+ | This is for an intended print scale of 1: | ||
+ | |||
+ | Then to scale from mm to inches: | ||
+ | |||
+ | - Select all, by command (Tools - Select - Select All), or by pulling up a window around it. | ||
+ | - Scale (Tools - Modify - Scale) | ||
+ | - Specify reference point, normally best 0,0. Enter. | ||

+ | To adapt the Drawing Preferences to inches: | ||
+ | |||
+ | - Set Main Units:\\ {{: | ||
+ | - Adapt Dimensions. You could do it with General Scale 1/25.4, but better let it at 1 for possible later print scaling and change the size values individually. You can later use these settings for all your inches drawings.\\ {{: | ||

+ | There isn't a circular dimension tool for annotating arcs, but we can use one of the existing dimension tools, and then manually edit the label. | ||
+ | |||
+ | This really only works convincingly on segments of circles, although the approach could be applied to a continuous string of line entities, at a push, maybe with the '' | ||
+ | |||
+ | **Step-by-step example:** | ||
+ | - draw a circle, centred on a grid point :: '' | ||
+ | - draw two lines, from centre to perimeter, to define a segment :: '' | ||
+ | - divide the circle at the two lines, to create an arc (two, actually) :: '' | ||
+ | - select the arc to find its length in the status bar | ||
+ | - create an angular dimension annotation between the two lines :: '' | ||
+ | - edit the dimension properties, defining a new label with the length of the arc :: '' | ||
