Extruding an augur-like surface

jwlefkoff — Mon, 27 Nov 2023 13:34:54 GMT

In short what I'm attempting to do is extrude the face at pt A in a smooth 90 deg coil like shape to pt B and have it finish parallel to the main XY plane. I've tried using the sketch arc tools but they do not seem to want to connect the two points properly. I then tried a fit point spline only to have the sweep command refuse to work due to a self intersection. I attempted to sweep along the outer edge of a coil but I couldn't get it to level out with the XY plane at the end. I know there's got to be an incredibly obvious way to do this but I just cannot seem to get it to work. Thanks in advance!

Whoops! Totally slipped my mind. It should be attached to the original post now.

@jwlefkoff

Is there a logically Grounded component in your assembly?

Have you used Joints to assemble the components?

Are any and all Moves used correctly?

Are any and all sketches fully defined?

Sorry I totally missed this reply somehow. No there are not any logically grounded components (not even sure what that is). There are not any joints but as far as I’m aware there shouldn’t need to be any? I believe I used all the moves correctly, not sure how you could use them incorrectly? All my sketches are definitely fully defined.

@jwlefkoff

Are you willing to start over from scratch and step-by-step learn how to:

1. Fully define each and every sketch.

2. Identify and use a logically Grounded Component.

3. Use logical Joints (rather than Moves) in assembly of Components.

I suppose I’m willing to learn it. I just don’t see why it’s necessary compared to the way I’m doing things which has always worked. This has strayed very far from my original question.

Then you should not indicate the problem is solved.

The ramp is likely solved with Sweep or Loft with rails, depends on the geometry existing or required.

Might help….

@jwlefkoff

No, in the real world this has never worked.

There must be realistic clearance between mating/sliding components...

OK, let's start over from scratch step-by-step.

Start a new file.

Sketch a rectangle on the ZX plane above the Origin and dimensioned as shown below.

Add a Construction line from the midpoint of the horizontal line on the bottom of the rectangle to the Origin...

Note the colors of the geometry.

Now add a Vertical constraint to the construction line and add the 18.45 dimension...

Note the color change of the geometry.

Attach your new *.f3d file here for next set of steps.
