I am not sure if this is the correct forum to post this, but I am having trouble creating a feature in a part. I don't have any idea where to begin.
Basically I would like to profile a beveled edge along a curve with another curve being the centerline. It's difficult to explain without a picture, so here's one.
Instead of the face in grey being flat, I'd like it to have a beveled edge that meets in the middle of the curves.
Any ideas on how to model this?
Thanks,
Lee.
Kelvin,
Thanks for taking the time to attempt it, but it wasn't what I had in mind.
Think of a sword edge, where the middle of the sword is beveled towards the edge. I'm trying to model it along those lines. So, I was going to draw a spline through the middle of the model on the grey face, and have that the centre of the bevel, with the centre of the bevel being on the same plane as the top of the model, going towards the curved edge. Kind of like this: (Excuse the poor sketch.)
I thought there would be a tool to help me do this but I just can't figure it out. I'm not asking for anyone to do the work for me, just suggestions. (Although I wouldn't skold anyone for doing it either! )
Lee,
I think you are going to need to use surfacing techniques to create what you want.

Lee,
Sorry, for stating the obvious. I just realized you had posted your query in the Surfacing forum. DOH!!!
Your problem is a bit of a challenge. I am hopeful some of the users more skilled at surfacing will chime in here.
Cheers,
Anna
Lee,
As Kelvin and Anna have suggested, this is probably going to be a surfacing exercise. Disallowing the crowned trim, you'll have to create additional "spines" for the peak of the letters then (delete front face first) sweep surfaces and then "cap" them using Fill surface and then knit them back in with the extruded surafce as shown below.

Thanks for the suggestion/help Mark. I'll give it a shot.
Should be interesting!
Lee,
I could not open your file because it was created in a future version (SW2010?), but I would have tried to create the part with a loft. You may not be able to loft to a line, but perhaps it would loft to a very thin sketch. And then mirror the part.
I can't imagine how a champfer could be so variable to result in a knife edge.
Create a plane about .3 to.4mm (or your preference) above the top letter surface, project your center spline to there
draw another sketch on the surface and project your letter outline, cut down the lines until it goes from tip to tip of one arm of the letter, but only on one side of the arm and only up to the rounded end.
draw a 3d sketch from the end of the upper line to the end of the lower line, another 3d sketch at the other end of the arm
(note at this stage the 4 3d lines going from the upper to lower surface at the ends are 4 *separate* 3d sketches)
loft between the upper and lower sketch using the 3d lines as guide curves
note when picking lines the point you click on them affects how the loft builds, try not to twist
do the same for the other side of the loft surface
draw another sketch on the top letter surface, project the curved end of the arm, another sketch the other curved end, you have to keep all lines picked in separate sketches for loft and boundary surface to work.
boundary surface the round ends using the edges already made and the curved end sketch as a guide line.
when you have all the upper surfaces build a planar surface on the bottom using all the edges of the other surfaces, stitch and form solid
