Click point 3 to locate the dimension line. To create Linear dimensions click the points 1, then 2 to identify the element to be dimensioned. The Linear dimension tool measures horizontal or vertical distances. The required dimension tool can be chosen from the Dimension drop-down. You can access the dimensioning tools from the Ribbon Annotate tab > Dimension panel. Dimensions allow exact values to be shown on a drawing which can then be used for construction. Measuring distances from a scaled, printed drawing is inaccurate. Notes on a drawing are important to convey design information or clarify intent which can’t be portrayed by linework alone.
