Aircraft Nose

Postby Stephen50 » Tue Feb 05, 2019 11:54 pm

Working on the front on view of a passenger aircraft created most of the components engines, wings, rudder, landing gear, and tail. The only point of completing this file is the nose. I created a shape using both the curved profile and the angular profile each set to 90 degrees attempted to sculpt to no avail unable to obtain the desired shape. In my opinion the nose needs to have a gradual curve on the sides and a smooth nose can't figure how to achieve it. The height of the nose is limited to .40 the material thickness is 1.25 Any and all suggestions are welcome.

Tough to give you any advice without knowing your point of view. Side profile? Straight on? Some combination?

The sketch or pic you are working from would help too.

Straight on or looking right at the nose of the aircraft

Stephen,
That leaves a mountain of possibilities. No doubt there are many here that can guide you on the right path. But we have no idea what type of aircraft the reference is. A screen grab and a bit more information would do wonders.
We all could spend hours guessing on what you are trying to do.
Glad to help no doubt if we can just need a bit more information. :lol: :lol: :lol:

I believe Stephen has been working on this for a few weeks. He posted a crv3d file in a thread linked here:

I want to create a front view of a nose of an aircraft from the B-737 series with winglets, the ends of the wings are turned up for fuel efficiency. What I've created is a round circle with a rounded top not what I desire.

Have you tried a two-rail sweep? Make a tiny (.005) circle in the middle, and then a circle the diameter of your nose. Do two rail sweep with "fill center" checked.

Mike-S; Your explanation is straight forward one small problem still, would you send me a sample of the vector you used to create the cone. Whatever, I try I end up with a say a small crater in the center even though I checked fill center.

The vector is a trimmed ellipse.
Don't know why you get the dimple. Zoom way in on the tiny center circle to make sure the start node is at the same o'clock position as the larger circle. Also that both circles have the rails running in the same direction.

If you're getting this, you selected the rails in the wrong order.

Mike-S: Listed are the steps I used in an attempt to create cone
1. created inner circle .005
2. created outer circle .75
3. created ellipse clipped bottom created open vector
4. clicked on two rail sweep
5. highlighted outer circle first
5. held shift key highlighted inner circle
6. clicked use selection
7. verified rail direction on both inner and outer circles were going counter clockwise
8. verified both start nodes were inline with each other
9. selected vector (ellipse) to use as cross section
10. clicked on outer circle to attach ellipse
11. ensured only fill center was available other two were grayed out
12. hit apply
13. ended up with dimple

Skip your Step 10 (no need for that step)

If the shape has a dimple after Apply, right-click on the outer circle and select Reverse Rail Order, then Apply again
