A proposal of 3D modeling strategy:
Construct basic profile curves using the orthogonal views
- Four curves are drawn from the Top
- four from the front and
- five curves from the
The curves are overdrawn for the purposes of overbuilding
Minimize the number of
Surface construction of the Vacuum builder
The main surfaces on the vacuum is fairly simple to build.
Details will be added in the trimming stage. The surfaces will be
"overbuilt" to make sure the model is "water tight", or in this
case perhaps "air tight". Construct the surfaces by using the
Rail tool or possible the skin
tool as well.
Adding detail to Vacuum Cleaner
Intersect, trim and round the vacuum model.
Build the cavity surface for the handle by revolving the profile
curve. Intersect it with the main surfaces and trim.
Build the handle and add vents to the model. Also add an
embossed surface on the side that "washes" out on either end. Build
it by constructing a profile curve with continuity at both ends and
using the isoparams as start and end profiles as well as generation
curves. Remember to use the patch precision command to get the
isoparams where you want them. When complete - produce curve on
surface geometry and trim the portion of the side surface that lies
beneath the new features.
