I frequently need to sketch shapes that are totally closed.
If you select the sketch elements, right click and select "Select
chain" then SW selects the entire chain. The problem is that if
there is a small gap between any of the chains then it is very hard
to detect. SW still selects all the entities even though the gap is
there. Gaps in chains in this case is very bad later on.
How can I verify that the chain is actually a closed chain with no
gaps? Is there an automated way?
