When you create SOLIDWORKS drawing views, you have the option of assigning the scale of each view. If set as Sheet Scale, they will be linked to the overall scale assigned in the drawing properties (as seen in the Title Block). Auxiliary, Detail and Section Views will automatically add a label indicating the scale if it’s different than the Sheet Scale. However any other views (i.e. Front, Right, Isometric, etc) SOLIDWORKS won’t automatically add labels by default if the scale is set to something other than the Sheet Scale.
To add a SOLIDWORKS scale label by default on all other views, there are options in the Document Properties for ‘Orthographic’ and ‘Other’ view types. ‘Orthographic’ views are your standard Front, Top, Right, etc. The ‘Other’ views would be Isometric, Dimetric, etc. Simply enable the option “Add view label on view creation” and make sure the label options have it set as you wish for Scale and Delimiter. Below I have them set to “Per standard” to pick up the ANSI standard of labels.
Now any NEW view added to your drawing will have a SOLIDWORKS Scale Label automatically added to any drawing view, but only if the view is set to a scale that doesn’t match the Sheet Scale.
Be sure to enable these options in your Drawing Templates to keep these settings for all future drawings.
