Select multiple polyline when create point

[bunhoc_hh]

When i use Land Destop i can create point-Suface->Along polyline/Contour and select muti polyline. But when use civil 3D i can only select one PL at the time. Did i miss something?

You're trying to compare a paper airplane to modern passenger jet! Civil 3D works on intelligent data allowing surface contour display to quickly changed from intervals of 2' and 10' to intervals of 1' and 5' since they're not actual drawing objects. You can output contours and other intelligent data as drawing objects as drawing objects as needed. I use this often to convert an added contour at the overflow elevation of a drainage area to quickly label it's volume as an example. Land Desktop was replaced decades ago for a reason.

@tombu You right! But for some reason CIVIL 3D can only selection 1 Polyline one by one when interpolate point along that Polyline. But Land can selection mutil Polyline and interpolate point along all polyline. Just say I have 200 PL need interpolate point along PL, in civil 3D that mean 200 click but land can do ít with only 1 click. What i mean is i am doing something wrong here?

For what purpose are you trying to interpolate points along Polylines or even use Polylines in Civil 3D? Civil 3D Surfaces already do that automatically with intelligent figures (not AutoCAD objects) even around curves which cannot even be drawn with AutoCAD objects as a 3D polyline or arc cannot have a curve in it. An accurate surface including turnouts with raised curbs couldn't even be drawn without Civil 3D.

Can you describe what you're trying to do?
