I'm trying to make this channel cut to look like the real image below. As you can see the channel cut should join up with the indented circle.
Any help/advice is welcome.
Hey Jake,.. I'm going to post both, a surface (x2) and another which is a cut with a delete/fill/tangent (x3).. but it also uses surface as a cut up to.
..so, here is the x2... btw, I think the others have good ideas as well.. and I just stayed with the original idea of cutting away and blending.. it's ok with the surfacing but bulgy with the delete/fill/tangent... I did not spend much time with either... it could be better.
(also, I have to say,.. I'm not a big fan of "Indent".. interesting feature but it seems to leave slivers or inaccurate edges... I know that is not helping but, for me, the combination of these indent features and thickens.. with surfacing.. becomes a challenge.. (although I like pushing surfacing)... in this model.. I'd suggest staying with the analytical features.. if you can..
Jake,.. from my view,.. this takes some splitting/trimming/deleting/filling but maybe someone has another way... maybe cutting simply cutting and delete with a fill?
Some cuts and fillets... Pretty close. I have only SW2019 available right now.
I will try to write how it's done, but not before Monday as i'm going home now...
Cut the slot first.
add the fillets
cut the hole...
add the two last fillets... done (maybe )
Have a nice weekend.
Or something like that:
Thank you all for the ideas so far. I feel like Paul's may have the closest to the physical part. Krzysztof W.
we need the main trough part to be larger than the indented circle. That is the right idea though.
If we were able to sort of use this boundary surface (below) it could work. I'm not very great with surfacing though, so maybe someone can help?
RED = MATERIAL TO ADD
BLUE = MATERIAL TO SUBTRACT
We need to get the RED material to follow the trough curve (see below). Hopefully that makes sense.
..and, here is the x3..
..I'll add a modified surface version or x2b... this gets closer to a smooth transition by adding curves to help the flow of the fill surface..
I think this is close enough! Awesome Paul! I just changed the fillet to a smaller radius and it looks to me like the real thing. That delete face & fill worked wonders there.
I like this idea Ned. I just need the trough to be wider than the circle (this is the bottom view)
Like this? 2 radii only.
Or like this 3 radii
Yes there are 3 fillets, but the third fillet would be smaller. This looks good too!
This was the closest I've gotten. Based on everyone else's ideas, I believe the only possible way to add the fillet to the bottom is to actually split the face-up. Otherwise, there are issues with the fillet and the tangent propagation.
EDIT: Made some changes after noticing that the fillets weren't symmetrical. After making the changes, the results did vary slightly but can't be positive unless we know whether the curved cut is circular or more elliptical. I decided to do a more elliptical cut.
I liked everyone's idea but unless we stated that the circle must be smaller than the trough, then it would just be a guess that size of the circle I picked was tangent to the outside fillet. If it was any smaller, I think we'd need to use surfaces to generate the fillets.
What should be the difference between slot width and the circle diameter?
This is what I measured:
Blue trough dim = 23.50 mm
Red circle dim = 18.10 mm
Retrieving data ...
