FILTERING OUT THE NONSENSE ABOUT FILTERS

FILTERING OUT THE NONSENSE ABOUT FILTERS

In the last few posts, we’ve discussed view ranges and visibility graphics. It only makes sense that we expand on one of the most useful and often overlooked visibility options: filters. If used correctly, filters can help you easily identify certain elements in a sea of walls, floors, beams, etc.

You already know from a previous post where to access the filters dialogue. If you don’t, you should review our visibility graphics blog post or look in the visibility graphics dialogue box.

Let’s start with the simple steps to create a new filter.Copy Button (3)

  1. Open the filters dialogue.
  2. Click add
  3. Select new/edit on the right side of the box.
  4. Select the new option (the first icon under the list of current filters).
  5. Name it and then click OK.
  6. Once you’ve named your filter, you’ll choose the categories that will help define your filter.
    1. If you’d like to find all the CMU walls in your view, select walls.
    2. If you’d like to find all the concrete walls and floors, you would select floors and walls.
    3. The categories you select will determine the options you see in the Filter Rules section of the dialogue.
  7. Now you have a named filter and categories selected. Time to set the filter rules.
    1. The first drop-down menu allows you to select which parameter you’d like to filter.
      1. If you’re trying to filter CMU walls, you’d select Type Name.
    2. The second drop-down menu is where you pick the filter operator.
      1. If you’re trying to filter CMU walls, you’d select equals.
    3. The third option is where you pick the filter value.
      1. Since our current example is about filtering a type of wall, you can choose from a drop-down menu. Some filter parameters will mean that you need to put in a value instead of choosing from a drop-down menu.
    4. Click “OK” and celebrate! You’ve just created a filter.

You didn’t think you were done, did you? Now you have to apply your filter to your view.

When you click OK, you’ll go back a dialogue box and be able to select the filter you just created and then click OK again. You have a few more options to adjust your filter before exiting the main filter dialogue. The visibility option is first. Say you want to hide all of your CMU walls. Make sure the box is unchecked and they’ll all disappear from your view. If you’d like to color code them, adjust the Projection/Surface and/or Cut properties. You could make them all solid blue or pink dots. Lastly, you can just make the element(s) halftone if you’d like to subdue the visual appearance.

Filters are useful for so many reasons. Our CMU wall example is just one peek into how they can be used. Keep in mind that the first filter in the list is going to get the highest priority in Revit. For example, maybe you wanted to filter all beams that were 10’ long and then of the beams that were 10’ long, you wanted to know which were Wide Flanges. You could do this in one filter or if you’d prefer to keep them separate, you could make sure your 10’ beam filter is first in the list and then the Wide Flange filter is next.

You can also create filters based on selection sets. Selection sets can be managed from the Manage tab. Imagine that. You can save a set, name a set and then load the selected set of elements that you need to manipulate.  This tool is rarely used but can be incredibly useful.

Now, that’s a long but basic (and hopefully helpful) explanation of how to create filters. If you’ve never used a filter before, I highly suggest you pop into the visibility graphics dialogue and give it a go.
