Revit Tutorial: Using Show Remove Hidden Lines Tool for Displaying Concealed Element

Utilizing the Show Hidden Lines Tool in Revit for Enhanced Element Visibility

Discover the functionality and uses of the 'Show Remove Hidden Lines' tool in architectural modeling. This tool comes in handy when there is a need to illustrate something underneath a filled or masking region as a dashed line.

Key Insights

  • The 'Show Remove Hidden Lines' tool can be used to reveal elements underneath a masking region by displaying them as dashed lines. This is particularly useful when showing features such as floor slabs that are concealed by other elements.
  • The dashed lines are not static but dynamically linked to the model's elements. If changes are made to the model, such as altering the thickness of a slab, the dashed lines adjust accordingly, providing an accurate representation of the model at all times.
  • In addition to the 'Show Hidden Lines' tool, the 'Remove Hidden Lines' tool can be used to undo the command, offering flexibility and control over the visibility of concealed elements within the model.

In this video we're going to look at a tool called Show Remove Hidden Lines. There may be a time when a filled or masking region will conceal something underneath that you want to show as a dashed line. The Show Hidden Lines tool allows you to do this.

Let's go to our View Enlarged Elevation Southwest window. Draw a masking region with the edge style set to Wide Lines. Now what we're going to do is draw a rectangle where the top edge of the masking region is going to align with the top of the first floor slab.

And then we're going to simply draw a rectangle large enough to extend out past the crop region edges. Essentially what we're going to do is mask everything below the floor line, which would be the floor slab and the topography fill. Let's hit the green checkbox to finish.

Now let's go to the View tab in the go to the Graphics panel and select Show Hidden Lines. So the first thing is selecting the element to show hidden lines through. And in this case what we're trying to do is to show the floor slab dashed past this masking region we just drew.

So I'll select the masking region first and then the second pick is going to be selecting elements that will show hidden lines. And that is going to be our floor slab. Now this dashed line is directly related to the thickness of the pad that creates the first floor slab in this model.

If I were to select that pad and change its type so that the thickness was something different than six inches, that dashed line moves along with it. So it's a little bit more powerful than just drafting a line on top of the model. It actually will move with the model changes.

But let's go ahead and undo that change and leave the slab at six inches. Note that you can undo this command by using the tool Remove Hidden Lines as well. In the next video we're going to look at a tool called Cut Profile.
