trying to create a model from existing polylines (at elevation). I have created a surface, went to definiltion, drawing objects, but there is no "polyline" option there. I must be missing something. How can I create a c3d model from existing polylines? Thanks.
Solved! Go to Solution.
And when adding the polylines as contours, play with the weeding and supplementing factors to make sure the surface is modeled as close to what you want as possible.
I was able to make a surface but when I try to at elevation labels, no figures show up after I drag it across my polylines. Does it make a difference that my plines (that are at elevation) aren't continuous contour lines around the entire drawing?
When you are adding contours to a surface, make sure you toggle on all the minimize flat areas options. Here's why: http://civil3dplus.wordpress.com/2011/08/13/adding
Jeremy: You don't label the polylines, you label the surface. You need to change the style of the surface to display contours and those you label.
I’m encountering the same issue and couldn’t know how to build a contour surface from polylines with elevations
The contour option doesn’t build a contour surface from polylines!
Where might be my mistake?
Make sure you select all of the polylines at once to add as Contour data, make sure the Surface style is set to display the contours.
Thanks you Jeff for the answer,
What might be the issue then?
See attached - you need to set the interval and Display options as well as ensuring you start off with a decent template.
By the way, have you considered a C3D training course or purchasing a book (Mastering Civil 3D 2013 is a good one) and working through the tutorial exercises??
