Join 3D line to 3D polyline

[jpaulsen]

Does anyone have a lisp routine that will join 3d lines into a 3d polyline?

The lines I want to join touch end to end.

Hi

Might want to look at something like -

GeoTools->Polyline Tool set 1 Tools

Have a good one, Mike

ToolPac has a join polyline routine that will work with any combination of 2D lines, 3D lines, 2D polylines, and 3D polylines.

We use a routine called "pedit3d" I cant recall where we bought it from.
We also use geotools occasionally aswell.

Out of interest do any of you ever have an arc drawn on a "3d" ucs and want to join this to a 3d polyline? It appears the only way to get this to work involves faceting the arc into a series of short chord lengths which in a large drawing where this has to be done repeatadly can increase the file size a lot and makes working with/manipulating the arc later a real pain.

In fact I have a feeling a flat normal arc has the same problems if it is joined to a 3d polyline.

Edit : Confirmed, any arc behaves the same way when using pedit3d. Geotools can not join an arc to a 3d polyline.

I usually follow up on my posts but this one slipped through the cracks.

We ended up purchasing "Join 3D Polyline" from GEO Tools. GEO Tools allows you to purchase individual tools which was good for us because we did not want the entire package. It cost about $40 for a company wide license.

Thanks for the confirmation. This may help future readers of this thread.

We purchased Geotools a few years ago and bought the site license which is very good value. One of our surveyors used to work in Saudi with Rakesh who is now the main guy doing their programming I believe - small world.

The join 3d polylines is ok in it, but unfortunately for me it will not join arcs to any 3d polylines.

3D polylines cannot contain arcs. A good routine though, would convert the arc to a series of small chords to mimic a 3d arc.

Just curious, what do you mean by a "3d line"?

[jpaulsen]

A "3D line" as referred to above is a line with different Z values at each end point. AutoCAD just sees it as a line.
