How to taper a character, please assist

Anonymous
Not applicable

I am very new to 3D drawing and Fusion360 and I can not get the following solved.

I have a capital N and a lowercase n that I like to extrude and give it a taper of 20°. With the capital N it is not a real problem, but the lowercase n does not allow me to taper it more than 1°.

Can anyone give me a clue or direction I can do this?

Thank you all!

Correct, you'll probably  have to do this surface by surface in the patch workspace or find another workaround.

Past 1.3 degrees the surface framed in recd will collapse into itself.

Thank you TrippyLightning for your quick reply.

So, that means I had to extrude and taper the curves and straight lines separate and patch them together?

Doe I understand you correct?

Sort off. I cannot describe a straight forward workflow and it will take some experimentation to get to an acceptable result . I am assuming that the 20 degree draft angle would not have to be maintained precisely and if you are in an approximate range that would satisfy the goal.

If you have to precisely maintain the 20 degrees than starting with imported sketch geometry is likely not going to get you there.

Thanks for pointing me to the fact that I probably need to draw the characters in Fusion itself. I hoped there was a kind of more simple way to achieve it, unfortunatly not so.

While that will help some, the reason the draft command does not work is because several of the curved segments would Crete self-intersecting geometry @ 20 degrees of taper and Fusion 360 does not allow that.

An observation:  after cupping the Front Face of the "N", the revealed edges are no longer straight, rather, bulging toward the lowest point of the surface.    If you'd like those edges to be straight, you'll need to create a gross curved surface where you'd like the Face to be located, then Project to or Slice that surface.    Moreover, were you to follow that course, a consistent 20 degree angle relative to the "Back" Body isn't really possible without displacing/curving the point of contact with Back.

Thank you for your reaction Mavigogun. I noticed the strange lines inside the N but i could not fix it. So i am very happy with your solution that could fix it. But, i am so new to Fusion annd 3D that i can hardly understand what you mean. Can i ask you to show me what your solution is, or does this involve a lot of time. It would be very much appreciated, thanks in all cases.

Slice is like a cookie cutter.    Here, I've Extruded a Sketch curve in the Patch Workspace, then Sliced the resulting Patch surface with your "n" Sketch Profile:

Read more about Split here- http://help.autodesk.com/view/fusion360/ENU/?guid=GUID-BA98BF29-74B5-443D-AA06-02EE52CD7ED5  -and you can learn a lot more about it by searching this forum.

The Sketch tools Include/Project capture geometry in the form of Sketch elements, or transform Sketch elements using exiting geometry.    So, in the case of our "n", if you'd rather work with a Sketch instead of a Body or surface Patch, you could use Project to Surface to produce a curved "n" Sketch-
