Line table edit 3d polyline Elevation

[aldebaran]

The command table edit 3d polyline elevation is very helpfull .
But sometimes is also helpfull to change distance between points to the same align.
How can I do this with cadtools ?

Sorry, there isn't any command for this in CadTools. Table edit only deals with polyline elevations.

Hello,
about this Table edit 3dpolyline elevation I want to ask something.
How can I split some 3d distances bettwen more points (when I have the first and the last pit in 3d) in the same slope from one command?

If you want to add more vertices to a 3D polyline use CadTools command "Densify". You can also use AutoCAD's "Pedit" command

Thanks for your answer but this is not what I want.
I have to make 3dpolyline exactly over some cadastral lines and these lines not everytime have a 3dpoint to join. Sometimes I have more segments without 3d points and in this case to be sure that I make a 3d surfare I use 3d polylines from the strat till the end of the element. In these cases with Table Edit 2DPolyline Elevation I make manual the densify points.
My question it was if there is a method to keep the shape I give in autocad and to join in 3d 3l3vations the points. I hope you undestand what I want.

For a better example I made a printscreen of the work.

I'm not sure i understand but you can insert points with AutCASD's Pedit. Then use CadTools command "Level out" on the line. Beware, level out smears out the elevation of all points based on the start and end elevations.

As an alternative you can draw a new 3Dpolyline, snapping against the first point (that has elevation) and then snap against any point or line without elevation. Finally you snapp the endpoint of your line against a 3D object with elevation.
Then use "Level out"

Thanks again,
these function is good but I search one function that is not erase the levels I have allready in 3dpoly.
My 3dpoly has many vertices (a lot of vertices and some of them have allready values in Z and some not ... what I want is not to erase de existing levels diferent then 0)

Triangulate your 3DPolylines as breaklines, save to file. Then convert your 2DPolylines to 3DPolylines and then drape them onto the surface (View Surface, Drape polylines)

I think you need to use the level out 3d polyline command only locally to fill the gaps were you don't have z values. just identify the zero height zones and break the polyline , then use the level out command so you don't affect the vertices with real values. in your example: break the 3dpoly at the vertex with z=74.62 and at the vertex with z=74.93 and use the levelout command on that segment. in the end join the 3dpolylines to have a continous one. I guess this is what you want.

I did allready like you sugest me, but there is a good one update of the function  ..... if it's posible.
