Any suggestions on extending line to a Rectangle?

[jarredmonday]

Hello all,

 I was conducting a quick lesson at work about the trim/extend commands and enabling the EDGEMODE. It all went well until I was asked if I could extend a line to a rectangle that are not perpendicular to one another. My answer was "NO, a closed polyline cannot be used as an apparent intersection. For it to work the line, which needed to be extended, will have to be perpendicular or have an apparent intersection of the rectangle".

 Is this 100% current or is there something I have missed regarding this?

Thanks,

 Jarred

Sorry. Please move this thread to appropriate forum.

No need to move the thread unless you want it in the AutoCAD Version that you use.

A closed Polyline; say one that makes rectangle 1, cannot be extended as you are asking. This shape will not do that.

And since the Pline is closed there is no Apparent Intersection to extend to.

If the ends of the Polyline do not touch and therefore the shape is not closed then the PLine would extend.

A line can be extended to a closed Polyline as there is an entity for CAD to use.

EDGEMODE set to 1

OSMODE(2048) with Apparent Intersection On.

This should be easy to test just be trying a few scenarios.
