Now, lets cap the tubular part.
From the end of the first Line we created in this tutorial, create another line, and make it 10units (mm) long. Now, using Quad option in Osnap create InterpCrv (Curve: Interpolated Points) between two Quad points as start and end, and in the middle top of the 10mm long line:
Trim one half of the newly created curve (arch) with 10mm long line, and that half arch needs to be revolved. I used Sweep1 and followed outer circle. But before that, we need to offset that half arch, and we need to move the inner circle by 2mm right from Top viewport (2mm will be the thickness of our shell – yeah, we still need to do that manually :().
Now, we can use Sweep1 and make two surfaces:
Ok, now, we will make little holes on the rear. From Right viewport make an ellipse 5×2.5mm. Rotate it for 45 degrees, and position like on the image:
Using ArrayPolar make an array of 24 holes. Naturally the center would be the same center of circular surfaces.
I have grouped each row of ellipses, and will extrude them one group at the time so I have more control, and less mess. So, extrude the ellipses and trim with two circular surfaces:
Now, we will make just the same handle and tubular surface, but 2mm smaller. Using all those smaller circles, and smaller curves, we will make inner side of our dryer. You could use offset, but when using it curves are often made out of too much control points, and therefore your surfaces end up with much more isoparms, and we want our models cleaner. You could use Rebuild to make curves better, but then you might loose the original position of your curves. It is a bit tricky, and recreating all the curves, but 2mm smaller is a lot better way.
Now, we need to blend the inner and outer surface where the air blows out.
Next, on the part where the air is sucked in, using FilletEdge and 2mm as radius round that edge:
Lets get back to our first 120mm long line. On the other end (the end there the air blows out from the dryer) create another circle with radius of 6.5mm. The second one from the same center but with 8mm as radius, and another one with radius of 10mm, then one with 16, and one with 18mm radius.Extrude those 5 circles by -15mm (minus is because we need it to go left when looking at it from Top viewport). Do not use Cap option.
Next, you will blendsrf paired circles.
The one in the middle, the smallest circle, using Arc command we will make an arc like on the image below:
Using sweep1 command make a cap:
Using Line or Polyline mimic the image below. I first created one line through the center, and then copied it and rotated by 90 degrees, next, I copied those two and rotated by 45 degrees. Next, each line I offset by 1mm up and down, and deleted the middle line. I have also offset the outer circle by 2mm, and aligned everything in the same cplane.
And for the end of this part we will extrude those curves by 5mm with Cap option set to yes.
