Plotting a buffer zone

[Anonymous]

Hello, 

I was wondering if it is possible to create a "buffer zone" starting from a polyline (A) :

I guess we can consider for example plotting a second polyline (B) that respects a buffer distance (in meters) starting from the initial points of Polyline A.

I didn't manage to find a specific command that achieves this, any idea how it can be done ? 

Thank you a lot!

Sorry, what you are trying to do is unclear to me from the description. Can you post a dwg or image showing visually what you want to achieve?

Offset?

Thanks for answering.

Here's what I'm trying to do basically : 

I'm trying to plot the exact same polyline 20 meters inside the initial one (in the direction indicated by the red arrows). Thus, the new polyline would technically be smaller. That's the idea behind what I mean by a "20 meters buffer"

That looks like a spline. If it's polyline, it is quite complicated.

You can try OFFSET but it may not work.

In paper space you could draw a closed polyline in your viewport that generally encloses your border - and then do a viewport clip to that polyline. If it's all set to a layer that doesn't plot, then what you plot won't show the edges of the border.

Is that closer to what you are looking for?
