Single line face text with draft

TomBarosso3248 — Mon, 21 Jan 2019 13:06:40 GMT

Hi,

I need to create a series of stamps that will be used to mark parts in a press. The stamps will have a single line sharp face with a 45 degree draft angle. (See the picture below for an idea of what I’m talking about.) It seems like a pretty simple task but I can’t seem to find a solution.

Thanks,

Tom

Can you Attach the *.ipt file of your attempt here?

I haven't even come close. I thought I could do something by starting with embossed text, but there's a limit to the draft before it self-intersects. It seems that I need to start at the single line at say 1mm above the flat surface and add draft to the single line, not start at the base and extrude out.

I think you will have to sketch your own custom font - not use sketch text.

Then use Loft as you attempted earlier.

Create a sketch..

Place the text you want..

Extrude it with a -45 deg taper.. (see more tab on the extrude dialog box)

(I just used Arial font BTW)..

@mcgyvr, could you post the .ipt you used? When I try this I get an error message when I try to add the draft; any angle, + or -. I have attached my attempt. Maybe it's the font I picked?

Thanks.

Use Arial font

And you will need to play around with the depth vs angle vs font size..

Do you really need this sort of detail in your Inventor model?

@mcgyvr Well, I was toying with the idea of machining the stamps (programming in HSM) so I would need to model them.

Gotcha..

That "might" work out well assuming you can get the single point for the engraving tool routine to follow properly..

Should be doable.. (I haven't installed HSM yet on my new computer to answer concretely.. )

How many of these are you going to make? I did this by placing text on an offset plane, converting to geometry (single line SHX font), manually placed coincident constraints at each intersection (none of the line geometry is constrained at all), extruded each profile to surface twice (once at 45°, once at -45°), created a capping workplane for the open ended characters, sculpted them all together (12 surfaces + workplane), created a 45° surface across the open ended characters, used Replace Face to add draft to the open ended characters.

Now, that wasn't hard, was it??! Your choice of line fonts is pretty limited, and as I mentioned above, converting text to geometry leaves everything unconstrained (and also uneditable!), so I would go with @JDMather's recommendation to create your own characters from lines and arcs.

This would be a really tedious procedure for creating a whole library of stamps, but for a few, definitely possible.

@SBix26 You make it sound so easy. I would have to make about 6 of them. I think I'll try some machining with the model you made and then decide if it's worth my time to proceed.

Thanks everyone for the responses.
