Extruding text to a point

[Anonymous]

I am trying to extrude a text from a curved surface, but with a 45deg angle all around.

It is part of a roller, which embosses text into a metal extrusion, therefore the text must be sharp in the centre like a stamp.

I have managed to get the text onto the curved surface with no issues, and I can extrude it straight out fine, however if I try to put a chamfer or draft or taper angle on the text extrusion it just won't do it and throws up an error.

Please help me get onto the right direction, this is really frustrating. I think it may be something to do with the geometry of the text but I'm not sure.

There are some fonts that will be impossible to do anything like this with.  Don't know which one your using, so I can't check that.

If you need to be very exacting in your outcome, you may need to do this with a series of lofts in patch space.  If some variation is ok, there may be some less demanding approaches.  can you describe your intended outcome a little more?  (or hand sketch it?)

Thanks for your reply, 

That was my suspicion about the fonts - I've tried to stick to something simple, DS ISO1. I've also tried a multitude of different fonts. Ideally the font must be engineering style, straightforward and very legible.

So as you can see in my crude sketch above - the centre of the letters must be raised by 0.5mm to a point, in order to press into a material as it is passed under roller.  This is to be cut with a 90deg milling cutter.

Some food for thought...

If you do this as sheet metal, the extrusion will be truly vertical which allows you greater flexibility in doing a chamfer (for example).

Check out my example. This isn't perfect, but it shows you a path worth exploring.

You font makes all the difference here...

Adding draft to text after extruding tends to be more reliable than adding draft in the extrude feature. The problem you'll have is finding a font where all the features are the same width, in the image below you can see even a simple T doesn't work because the vertical part is wider, as for the M well not sure you'll get the to work automatically.

Low (or zero) contrast fonts will help this out tremendously:

Hi Mark, 

What font did you use for the above?

That one was Roboto but Arial give pretty much the same, see attached file.

Solved, thanks guys - I installed a font called Orbitron - it's geometrically sound so chamfered to 0.5 to within 0.01 which is ok for this project.
