Thicken problem

I am definitely a newbie. I was hoping someone could help me with the correct way to do this. I need this last thicken command to merge with the vertical sections. Any guidance is greatly appreciated.

    It would appear to be merged, did you find your problem?

    Sorry, wrong terminology. It did merge into the part but I'm talking about the geometry. The thicken command makes the surface go straight out, normal to the face of the lofted surface. This leaves a gap on both ends. I'm trying to figure out how to get the edge of the cone to meet the edge of the outer wall (also the same on the top end).

    Ok, Yea I was messing around with that too for a while..

    Looks like you can't "Use" the thickened edges when looking at the part normal to the sketch plane.

    I was trying to draw a filler triangle on the front plane, then revolve it, it works but you have to fake it by fully dimensioning the triangle filler with a little trig (or eyeball it if your evil >:) ).. But that would not update with the part parametrically, unless you set up some variables.. yadda yadda...

    Honestly you may have to put in a ticket using the feedback tool. To let them know about this "bug / oversight". Not allowing the use of edges/verticies of the thickened face.

    Sorry

    Thanks for looking at it. Makes me feel better that someone with more experience is seeing the same issue. Although, I would have preferred that you had an easy fix for me, even if it made me look dumb ;) I'll play around with it more tomorrow.

    I'd say Replace Face, and Delete Face on the overhang, results in the same thing as michal_1 does I think. Same for the top end.

    Tip: Get your sketches fully defined. Some of your circular edges seem to be concentric, but aren't really. if this wasn't your intention, make sure you constrain things properly so you don't run into trouble later. Also, use the sketch function Use (project/convert) for referencing previous sketches or features.
    This would all be a lot easier using revolve.

    @john_mcclary Use won't work, but Intersection does.

    Top end is more elaborated and I would consider different values for thickening and after my trick, offset the inner cone to desired value.

    The trickiest part of draftsman's craft is to find the right approach. Indeed in this example, it's possible to draw a single sketch and use five features, revolve, two extrude features and two circular patterns (maybe for clarity two sketches).

    Maybe one day I'll be half this good :smiley:

    Honestly? Watch as many Onshape tutorials as you can. Start with these: https://www.onshape.com/learn/learn-cad

    I couldn't get it to work on the top end so I just made the fitting a tad wider and it closed the gap just fine.

    All good tips, but this should really be built using a revolve.
    This is where my inexperience really shines (dims?). Namely, what entity to rotate and how to create it between different planes. I've still got some learning to do.

    Thank you all so much for the insights! I've learned a lot just from this thread. I'll keep poking around in the tutorials and other help videos.
