One problem with trying to treat an infinite line as if it was the same as a regular object is that it can't really be used for input into all the commands as regular curve objects.

For example it would not work to try and extrude an infinite line, or revolve it, etc...

There's some potential for confusion when something looks as if it is a regular object and selects and moves like one, but then when you try to actually use it in other ways the same as other objects it then suddenly stops behaving like the other objects that it appears similar to.

In a 2D only type CAD system I guess you would not have that same kind of problem.

Hi Michael,

It make sense, it could be confusing this way...
Well, it was just a thought.

Hi Eric, yes this what I do also!

I think construction lines are selectable and movable

Yes just click on the little thumbnail that appears at each helpers line release ;)
you can move rotate re orient Divide and project !

Hi Burr,

> I think construction lines are selectable and movable

Yeah they are if you use one of those script methods to make one that stays around after the current command exits.

But it's kind of hacky - they don't have highlights or show in selected colors even though they can be dragged around. It's not really a fully finished off area.

Solidworks allows infinite lines. They can be construction lines or real lines. If they are left as real lines, SW ignores them when using the sketch, say, for extruding. This is confusing so I always convert them to construction lines.
