# Drawings lines inside polygons from each vertex

I usually have some idea of how to approach what I want using a few geoprocessing tools, but in this case I don't really know where to start on this one. What I'd like to do is draw a line of a user specified length inside of a polygon that is 90 perpendicular to the side of the polygon. I'll do this by creating vertices along the perimeter of the polygon about 10 ft apart.  I sketched something out to make it a little easier to understand. Like I said I don't know where to start here other than the fact that I do know how to create all the vertices on polygon perimeter.

If it helps what I'm attempting to do is measure a specific distance, let's say like 50ft, from the edge of the parcel inside in order to find the usable portion of land in a parcel to build on. The distance will be the city, county, town, required offset from the parcel boundary.

Any help is appreciated and if there is a better way to do this I'm more than open to trying it.

Thank you

When buffering polygon features, negative buffer distances can be used to create buffers inside the polygon features. Using a negative buffer distance will reduce the polygons' boundaries by the distance specified.

and there is no need to produce hashures since you will have a continuous line

Thanks Dan, I totally forgot about negative buffers. Much appreciated!
