How do you make a sloped half moon?

3D Design Volume Model

Hello

After several tries and a search for a solution in vain, I explain my problem to you.

I want to model on SW a kind of sloping half-moon... See the image.

What solution do you propose to me?

Thank you in advance.

Cdlmt,

Hello, nothing could be simpler. You make a rectangular sketch. Then a helix sketch. You do a sweep, finally a removal of material to have the base flat.

 

Kind regards

 

Attached is a photo to get a little idea;)

Hello 

To put it simply, I would have drawn my half moon on the front like in your photo and given it a fake thickness and then removed the material using the face perpendicular to that of the half moon giving it the shape you wanted.

Thank you for your answers.

ac cobra 427: This solution does not correspond to the reality of the part because the part imposes an angle of rotation. It was my 1st idea too...

G.: It seems ideal and very simple, but I'm drying up on the removal of material... Do you give an angle to your sketch?

Here's where I am...

your half-moon is 180°

what is the elevation (high level - low level)

You rotate 180° so the pitch of your spiral helix sketch must be 2 times the height of your elevation

see attached file SW 2012

Thank you very much for the help given!!

I managed to make the desired shape!! GT22 sending the file helped me a lot!

I now attack the counterform of the 1/4 turn.

Using sketch-on-sketch projection, you can use a depth (off-plane sketch), if you want to dimension an angle you can create a construction sketch that determines the offset of a plane, or use two perpendicular planes to make both of your sketches.
