Extruding through Curved surface

Hello,

 

I've done a lot of reading through these forums and have tried a lot of the suggestions, such as creating lines in a 3D sketch and projecting the geometry to surface, and creating a work plane, and both don't seem to work for me.... I'm trying to cut out a 5.8mmx14mm rectangle out of a cylinder. When I project the geometry to the cylinder's inner surface, I cannot trim the solid in order to extrude.

 

Please help! I've attached the file.

 

Thank you,

Nicole

P.S. I'm using Autodesk Inventor 2014... and I'm new to any type of CAD software; I only know the tools/features I know through online tutorials and playing around myself.

 

Is there some kind of push-pull feature similar to that found in Sketchup Pro so that I can just draw the boundaries of the rectangle on the xy plane (circular plane) of the cylinder and extrude it along the length of the cylinder until it's at a length of 5.8mm?

Welcome to the forum.

I didn't open your part, because I am still running 2012, but have you tried extruding a cut from the inside out?

Can you post an image?

Ohhh no I did not try extruding it from the inside out.. that could work.

 

Here's the image.

I would try to extrude it from the inside out but even when I project my geometry to the surface, I cannot figure out how to trim/modify the lines to extrude it at all.

If you are talking about the notch on the end (shown in the green lines) doing an extruded cut from the end in the 5.8, you could even include the beveled surfaces as well with this sketch.

Yes I need to cut out the shape of a rectangle on the curved surface, only now it doesn't seem to even let me project the lines directly onto the surface. I'm getting this error:

 

"Errors occurred during update

     -invalid curve input for projection curve.

     -projection did not product any output geometry.

     -3D Sketch59: Problems occurred while building this 3D Sketch"

 

How would I extrude a beveled surface? I found this answer via google:

 

"Use the Bevel tool to create a bevel surface around an existing curve or surface edge. This is useful for modeling embossed text and logos.

  1. Pick the curve or curves. Note that you can use surface edges.
    Note

    Any open curves will automatically be closed by a straight line segment.

  2. Choose Surfaces > Planar Surfaces > Bevel.
  3. Do any of the following:
    • Drag the to change the bevel width.
    • Drag the to change the bevel depth.
    • Drag the to change the extrusion depth.
    • Type the bevel width, bevel depth, and extrusion depth separated by spaces to set the values exactly."

 

^^Only I can't even find Planar Surfaces under "Surfaces." Any help?

 

Thanks again,

Nicole

^^ Just kidding I think that's because that was posted for Autodesk Alias, not Autodesk inventor.

I guess my cutting out a rectangle would be similar to adding a gear? Is there a way to do that in Autodesk Inventor 2014?

It would appear to me that you should be able to create a 2D sketch using the end of the part as your sketch plane.

Create the trapisotal shape using the curved edges of the tube and project an extruded cut in the .58

Sketch1 is not constrained.

Is this supposed to be one part or two (or more)?

I recommend that you delete any and all unused sketches.   (many of them are sick)

Have you read this document?

http://home.pct.edu/~jmather/SkillsUSA%20University.pdf

 

 

For those of you not using 2014 - here is the current browser history tree for the part.

(I think we can simplify this a bit.)

(see attached - put your coffee down first   Smiley Wink )

 

I will be back in a little while with a simplified part.

It was really difficutl to determine your design intent from your model construction, but if this doesn't help - post back.

JD Mather,

 

Amazing! Looks great. Is there any way I can now display the dimensions?

 

Many thanks,

 

Nicole

It occurred to me that you might not know how to edit an existing part.

Drag the red End of Part marker to just below ExtrusionSrf1.

Click on the + symbol next to ExtrusionSrf1.

Right click on Sketch1 and select Edit.


Examine

 

Finish sketch and pull down the red EOP to just below Trim1.

Repeat above steps examine the next sketch.

 

Step-by-step you can examine how the geometry was created and edit as needed.

See attached image.
