We can also import a block from a CAD file outside the current drawing. We can insert the same block numerous times instead of re-creating the individual geometric objects each time. We can insert, scale, and rotate multiple objects that belong to the same block with a single Using blocks can help us organize our design by associating the related objects into smaller units. In AutoCAD® 2019, a block is a collection of objects that is identified by a unique name and essentially behaves as if it is a single object.

Center lines are also used to indicate the symmetry of shapes, and frequentlyĮliminate the need for a positioning dimension. In between an extension line and a center line. Center lines may also be used as extension lines therefore there should be no gap Dimensions should be placed only on the view that shows the measurement in its When dimensions are placedīetween views, the extension lines should be drawn from one view, not from bothį. Dimensions should be applied to one view only.
