About Scaling Labels in Drawings

Labels are scaled relative to the drawing scale in model space, and are scaled to the assigned text height in paper space, regardless of the viewport scale.

Model space scaling

In model space, label text height is controlled by the drawing scale and the text height as specified in the label style.

For example:

• In a 1:50 scale drawing, with the label text height 0.1, the labels are created at a height of 5'.
• In a 1:100 scale drawing, with the label text height 0.1, the labels are created at a height of 10'.

Paper space scaling

In paper space, label text always appears at the same height regardless of the paper space viewport scale.

For example, label text height set to 0.1 appears as 0.1 inch on the plotted sheet, regardless of viewport scale or zoom level.

You must use the REGENALL command to update the label display on the screen when you either change the paper space viewport scale or zoom.

Scaling of Xrefs

Labels in drawings that you xref also respect the scale of paper space viewports, so you can create project documentation in paper space at the correct scale for several drawings at the same time.

Note: To label an xref object, the scale of the inserted xref is must be 1,1,1.

Recommendations for managing AutoCAD Civil 3D labels in a viewport

When working with labels in a viewport, do not use the Annotation Scale at the bottom of the drawing window as this will change the viewport scale.

When working with labels in a viewport, you should use one of the following methods:

• Use the Standard Scale in the View Port Properties Palette window. This will not change the Annotation Scale.
• Use the zoom command in the viewport to get the desired viewport zoom scale.

Note: You can reset dragged labels per viewport.
