CAD HELP: 4 lines to 1 box/object how to?

I'm using a simple cad program called delta cad. Whenever I draw something each line is an individual object. For example if I draw a box it is 4 lines, or 4 objects. Not 1 object. This is causing me big problems with my routout cnc program as it does not understand inside/outside offset on a line. A line does not have an inside/outside. But a box (or whatever shape) does. I have autocad 2000 (just don't know it very well). Does AutoCad have a method to put lines into a single object?

Any ideas for me?

Thanks,
Tom

In AutoCAD, use the recangle command or draw a box with the polyline command.

I have a whole bunch of drawings I need to fix. It is a lot more than just simple boxes. It would be a huge task to redraw them

Look in the autocad help file under polyline, it'll tell you specifically how to join single entities in the version you have. Just chain the elements into a single entity.

says you can do it.... don't say how:

"You can join a line, arc, or other polyline to an open polyline if their ends touch. If a line crosses the end of a polyline in a T shape, the objects can't be joined. If two lines meet a polyline in a Y shape, AutoCAD selects one of the lines and joins it to the polyline. Joining also causes an implicit decurve, with AutoCAD discarding the spline information of the original polyline and any polylines being joined to it. Once the joining is completed, you can fit a new spline to the resulting polyline."

now if it just said how.....

I figured it out.... have to use the command line click the edit poly line button>select a line>yes convert to polyline>select the rest of the lines>enter and done Wheew!

Sorry I couldn't get back to you sooner. Use the PEDIT command, which you already figured out.

You can also try the BPOLY command. Just pick a point within the enity you want to bound, and as long as their are no open line segments this will create 1 enity
