Dimensions in Drawing Views

There are two types of dimensions for documenting the drawing views of the tube and pipe assemblies:

Model dimension: Controls the features that are applied during sketching or creation of the feature. Autodesk Inventor Tube & Pipe can access the model dimensions of components and place them in a drawing view. You can then retrieve them to display the overall dimensions of pipe runs.
Drawing dimension: Added in the drawing view for further documentation using the General Dimension command on the Annotate tab. It does not affect features or parts. You can add general dimensions, baseline dimensions, ordinate dimensions, and so on.

You can use the commands on the Annotate tab, shown in the following image, to add dimensions. Pause the cursor over each image to view the tooltip.
