color Using Rules in the Excel Conditional Formatting

Here are few other examples of how the programming data can be displayed using different Pivot Tables, in the same BIMLink file:

Step 7: Re-Import the Link Data Into Revit Using Ideate BIMLink:  All the Area parameter values will be updated. Again, BIMLink will only read the data in the original tab when re-importing.

Step 8: Build the Space Needs Diagram Using Area Boundary Lines and the Area Placeholders:  Since all the areas live in the project as placeholders in the schedule, pick the appropriate Area from the Options Bar. I applied Color Schemes to the view, based on the Name value, but we can also build others based on the information contained by the Area objects, like Zone Type, or Area Ranges. These color Schemes can also be pre-built into your View Templates.

Parameters, Shared Parameters, Programming, Pivot Table, Chart, Area, Boundary Lines, Revit, Revit Parameters, Revit Space Needs, Space Needs Diagram, Ideate Software, Ideate BIMLink, BIMLink, BIM, Excel to Revit
Space Need Diagram Sample

The BIMLink 'link' may need to be re-exported and re-imported to reflect changes in the space program. By managing the data in Excel and importing into Revit, Ideate BIMLink expedites the process of creating space planning deliverables. The same process is useful in producing other kinds of deliverables such as: Mixed Use Code Analysis, Fireproofing Diagrams, Landscape plans, Master Plans, etc. If you are interested in receiving a copy of these Pivot Table excel samples, drop us a note to support@ideatesoftware.com.
