AftabRad Revit Add-in: Finding the Elements that are Heaviest When are Exported to Radiance and Try to Simplify Them.

When the model is exported to Radiance but receives a warning message (like the one in below) about the size of the exported model,

please follow the below steps to find which elements are heaviest when exported to Radiance.

1- When exporting the model to Radiance on the Revit2Radiance page, please check the Mat. Based Rad file checkbox.

Then press the Do Export2Radiance button.

2- Please wait until the process of creating different Radiance files connected to each material is finished.

3- Now, in the folder that all Radiance files are saved (you can use Open the Calculation Folder button on the Revit2Radiance page to open that folder, or use the Browse to Define the Exported Radiance File button to change the name of the main exported Radiance file and its folder),

There should be a folder named Separated_RAD_Files. Inside that folder, there should be a number of *.rad files named by each material that is used in the model.

By checking the size of those files, we can find which rad files are the heaviest and consequently which materials are used in the heaviest elements when exporting to Radiance.

4- After finding such materials are used in the heaviest elements, we should go to the AftabRad ClickToFindMaterial command.

5- Inside the Selecting Material Page, please select one of those materials, that are found in step 4, under the Revit Material Name Combobox.

6- Then by pressing the Isolate by Elements button, you can find which elements include that selected material.

When the elements are isolated, by using the buttons on the below page, you can see the isolated elements from different view angles

To back to the main Selecting Material Page, press the Close button on the Change View page.

7- To show all elements, press the Reset button that is placed next to the Isolate by Elements button.
