Explanation of Terminology - Tangent Continuous
Explanation of Terminology - Tangent Continuous
(OP)
I am increasingly exasperated by the term "tangent continous" used to describe an error in a swept protrustion and the inability to locate the definition anywhere within SE V19's help section. What do I need to correct on my sketches to eliminate this error? All of my sketches are connected as far as I can make them. I have a simple 90 degree turn located in one sketch plane and SE refuses to sweep the profile around this turn.
Any help would be appreciated.

RE: Explanation of Terminology - Tangent Continuous
If it works, it means that your cross section is too big and self-intersects at some point along the sweep.
If it still doesn't work, make sure you have a tangency (symbol=circle) at each endpoints in your path sketch. Especially if you are using multiple paths or sections.
Also, if your path is built using more than one sketch. Combine your path into one entity use the derived curve command and make sure you select that feature as your path.

RE: Explanation of Terminology - Tangent Continuous
I have a simple path in one plane that makes a 90 degree turn. I have a second sketch that makes a compound angle from the first sketch. I have connected the sketches using the Blue Dot command and SE tells me that the distance between the two sketches is 0.0000 inches. I can sweep the single planar path from either end using a plane normal to the curve, but SE won't make the compound corner and keeps telling me the first path is not tangent continuous (whatever that means). A derived curve radically alters the path sketches into a different shape that is not what I need.

RE: Explanation of Terminology - Tangent Continuous
as Ferd already did point out *all* segments your path is
constructed of must be not only connected but must show
the tangency symbol. In other words make each line tangent
to the next. A 90 degree (sharp) corner will not work
with a protrusion (self intersecting) unless you profile
is indefinitly small

the name should have been Fred, I apologize for that typo
The only thing to get a sharp corner is IMHO to cheat a bit.
For I don't know wahr profile you try to sweep I've put
a small sample here
Sweep
You have to unsuppress the features
BTW: when you get "... coincident faces .." as error for any sweep
then a curve on the path is too sharp for the profile to sweep around

I just discovered a small misalignment so the corner was
not accurat. The file has been replaced, so the above link
is still valid

RE: Explanation of Terminology - Tangent Continuous
did you unsuppress both protrusions and the cutout?

Thanks to all of you guys for your help. I think I have a work around on the project that avoids the compound miter afterall.
RE: Explanation of Terminology - Tangent Continuous
when a feature fails it either shows a red exclamation mark
or a grey arrow. The crossed circle just tells that this
feature is currently 'out of service'

I am building a section of mitered pipes that form a compound angle.

Isn't it possible to use the 'Frame' feature for for this?
