Recommendations for Scaling Cells on ODOT plans:
Basemap design files are used to draw existing and proposed plan view information for the entire length
of the project for both Roadway and Bridge projects. All basemap information shall be drawn in the
default Design model. The location and dimensions of all plan view basemap design file information shall
be drawn using real world dimensions at a 1:1 scale. Cells are to be placed in the basemap at a scale of
one (1), with the Place Active Cell’s Annotation Scale Lock toggled on so the Model Properties
Annotation Scale feature can be used.
When attaching the basemaps as References to the “Sheet” model, set the Model Properties
Annotation Scale for the appropriate sheet scale. Changing the Model Properties Annotation Scale
value will cause the display of the Cells to change according to the value selected. This will affect cells,
text and dimensions drawn in the active file, as well as referenced graphics depending on the settings
when the references were attached.
All cells should be placed at a scale of one (1) with the Place Active Cell’s Annotation Scale Lock
toggled on and then scaled using the Model Properties Annotation Scale as shown below.
