This routine creates 3D contour lines from 3D points. It was written for Autocad 2000, so there's no guarantee it will work for your version. See CTM Lisp Notes.

This routine is helpful if you have overlapping objects that form a closed area and you would like to combine them into one overall closed object. This is like the UNION command but for 2D closed areas. Here’s how: • ECO External Contour of Objects • Select overlapping objects; ! Auguments: 'pt' -???????????????????!!!;;!

I really compliment people to producing solutions available for free or nearly free but the free programs to do triangulation, contours, long sections and cross sections has been around for a long time, the free verison limited number of points, shareware unlimited, I know I downloaded well in excess of ten years ago. I believe what is missing is spageti the ability to take field code data not only create a dtm but also create create a string plan view, including breaklines, then produce long and cross sections. Take a csv level book produce a plan view did that 20+ years ago including strings yeah it had a cost. Ok go and get today a commercial product around $2,500. Virtual dj free download windows 10.

Some may say I am criticizing but I am supporting I spent a significant time of my life as a Civil Software dealer so don't reinvent the wheel make it better spokes and 21' I remember talking to software owner and discussing how many triangles per second could be produced. It was thousands remember 486. ' I believe what is missing is spageti the ability to take field code data not only create a dtm but also create create a string plan view, including breaklines, then produce long and cross sections.' This is the most important thing. I am a C&S engineer.

People do not construct road like what they do in factories. The most a developing or any other country will construct is one expressway or a highway per year. So the speed in the process of triangulation does not have much relevance. The software the designers use should be flexible to build the safest roads and allow the user to manipulate the cross section freely (fully string based) without limiting it to templates. BIGAL, Here's an alternate way to get the set of 3dfaces under a polyline.;; getfencesel by ymg;;;;;; Arguments: en, Linear Entity Name (Polylines, Arc, Ellipse etc.);;; flt, A valid Entity filter Ex: '((0. '3DFACE')) or nil;;;;;; Returns: A Selection Set of Entities touching the selecting entity.;;;;;; Requires: Express Tools;;;; (defun getfencesel (en flt / fe px ss) (acet-ss-zoom-extents (setq ss (ssadd en))) (setq px (* 0.75 (acet-geom-pixel-unit)) fe (acet-list-remove-adjacent-dups (acet-geom-object-point-list en (/ px 2.0))) ss (if flt (ssget '_F' fe flt) (ssget '_F' fe)) ) ). Ymg3, To my mind what is needed is to follow civil3D closely and do what ever enhancements later.

That is also a way of not re-inventing the wheel. As for the centerlines (with or without spirals) were done way back in early 90s. Even the flexible cross section were also done at that time and roads/highways were constructed. Deep blue sea 1999 full movie in hindi free download. At that time the survey was always done on a defined centerline. Now I have to find a way to fix two IPs and move the other with the mouse( perhaps with the help of LeeMac), while my horizontal alignment program runs and give the points at regular intervals. Ymg3's Lawson walk can locate the triangle and get z (with vector dot and cross products). Another snippet can produce the long section base on which the cross sections can be produced.

It appears to me the process is 90% complete (except for the quantities) and summit of MT. Everest is in sight. Regards, Aloy.
