Map Clean Up Tools

I'm not sure where these stand on your development list, but I believe these would be a great addition to MapWorks.

Your polyline weeding algorithm is lightning fast - congratulations.

Look at AutoCAD Map for examples but I think the following would be useful:

    Points - group and average the elevation within a radius. Your grid averaging may already do this but I have not been able to get it to work with a large file.
    Break lines/polylines at intersctions
    Delete duplicates
    Delete short lines
    Connect end points of lines within a specified radius
    Delete closed polylines by area < then

We have a lot of new stuff complete for the new version, but we're bogged down right now in porting all the old code to a new code approach. It's hard to explain but some of the stuff we did back in 2007 needs work.

You mean plain point objects or Cogo Points (Blocks/Attr)? We currently have some point cluster tools in the points section.

This IntersectBreakAll tool is done for the new version. We needed it for parcel preparation because a collection of closed polylines with hundreds of duplicate segments is NOT the way to go.

I assumed that was covered by now, at least in ACAD.

I think a select figures by length range would be best, so you could also move them to another layer (see below).

We need to work on a new joiner that has a tolerance value but also smart connect (for example when a Tee is encountered).

We currently have a select by area tool in ToolPac which could be brought over. I think the select by approach is best, then you can delete or move to another layer, etc.

BTW, in the future a new post for each topic would be best, it's hard to maintain a trail of replies when multiple subjects exist in one post like this.

Convert zero length lines to points needs to be in there somewhere.

A new tool (Parcels Breakup All) was added to 6.0 that falls into this category.
