Autocad offset like tool


Badge

My task is to remove under 5m wide parts of polygon, something like that:

In Autocad is command OFFSET. Something similar to buffer.

One possibility to get rid of these parts is (in autocad world) make 2,5 meter offset inside and then 2,5 meter offset outside. Something like that:

But using FME bufferer the result is something like that:

I haven't found a tool, that can do task like Autocad offset does.

How i can easily delete those polygon parts, that are less than 5 m wide?

You can by using two bufferers try a minus 5 meter buffer and then +5 buffer.

Zero stroke offsetter. (no corner rounding, and parallel to Original input borders)

This is answered couple times in this forum.

Find it using this search term.

Hi Gio, can you share this workspace or tool, that does that thing? I do not find this tool from FME toolbox. According this post https://knowledge.safe.com/questions/3382/zerostro... it's seems to be this tool I'm looking for. To make buffer around polygon and avoid round corners.

+5m buffer produces round corners... Look my third picture.

Sure, here you go.

I tried it out first it still works under current FME version.

It is a kinda compleshish workbench i made 2014.

Have fun.
