I am running carlson civil/survey with autocad 2010, when I import an ascii or csv data file, the point elevations are shown as they are in the file, and as they are in the file when I plot them on the screen, however when I list the point it lists as elevation "zero", when I use the 3DP routine to create polylines it lists the points as elevation "zero" and I have to manually re-ener the correct elevation, If I do a manual screen point entry and screen pick the point and say enter the elevation at 100.00, when I list that point it lists it at elevation "zero",. Has anybody seen this before or does anybody know if I have a setting incorrect,..? any help is greatly appreciated
Never Mind,... figured it out... real Z axis box was unchecked...
thanks
Use POINTS
LIST POINTS
instead of just LIST
this way you can keep the LOCATE ON REAL Z off
When drawing a 3D poly the points MUST be inserted on the z axis.
Now, the easiest way to handle 3d polys is to have your field to finish setup draw a 2D AND a 3D poly when it draws all of your breakline features.
Yes, I have watched people retrace their 3D breaklines node to node. That's fine with me. That's time they are using that I can bypass and get the job done before them. 🙂

Hmmm...I never insert points with Real Z. In fact, when I was first learning Carlson, the Real Z default really messed me up with boundary work.
As far as drawing 3D polylines, you can still do it using Draw/3D Polyline, and if you enter point numbers or range of point numbers, it will use the elevation of the point for the polyline.
I agree with you, setting up your F2F is key to doing it efficiently.
You only need to insert the points on the real 3D axis when doing topos. Rest of the time you go with 2D points.
From WAY back in the days of pin registration graphics, there comes an old saying,"Never draw a line twice.". If F2F is setup correctly and you have thought ahead, you will never need to retrace breaklines.
Any that you missed can be added in the surface edit routine quite easily, but even then you will need the 3d points inserted. Can't draw a 3D poly without 3D points, unless you wish to key in every elevation by hand.

Not to be contradictory - but....
You don't need points on Real Z to topo/contour. I write a csv out, and use that as my selection set. That is a better way, as you can filter out points that you don't want in your tin.
Also, you don't have to key in elevations by hand. Just have to key in the point numbers or range of numbers, and it will draw the 3D polyline with the elevations of the points (points not on Real Z).
Your csv and crd file are on real z.
Using the coordinte file to build your surface is an option that I do use everytime, but you would be surprised at how little surface editing is required when you "double dip" and insert the points on real z AND use the coordinate file. (I use the crd file. I do not convert to csv. That's an extra step that I do not need.)
But then, here's the thing, every operation does what they do per their in house cad standards, and I have yet to see any two exactly the same. The guy that has his package peaked and rweaked the best will win in the shoot out of time management. What ever floats your boat.
