What is a Revit ʼDetail Levelʼ (Coarse

ByCADbrief Staff

Short Answer

A Revit Detail Level controls how much model geometry is displayed in a view: Coarse, Medium, or Fine. The most common way to change it is from the view control Bar using Detail Level. Coarse shows simplified components for faster navigation and cleaner documentation. Limitation: not all families display meaningful Coarse representations.

What You Need to Know Before

Warning: Changing Detail Level affects only the current view unless a View Template is controlling it. A common failure is editing a view manually, then having the template immediately override the setting and hide the expected detail.

How to Change Revit Detail Level

  • Command: Detail Level

  • Shortcut: None

  • Quick Steps:

    1. Open the target view, then go to the View Control Bar at the bottom of the revit window.
    2. Click Detail Level and choose Coarse, Medium, or Fine.
    3. If the view does not update as expected, check the view’s View Template in the Properties palette and confirm Detail Level is not template-controlled.

Variables & Settings

  • Key Setting: View Template > Detail Level

  • Expert Setting: If a View Template is assigned and includes Detail Level, manual changes in the view will be locked or overwritten. This is the main control used in professional Revit projects to keep documentation graphics consistent.

Why it Fails

  • Cause 1 (Geometry): The family may not contain a simplified Coarse representation, so the element looks nearly identical in all detail levels.

  • Cause 2 (layers/Locks): A View Template may lock the Detail Level setting, preventing manual changes in the active view.

  • Cause 3 (Command/Logic): Detail Level changes only visual representation, not model accuracy, family visibility settings, or section/detail callout scale behavior by itself.

Quick Fix & Best Practice

  • Quick Fix: Open the view Properties, review the assigned View Template, and either remove template control for Detail Level or set the correct Detail Level inside the template.

  • Manager’s Verdict: Use Coarse for plans, massing, and performance-friendly coordination views; use Fine only when documentation truly needs fabrication-level or component-level graphics.

FAQ

Does Revit Detail Level affect all views?

No, it affects only the active view unless controlled through a View Template.

What does Coarse show in Revit?

Coarse shows simplified geometry, often reducing visible component detail.

Why does Detail Level not change my family appearance?

The family may not have distinct Coarse, Medium, and Fine display definitions.
