Freezing a layer in a viewport hides that layer inside one specific window while leaving it visible everywhere else. It is different from globally freezing a layer, which removes it from the whole drawing. Per-viewport freeze lets a single model feed many sheets that each show a tailored selection of layers — a structural plan here, a furniture plan there, both from the same geometry.

This guide uses VP Freeze in the Layer Properties Manager to switch a layer off in just one viewport, then covers freezing layers for new viewports automatically and the viewport-specific overrides that go along with it. It is one of the most useful layout skills, because it is what lets one drawing serve several purposes without duplicating anything.

Per-viewport freeze versus global freeze

There are two kinds of freeze. A global freeze (the regular Freeze column) hides the layer in the whole drawing — every viewport and model space. A VP Freeze hides the layer in the current viewport only, leaving it visible in every other viewport and in model space.

The difference is what makes layouts powerful. The same model can produce a clean architectural plan in one viewport with the structural grid frozen, and a structural plan in another viewport with the furniture frozen — no separate drawings, no copied geometry, just different per-viewport freeze settings.

Step 1 — Activate the target viewport

Move to the layout and double-click inside the viewport where you want to hide a layer. The border thickens, confirming the viewport is active. VP Freeze applies to whichever viewport is active, so you must be inside the right one before you change anything — freezing while no viewport is active does nothing useful.

If you have several viewports on the sheet, be sure you are in the correct one. Freezing a layer in the wrong viewport is an easy mistake to make and a confusing one to track down later.

Step 2 — Open the Layer Properties Manager

Type LAYER (or LA) to open the Layer Properties Manager. With a viewport active, you will see extra columns that only appear in a layout: 'VP Freeze', and override columns for VP Color, VP Linetype, VP Lineweight and VP Plot Style. These are the per-viewport controls, separate from the global columns to their left.

If you do not see the VP columns, you are probably in paper space without a viewport active — double-click into a viewport first. The VP columns are the heart of per-viewport layer control.

Step 3 — Freeze the layer with VP Freeze

Find the layer you want to hide and click the snowflake icon in the 'VP Freeze' column (not the regular 'Freeze' column). The layer immediately vanishes from the active viewport while staying visible everywhere else. Click the icon again to thaw it in that viewport.

You can VP-freeze several layers at once: select them all in the list, then click VP Freeze for any one of them to toggle the whole selection. This is how you quickly strip a viewport down to, say, just the structural layers for a structural plan.

Step 4 — Apply viewport overrides for colour and line weight

Beyond hiding layers, the VP columns let you override a layer's appearance in one viewport. You might keep a setting-out grid visible but VP-override its colour to a faint grey so it reads as background information on a presentation sheet, while the same grid plots bold on the engineer's viewport.

These overrides — VP Color, VP Linetype, VP Lineweight, VP Plot Style — only affect the active viewport, exactly like VP Freeze. They are how one model produces sheets with different graphic emphasis without ever touching the underlying geometry.

A worked example: two sheets from one model

Picture a single floor plan that has to produce both a furniture layout and a structural plan. In the first viewport, activate it and VP-freeze the structural grid and column layers — the sheet now reads as a clean furniture plan. In a second viewport on another layout, activate it and VP-freeze the furniture and joinery layers instead, leaving the grid and columns visible — that sheet reads as the structural plan.

Nothing was copied and no geometry was duplicated; both sheets draw from the same model, so a change to a wall updates everywhere at once. This is the practical payoff of per-viewport freeze: one coordinated model, many purpose-built sheets, with no risk of the drawings drifting out of step with each other.

Freezing layers in new viewports automatically

The 'New VP Freeze' column controls what happens for viewports you create later: a layer set to freeze in new viewports will start frozen in any viewport you cut from now on. This is handy when a layer — construction lines, say — should be hidden on sheets by default but stays available to thaw where needed.

There is also the VPLAYER command for the same controls from the command line, useful in scripts or when you prefer typing. Between VP Freeze, New VP Freeze and the override columns, you have full control over how each sheet reads from a single shared model.

Questions

Frequently asked

What's the difference between Freeze and VP Freeze?+

Freeze hides a layer in the entire drawing — every viewport and model space. VP Freeze hides it in the active viewport only, leaving it visible in other viewports. VP Freeze is what lets one model feed sheets that each show different layers.

Why don't I see the VP Freeze column in the Layer Manager?+

The VP columns only appear when a viewport is active in a layout. Double-click inside the viewport you want to control, then open the Layer Properties Manager and the VP Freeze and override columns will be there.

Can I freeze a layer in one viewport but show it in another?+

Yes — that is exactly what VP Freeze does. Activate the first viewport and VP-freeze the layer there; it stays visible in every other viewport. Each viewport keeps its own independent VP Freeze settings.

How do I keep a layer hidden in viewports I haven't made yet?+

Use the 'New VP Freeze' column in the Layer Properties Manager. A layer set to freeze in new viewports will be frozen automatically in any viewport you create afterwards, until you thaw it there.
