feargt Posted September 10, 2009 Share Posted September 10, 2009 Hi, I have a drawing with polylines representing Contours. All the polylines have elevations (10m intervals) and are on the same layer. I need to change the 50m contours to a different layer. So I want to be able to select all polylines on this layer with a elevations 50, 100, 150, 200 .....etc It is over a 200 km2 area I tried using filter but it did not work for me I based the filter on polyline, layer and elevations ie 50, 100 ......etc Has anyone any other ideas how to accomplish this? or what am I doing wrong with the Filter thanks Quote Link to comment Share on other sites More sharing options...
feargt Posted September 10, 2009 Author Share Posted September 10, 2009 thanks to anyone who took time to read the post. I have solved my issue myself using the filter command. If anyone wants the answer I will post it Quote Link to comment Share on other sites More sharing options...
SEANT Posted September 10, 2009 Share Posted September 10, 2009 The filter would look something like this to isolate polys by elevation. Edit: A few minutes too late Quote Link to comment Share on other sites More sharing options...
feargt Posted September 10, 2009 Author Share Posted September 10, 2009 thanks that's exactly what I did, saves me posting the answer now. thanks Quote Link to comment Share on other sites More sharing options...
eldon Posted September 10, 2009 Share Posted September 10, 2009 If you take a Front view, all the polylines are visible with each elevation separately. A visible filter Quote Link to comment Share on other sites More sharing options...
ckaravan Posted December 8, 2016 Share Posted December 8, 2016 I would like to do the same thing. I set up the FILTER the same exact way with my desired input elevations. However, upon clicking "Apply", nothing is selected, and AutoCAD instructs me to select objects. When I attempt to select objects, nothing at all is selected. I have looked at quite a few other posts and can't seem to resolve it. The objects are labeled as 3D Polylines in the properties window. Any ideas? The process used is fairly long, so being able to select all of the major contours (10' increments) and apply them to one layer first would be helpful in streamlining the process.

BIGAL Posted December 9, 2016 Share Posted December 9, 2016 If you want say 10 then 20 then 30 and dont have a huge number of intervals then just sue Polyline and elevation in your fileter keep changing the elevation varaiable. Better way is do a search here its been answered before using a lisp. A post last week wanted colours to change via elevation. Quote Link to comment Share on other sites More sharing options...

Do 3D Polylines have Elevations? Untested, just seems unlikely, as the end points could be at different Z Values. Unlike regular Polylines which are flat, and thus at a single elevation. Off the top of my head, your filter might need to define Z values of end points instead of Elevation, in order to account for 3D Polylines. Using the CHANGE command on a set of non-horizontal 3D Polylines, and changing their elevations to 0, flattened them all out, so I guess they do have Elevations (probably defined by the Z Vertex), but not sure how to apply that information.
