CAD work rarely happens in just one drawing.

An engineer may keep a current design open while referring to an earlier revision. A mechanical designer may copy standard details from a library drawing. An architect may need to compare two plans side by side.

Traditionally, several DWG files can remain open at the same time, but users still rely heavily on drawing tabs to move between them.

GstarCAD 2027 introduces Multiple Top-Level Windows, allowing an open drawing to be dragged out of the main application window and displayed as a separate floating window.

At first, this may look like a simple interface improvement. But it changes something more important:

how multiple drawings can remain visible and usable at the same time.

From Drawing Tabs to Independent Windows

Drawing tabs make it easy to keep several DWG files open, but multiple open drawings do not necessarily mean multiple visible drawings.

Consider two files:

Assembly_Current.dwg

Assembly_Revision.dwg

In a traditional tab-based workflow, users may repeatedly move between them:

Drawing A → Switch Tab → Drawing B → Switch Back

Both drawings remain open, but the visual context changes each time.

In GstarCAD 2027, a drawing tab can be dragged outside the main application window and displayed as an independent floating window.

The two drawings can then remain visible side by side:

Drawing A ↔ Drawing B

The DWG files themselves have not changed. What changes is how they can be arranged and accessed during the workflow.

Instead of keeping every drawing inside the same visual frame, users can organize multiple DWG files across the desktop according to the task at hand.

Why Multiple Monitors Make This More Useful

The advantage becomes especially clear on workstations with two or more monitors.

For example:

Monitor 1
Current project drawing

Monitor 2
Reference drawing

A mechanical designer might keep the main assembly drawing on one screen while displaying a standard detail library on another.

An engineer checking revisions could place the previous version beside the latest drawing.

This means the reference no longer needs to disappear whenever the user returns to the active project.

The real benefit is persistent visual context.

Instead of repeatedly switching drawings to confirm a dimension, locate a detail, or check an earlier design, the relevant information can stay visible while work continues.

A More Practical Way to Compare Drawings

Revision review is one of the clearest applications.

Imagine working with:

Pump_Station_Rev02.dwg

and

Pump_Station_Rev03.dwg

When both drawings are visible at the same time, users can manually inspect areas such as:

• Geometry changes
• Updated dimensions
• Revised notes
• Equipment locations
• Modified drawing details

This does not mean Multiple Top-Level Windows replace a dedicated drawing comparison tool.

The feature itself does not automatically detect or highlight differences.

Instead, it provides a better workspace for manual visual comparison.

That matters because many drawing checks are not simply about identifying whether something changed. Engineers may also need to understand the surrounding geometry, compare annotations, or visually confirm how a revision affects the rest of the drawing.

Keeping both files visible can make that process more direct.

Reusing Content Across Drawings

Another common multi-drawing task is reusing existing CAD content.

Engineering teams frequently work with standard details, blocks, symbols, components, notes, and geometry from previous projects.

With a tab-based workflow, this may require repeated switching:

Find Detail → Copy → Switch Drawing → Paste → Switch Back

With Multiple Top-Level Windows, the source and destination drawings can remain visible at the same time.

Users can copy content from one drawing and paste it into another while keeping both drawing contexts on screen.

The COPY and PASTE commands themselves have not changed. What improves is the workflow around them:

less tab switching, clearer source and destination context, and easier reuse of drawing content across DWG files.

Why Window Management Matters in CAD

Switching a drawing tab only takes a moment.

But professional CAD work is made up of thousands of small interactions.

When users repeatedly move between drawings, the interruption is not only the mouse click itself. They may also need to recover the visual context:

Where was that detail?

Which revision was I checking?

Which component was I going to copy?

Was this note in the reference drawing or the current project?

This is a form of context switching.

Multiple Top-Level Windows reduce some of that switching by allowing related drawings to remain visible together.

That makes the feature particularly useful when working with:

• Drawing revisions
• Standard detail libraries
• Reference drawings
• Multiple related DWG files
• Multi-monitor workstations

The feature does not change how CAD geometry is created.

It changes how easily users can work across the drawings that contain that geometry.

A More Flexible Multi-Drawing Workspace in GstarCAD 2027

The workflow is straightforward:

Open multiple drawings → Drag a drawing tab outside the main window → Position the floating window where needed

From there, the desktop can be organized around the task.

Users can:

Compare drawings side by side.

Keep reference information visible while editing.

Place different DWG files on separate monitors.

Reuse drawing content with less tab switching.

This is what makes Multiple Top-Level Windows more meaningful than a simple interface change.

Traditional drawing tabs solve the problem of keeping multiple files open.

Multiple Top-Level Windows go one step further by helping users work with multiple files visually at the same time.

Sometimes Better CAD Workflow Is About Seeing More

Not every meaningful CAD improvement needs to introduce a new drafting command.

Sometimes the drawings are already open.

The information is already available.

The real limitation is simply that users cannot see what they need at the same time.

Multiple Top-Level Windows in GstarCAD 2027 turn multiple open drawings into a more flexible multi-drawing workspace.

For users who regularly compare revisions, reference other drawings, reuse standard content, or work across multiple monitors, the value is straightforward:

less switching, more visible context, and a more direct way to work across multiple DWG files.
