Grouped elements arenot chains are they?
I have a real dislike for the chain tool in ustn. It would be nice to be able to select all the elements you want to join into chains and then join them vs. having to pick each element one at a time. The Auto mode does not give enough control such as when you want to stop the chain at a certain point. If the grouping method you mentioned can creaate a chain that would be a great soluton. Our civil design software requires chains, not grouped elements, to work with.
I'm trying to find a V8 version of a mdl app I had back in V7. It was called Joins.ma and had the ability to join line strings. I used it to join line strings that were on the same level to form a complex chain. I used this rather than the create complex chain command as this mdl required no user interaction.
it had these command line swtches
If nobody knows of a V8 version can someone suggest a way to join the line strings.
