Problems with a half-torus
-
I wonder what's wrong now... It's a long night on shift and started drawing an elbow, it's an exercise really with the general (virtual) notion being to mount the bellmouth up out of the way. So I started fiddling and came up with this:
It gave me a bit of bother trying to draw the support flanges, the result being it's not solid. I'm being told I'll need to manually remove faults. That's my latest problem, I've duplicated and scaled up trying to use the 'Dave R' technique but it doesn't work, SolidSolver unable to fix it. Anyone for some guidance on this one?
-
If you intersect the top face of the flange with the collar you can remove the face you can see in the tube. Then a bit of cleanup of some stray lines and it is a solid.
I can give it to you fixed if you want it.I just noticed it is a group, so edits on the big one won't flow to the small one.
-
Oh fiddle! I should have done it as a component....
I'll try and figure out what you mean Box, I may be back soon... 
-
Strewth! How do you intersect them? There's a trio of choices, with face, with model and with selection, none seem to work.
-
-
Here, I'll give you this gif, and see how you go.
But remember to make it a component this time.Edit:if you are wondering what the first context menu was, it was just the intersect face one, but it was off screen so a moved down and did it again to get it where you could see it.
-
And I thank you once again Box, I did what you said, couldn't see what you could see to understand why it worked bu the result is solid!
-
On your original when you look into the pipe you see a blue face, this it the back side of the top face of the flange, so by intersecting that face you can remove the part blocking your airflow, and then removing the other edge/ring gets rid of an internal face.
-
I knew immediately I'd have internal face when I pulled 'backwards' didn't know to get rid though. I do now
Onwards and upwards, time of home soon for some sleepsssss. Once again, TVM Box. -
Been playing again tonight and seem to have nailed it
Now to get rid of the five star mount and think about how to draw a snap-on clip type system. I've drawn loads of bellmouths of various sizes; it'd be really cool to be able to clip-on clip-off different ones and be able to compare the difference in the torque/power response immediately
-
Superb, Teig! It's neat to watch your progression from the beginning of the thread to now
-
Indeed is is good to see.
Have you thought about a keyhole type slide fitting.
Slide it on and a simple quick release split pin to lock it. -
Or R-pins for more simplicity? Yes, good idea. I've been looking around at plastic snap-clips for ideas but that might be simpler.

I did that myself at the weekend, looked back to the start of the thread that is, my comical first-attempts put a smile on my face

I know the split pin isn't long enough but I can't figure out how to stretch it and it's only for demo.
-
An hour later and I've managed to attach the clips to my model:
Solid Inspector2 is reporting them as solid, SolidSolver is saying I need to select one or other. How would I go about combining the three components into one solid?
-
Assuming the main part is a solid [group it and see its Entity Info...] you'll need to 'merge' the 'clips'
Note:
The 'clip' on the right is not in the same relationship to the pipe as the left 'clip'.
I assume it should be...
Also the back edge of the clips intersect oddly with the pipe-part and their backside radius does not match the pipe's either [see image] - it will mean far more tweaking later on...
Fix those and then with the parts in the same context use 'intersect'.
You should then be able to use SolidInspector/SolidSolver OR add a SectionPlane to look inside and erase the unwanted faces/edges.
-
Even easier than using Intersect with Model would be to make the elbow a solid group, the select all 3 groups, Right Click > Outer Shell to combine them into a solid group.

But, isn't that a Pro only Solids feature ? -

But, isn't that a Pro only Solids feature ?outer shell is in suFree8 and suMake.. it's the only solid tool which is in both free and pro versions.
(it's the same thing as Union in suPro.. though for whatever reason, i find it more reliable than union in pro so i use outer shell.. but really, i can't figure out why suPro includes both OuterShell and Union
)
EDIT
well, apparently there is a difference:http://help.sketchup.com/en/article/1004163

The result of an outer shell is similar to the result of a union. However, the result of an outer shell can only contain external faces while the result of a union can also contain internal geometry.
there's an example image of the difference between the two at that link.. i guess i've never encountered a situation which would require union vs outerShell.
