Description

This command is useful to optimize splines, convert them to polylines. It’s very useful to use this program before extruding contours into a solid. It combines commands _Join, _Boundary, _Overkill, _Splined it and many additions.

 

If CNC milling machines are used in production, then you probably have to prepare the contours of the parts before exporting to the CAM program. It's not enough to take flat images with 3D solids. You need to remove the overlays and intersections of the lines, convert the splines to arcs, close the contours in the polyline, assign the correct layers according to the type of processing. All this work can be done with the regular means of AutoCAD. But it's long and you cannot notice mistakes.

 

Features of the program

  • Searches for the largest outside loop in a set of intersecting lines and curves.
  • Allows the lines to intersect. All the tails will be cut off.
  • Closes the contours inside the outer, nested into each other. And distributes them on layers - for external and internal milling.
  • It can create several contours at once by one command call.
  • It connects small breaks in the contour.
  • Correct slightly squinting horizontal and vertical.
  • Converts splines and ellipses in a line and an arc with a given tolerance (the maximum deviation from the original curve).
  • Projects 3d splines and 2d and 3d polylines onto the XY plane to convert to normal polylines.
  • Works with the object 2d-polylines, which occurs when the text is exploded using the TXTEXP command.
  • Restores the circles from ellipses and splines when the cylinder was projected crookedly (hole in the solid).
  • Cleans rubbish: small pieces, dots, layers of lines on each other or located too close (similar to the cleaning command Overkill).
  • Gluing tiny trimming lines into full lines and arcs.
  • Is able to replace the chain of small lines with arcs, and vice versa, too straight arcs - by straight lines.
  • Combines a line, broken into segments into one whole. This optimizes the number of segments.
  • Turns the arcs with NormalZ = -1. These are the same arcs that FlatShot leaves and because of which it is impossible to extrude solid, nor to process it on the CNC.
  • Spreads the resulting contours by layers. If inside contours are detected, the program can write the milling depth in the layer name.
  • Identifies the contours of pockets that cannot be traversed by a given cutter at a time and placed in a separate layer.
  • Calls the Inside Corner command to form the milling cutter into the corner. This option can be enabled separately for external and for internal loops.
  • It filters the selected lines, ignoring the invisible and auxiliary layers and the type of lines.
  • Works in the UCS. All objects will be projected onto the XY plane of the current UCS.
  • Works within specified, configurable tolerance.
  • You can enable and disable layer management.
  • You can use layers from a template file.

 

This command is called inside the NC_Prepare (NCP) and Overall Dimensions (DimOverall) commands. It is a part of the A>V>C> Pro package. Previously published in the CNC_Prepare  plugin.

Trial Description

Download the plugin in the AVC_Chop_nnnn_nn.7z archive. You can use the program for free, but from time to time the activation window will appear. If you donate $15, you can disable this window.

    Plugin works as described. Very useful.

    Also, the developer is resposive with any questions and very helpful.
