Adjust data based on a more accurate survey
This is an example of a common problem, which is now happening to me. I have a survey done previously with a less accurate method, possibly with GPS, tape, and compass. The fact is that when assembling the total station we realize that the information occupies a deformation.
The point is that if you only take the measure of the external vertices, the adjustment to the internal is crazy.
Let's see how to do it with AutoCAD Civil 3D:
Simple, select Map> tools> rubber sheet
Then, the program requests that the points to be moved and the control points are indicated. The order is first the point that we know is wrong (Base point), Then the point where it should move (Reference point).
When they have all been indicated, it is done enter. Then the program requests the objects that we hope to adjust, all the boundaries of the properties are selected and the Enter is repeated.
Here in this part is where I miss Microstation, because there I could turn off or turn on levels without having to stop the active command. Here it is not possible, the levels that I do not want to select in window should be off.
And there you have it: The more checkpoints, the better. And of course, there must be nodes at the vertices, so that the topological cleanliness is maintained.
It is clear that for a massive job it is not recommended to do it in one stroke, but to do it by block. See how the lower part of properties 4 and 5, because that vertex was not taken, the point did not move, which implies that the lines should be taken or manually modified in case there is no such break.
The tool looks very practical, much more than Microstation has done since tools> warp coordinates.
Hello people.
In which part of the civil 2013 is the command mentioned above ??
Map> tools> rubber sheet
I looked for it in the Planning and Analysis area ... but I can't find it
thanks for replying
