You have to make sure your annotative object has the proper Annotative Scale attached to it. Right click -> Annotation Scales. The list should contain the scale you are using in your viewport. You may also want to check into ANNOAUTOSCALE.

Adjust or remove annotation scale In the Properties palette, check if Annotative is set to Yes. If so, do one of the following: In paper space, select the viewport and change its scale to match that of the annotative object. In model space, set Annotation to No for the affected objects.

Causes: The drawing objects are set to use annotative scaling. This is controlled within the defined text and dimension styles but can be altered via the Properties palette once an object has been created in the drawing.

Go out to PS, make a viewport current, then issue the ZOOM command, type O for object, type L for last, hit enter. You will see your objects now, continue from there.

Check the layer properties when you open the viewport with missing dimensions. It might be the layer properties is overriden for that specific viewport. And also check with annotation scaling. It’s possible that the dimensions are not showing because the annotation scale is different with viewport scale.

Click Structure tab Build panel New. Find The New dialog box is displayed. Click the Annotation View tab. In the Component section, select the Create annotation view of option and from adjacent the drop-down list, select the component you want to create an annotation view for.

To restore the missing viewport, do the following:

1. In the Layer Properties Manager, make sure the layer that contains the viewport geometry is not turned off or frozen.
2. Go to the layout tab that contains the problem viewport.
3. From the Properties palette, select the Quick Select button on the top right.

The default settign is YES. using teh block editor, i changed this setting to NO, and it fixed teh problem. It has something to do with the annotative scale settings and the block not showing properly in your paper space viewport when this setting is turned on.

Two ways to fix it are to select another viewport scale then change it back or type CANNOSCALE at the command line and type in the exact scale name including any spaces: 1:10, 1″ = 10′, etc. Civil 3D 2016. I have annotative multileaders in an xref that do not display in the plan sheet viewport.

The Viewport Scale property and the Annotation Scale property for the viewport take the same value. Post a question. Get an answer. Get answers fast from Autodesk support staff and product experts in the forums.

If you are in model space, make sure the Annotation Scale drop-down list on the status bar (Find)shows the scale you want annotative objects to be displayed at. For layout viewports, select the viewport and, on the status bar, click Viewport Scale Sync (Find).
