When working with sketches, sometimes there is a right-click option to select chain or select tangency. Do any of you know what determines when/why those options appear and when they don't?
I think Select Tangency is for selecting model edges. Along with Select Loop - the model edge equivalent of Select Chain.
If I have to check two edges are tangent the presence of Select Tangency in the menu is enough to tell me so.
ie - it only appears when you have tangency.
Perhaps I'm thinking of Select Chain. Kind of hard to remember when I can't make it appear.
It only works on solid-line chains, not construction lines.
Sometimes not on solid-line chains, either.
Gotcha, I hadn't experienced that. At least not yet.

Not true any more. don't recall when they added construction lines to the select chain, but it was a few years ago.
requirement for select chain;
I didn't think of that. We're on 2017 here.
I've found myself wanting that ability quite often.
If nothing is connected to a line or arc's endpoint to establish the condition of a chain, then Select Chain will not be offered to click.
I find this problematic when importing poor quality DWG as sketch, particularly as opposed to operating upon a sketch which I've created in SWx. Poor quality CAD sources are woefully common, such as endpoints not shared and other gap / overlap problems.
In this case, I've gone through and created an extrusion from the chain, so I know it is a continuous profile. I had to select each one by hand.
Agreed, sketches can be very problematic. Converted sketches are almost always a headache.
You may have a continuous profile, but duplicated, overlapping entities. Earlier versions of SW weren't forgiving of this and would not extrude with duplicated entities, but I've noticed later versions (since v2017 or v2018?) will allow it. However, even the new versions won't always/properly select a chain with duplicated entities. In cases like this, I'll wander through the "chain" and delete stuff until I delete something that doesn't disappear (duplication finder method for a caveman).
Good point, I'll check to see if I'm selecting duplicated elements.
You were right, all of the elements are duplicated. I still don't get the Select Loop option, though.
I have another workflow idea, with potential usefulness depending on repetition or not, now that I see a sample of context image.
Take selected conjoined segments and replace them with a Fit Spline. This would also remove vertices along the path, with any corresponding edges in extrusions or such - in case those matter to you. End result, when you need to select it in future: it is one entity to select, or at very least a smaller pile of entities to select.
If the geometry includes branches, the chain stops. (There is no select chain option.)
Are there branches in the drawing?
No branches, but it does have multiple closed loops. Could this be the problem?
