You can add redline markups to a Navisworks viewpoint, an animation, a selection set, a search set, a clash result, and a TimeLiner task. Redlines can consist of objects such text, and as revision clouds, ellipses, lines, and arrows. When you add a redline, the redline is added to the current viewpoint. If you are working in a named viewpoint, the redline is added to that viewpoint. If you are not working in an existing viewpoint, a new viewpoint is created.
The redline tools are located on the Review ribbon, in the Redline panel. Here, you can see the various redline tools. The redline Text tool has its own dedicated button. When you expand the Draw split-button, you can select one of the six redline tools for creating shapes. The Color and Thickness controls enable you to modify the redline settings. For example, before creating a redline, you can expand the Color panel and choose the desired color. You can also click More Colors… to open a Color dialog. Here, you can choose any of the basic colors or click Define Custom Colors >> to expand the dialog so that you can use a color mixer to define a custom color and add it to the custom color swatches below the basic colors. For this exercise, click Cancel to leave the color set to Red.
You can use the Thickness control to set the redline thickness by either entering a value or using the spin box controls. The Thickness can be any value between 1 and 9. Note that you must select the Color and Thickness before you create a redline; these settings cannot be changed after the redline has been created. Also, the thickness only applies to lines; it does not affect redline text, which has a default size and weight that cannot be modified.
First, orient the model as desired. For example, orbit and zoom in on the tops of the two exhaust stacks. To add redline text, on the Review ribbon, in the Redline panel, click Text. In the Scene View, select the point where you want the text to be located. The program displays a dialog box so you can enter the redline text. Type, “Maintain 4-foot minimum centerline distance”, and then click OK. The redline text is immediately added to the view.
Since you were not working in a named viewpoint, in the Saved Viewpoint window, you can see that a new viewpoint has been created. Right-click that view and change its name to “My Redline 1”. Redlines are only visible in the viewpoint in which they were created. When you orbit in the Scene View, the redline disappears. When you restore the viewpoint, you once again see the redline.
To add an arrow, on the ribbon, in the Redline panel, expand the Draw split-button, and choose Arrow. Then, in the Scene View, click to place the tail of the arrow, and then click again to place the arrowhead.
To add a redline cloud, expand the Draw split-button and choose Cloud. Click in the viewpoint to begin drawing the arcs of the cloud. Each time you click, a new point is added. Clicking in a clockwise direction draws regular arcs, while clicking in a counterclockwise direction draws inverted arcs. To complete the cloud, right-click in the Scene View.
To add a redline ellipse, expand the Draw split-button and choose Ellipse. Then, click and drag a rectangle in the viewpoint to outline the ellipse. When you release the mouse button, the ellipse is placed in the viewpoint.
To draw a freehand markup, expand the Draw split-button and choose Freehand. Then, click and drag the mouse to draw in the viewpoint.
To draw a single straight line, expand the Draw split-button and choose Line. Then, click in the viewpoint to select the start and end points for the line.
To draw a sequence of connected lines, expand the Draw split-button and choose Line String. Then, click in the viewpoint to begin. Each time you click, a new point is added to the line string. When the string is complete, right-click.
Once redlines have been created, they can be modified in a few limited ways. For example, redline text can be moved and edited. To move redline text, right-click the text in the Scene View to display a shortcut menu and choose Move. You can then click to specify the new text location. To edit the actual text, right-click the text in the Scene View and choose Edit to open a dialog box. Change the text as needed, and then click OK. You can also right-click redline text and delete that text.
Note that there are no similar tools available to modify redlines. But you can erase redlines in a viewpoint. To erase redlines, on the Review ribbon, in the Redline panel, click Erase. Then, click and drag to create a selection rectangle. Only those redlines entirely inside the rectangle will be erased. Those outside or crossing the rectangle boundary will remain.
The Erase tool only selects redlines. If you drag a rectangle surrounding the entire model, only redlines are selected.
Again, remember that redlines are only visible in the viewpoint in which they were created.
