closed offset polyline

[Bart1979]

Does anyone know of a quick way to create a closed offset polyline?

I have to make a detection plan for a new cable, but the future cabletrace has to be detected with a perimeter of 1 metre ( variable; per project offset can be set at 1 metre or more / less )on both sides.
however, offset will not work here since there's a lot of traces to be detected.

i really need the ends to be closed so I can hatch them easily when detection has took place

anyone know of a CMD or LSP that can do this?

kind regards, and thanx in advance

I'm not sure if the exact solution is here, but this is a start.
And I bet LeeMac already has the rest of the tools to put a finished product together.

hello,

I figured out BricsCAD ( and AutoCAD ) has half the solution already baked in. It's called MLINE. MLSTYLE can be used to create custom MLINE styles including offset width, linetype and color and start / endcaps.
Brilliant so far. But this has me retrace al my polylines in order to have the MLINE to be drawn.
When MLINE would work on already drawn polylines, just by selecting them, it would take off a lot of work. Besides, why draw something, you've drawn before???
anyone?

( PS, I Know MLINE doesnt make polylines, but EXPLODE and PLJOIN cmd's will do the trick.

kind regards,

Bart

AutoCAD's MLine was half-baked when R13 came out lst century -- and has never been updated. dunno about BricsCAD, but IIRC Draftsight has a Rich Line command that works similarly to MLine, but generates Plines as output.

Why they couldn't make MLine work like it's predecessor DLINE.LSP which worked with arc's as well I'll never understand.
