Continuing the mechanical project from Chapter 4, Structuring Projects and Following Standards, we are going to measure the volume by applying text and creating a table. DraftSight, as other DWG softwares, is dimensionless, we assume the length unit is millimeters (mm)
Open the drawing
PROJECT1-CH4.DWG
.To calculate the volume of both parts, the best way is to use a new layer to create a contour. Create a layer called AUXILIARY, with a different color and activate it.
With the
POLYLINE
command, create a closed polyline contouring the left view by applying the Arc option on the top fillets. TheGETPROPERTIES
command applied to this polyline indicates an area of7653.429
mm2.
Apply the
EDITPOLYLINE
command to create a polyline from the two arcs and lines of the top hole. TheGETPROPERTIES
command of this polyline indicates an area of278.54
mm2.The circular hole area is
176.715
. So the total area is7653.429-278.54-176.715
, that is,7198.17
mm2. The width of each part is 20mm, meaning...
