# How do I see how my rules do on a model?

Load a model in the IDS editor and the table shows how many elements pass and fail each rule, and the counts follow your changes. A line under the draft also says which classes of the model only general rules reach, with a button to add a rule for each.

## See live counts, step by step

1. Click the field at the top and choose **IFC model**, or drop an IFC model anywhere on the page.
2. Read the **On model** column. It shows how many elements pass and fail each rule. A failure is marked in its own cell. Choose it to see the values that failed. A rule that applies to no element in the model says so.
3. Change a rule. The counts follow your change.
4. For a large model, or one whose last count was slow, the counts are on request. Choose **Update counts** beside the model in the line under the field after your changes.
5. Look at the strip under the draft line. It says how many elements of the model have a rule for their class and how many only general rules, and opens a list of the classes (**Show the classes**).
6. For a class on the list, choose **Add rule** to start a rule for it, **Not allowed** to write a rule that does not allow it, or **Not needed** to leave it to other checks for now.

## Why the strip matters

An element a general rule reaches still passes or fails, but the test was not written for its class, so the draft is thin there. Elements no rule reaches are untested on Results ([untested elements](https://ifcchecker.com/help/untested-elements/)). **Not needed** hides a class for this visit and writes nothing into the IDS.

## The model is optional

A model only fills the lists and the counts. You can write an IDS without one. A model loaded on an empty sheet also drafts the rules most elements carry, and you tighten them.
