The pattern should maintain it’s dimensions as a model element does, hence the name “model pattern”.įor those of you who have a background in AutoCAD, you’ll be happy to know that Revit supports hatch patterns from AutoCAD DWGs.
This is exactly as a user would expect as bricks should not change size based on the scale of a drawing. Revit hatch patterns at 1/4” = 1’-0” scale.Īs shown in the examples above, the diagonal hatch pattern (drafting pattern) changes based on the drawing scale while the brick hatch pattern (model pattern) remains the same. The difference is model patterns remain a fixed size relative to the model, and drafting patterns remain a fixed size relative to the scale of the view that is displayed in.Īn example of the different use cases for each is a brick pattern on the face of a wall versus a crosshatch pattern on a wall. If you’ve been exposed to fill patterns in Revit, you may have noticed that there are two types of Revit hatch patterns, drafting patterns and model patterns. Check out the drawing of the Confederate State Capitol of Arkansas below. Hatch patterns have been used in technical illustration since we were drafting with pencils on paper. They can help denote the material of an element, differentiate a section cut from the surface of an element, and even help identify that an element is of special interest like a clearance area for a piece of equipment. If you are ever wondering why a pattern on an existing element rotates with the element where a pattern on a new element does not, this is most likely the reason.Revit hatch patterns, officially known as Fill Patterns, are a critical graphical element when developing drawings in Revit. With the exception of Show Complete, the default phase filters have new elements set to By Category, and Existing elements set to Overridden. With this setup my View Filter Pattern will rotate with my element for Coarse, Medium & Fine Detail Levels because it was changed from By Category to Overridden: My Phases > Graphic Overrides are set as follows: Let’s look at the following example for #4: When the Graphic Override for a Phase Status has a material applied under the Material column, and you have a View Filter Pattern in the view, the View Filter pattern can Align With Element for Coarse, Medium & Fine Detail Levels. When phasing is involved, and a Phase Filter uses Overridden for one of the categories, check the Graphic Overrides tab. If you happen to have a coarse scale fill pattern, view filter pattern and phase pattern applied simultaneously they should appear in the following priority :Ĥ. If it was overridden to Medium or Fine the pattern would not align because the detail level of the view is being overridden.ģ. If you have patterns not aligning, and the Detail Level is set to Coarse, make sure that the Detail Level under Visibility/Graphic Overrides > Model Categories > Detail Level, is set to By View.
Align with Element does function for all Detail Levels if it is applied in a Phase > Graphic Override > Cut Pattern.Ģ. Align with Element only functions for Detail Level Coarse when used in a View Filter or Coarse Scale Fill Pattern : The drafting pattern needs to be used as a cut pattern in a host. There are 3 important defaults for Align with Element behavior: You can change this to Align with Element, and it will stay aligned to the element with location or angle changes. This means that the pattern will not stay aligned, if applied to a wall as it moves. When you create or edit patterns, the default orientation in host layers is Orient to View. Let’s review some important items to keep in mind…ġ. Often one or more of these may be active at the same time, which may lead to some conflicting results. Phase Graphic Override Cut Pattern - Displays at all Detail Levels Material Cut Pattern – Displays at Medium & Fine Detail Levels View Filter – Displays at all Detail Levels Taking walls as an example, there are several locations you can add a cut pattern to the wall display such as:Ĭoarse Scale Fill Pattern - Displays at Detail Level Coarse
