how to remove multiple Vertex in DXF files

I have attached a DXF file. I have a dxf file which is a logo and I would like to use this file for plasma cutting on a round plate. however this file has millions of points (vertex) which creates trouble making this cut through the plasma cutting. How can I make is smother or how can I remove multiple points from this file. ?

You can put PolyLines on a Diet with PLDIET.lsp with its PLD command, available >here<.  It reduced the larger Polyline from 1210 vertices to 370 by using 0.2 units as the maximum length to straighten, and accepting defaults for the other options.  You will need to experiment with the trade-off between reduced number of vertices and fidelity to the original shape.

[P.S.  It can't be used directly on the .DXF file, but only in AutoCAD in the .DWG file as you posted.]

what are the steps to use the lsp file in autocad and to use the command pldiet?

Save the PLDIET.lsp file somewhere [can be anywhere, but preferably at some location that is in the Support File Search Path list in the Files tab in the OPTIONS dialog box].  In a drawing, use APPLOAD and navigate to where you put it, select and Load it.  The command name is just PLD [as it will inform you when you Load it].

You can only load a lisp file if you are using a full autocad, in AutoCAD LT you cannot load lisp files. If you have a license for a full autocad, you should also have access to the AutoCAD MAP 3D software, there is a commando MAPCLEAN in AutoCAD MAP 3D that can do exactly what you want.

There is also a "weed" lisp routine going around. Again if you have full AutoCAD you can load that in with the _APPLOAD command and run the weed command.

WEED works only with 3DPolylines and the older "heavy" 2D Polylines [which the Properties palette calls "2D Polylines"], not the newer "lightweight" 2D LWPolylines [which the Properties palette calls just "Polylines"].  That's why I wrote PLDIET.lsp.

 

You can get the 2nd edition WEED2 >here<, if you need that.
