Moving points to associated elevation.

Anonymous
Not applicable

I am working on a Topographical Survey where all the points have moved from their surveyed elevation to '0.00'. I assume this has happened during the action of being processed by the survey team. In the past I have gotten round this problem by making my surfaces from the text as a 'Drawing Object' after moving all required text to elevation. The issue here is that this never moves the associated survey point with the text (I would not expect it to as it offers too much opportunity for error) however on this project I have had a request from another company to reinstate the 'Z' values for the points as they will require these for his Revit model. As I have never used Revit before so I explained that I would usually use the text and he assured me that he can't do that.

To that end, I am trying to find a way of moving all points back to their associated elevations. Possibly a command that will move them according to their closest text object. The topo contains around 4000 points so it would be massively beneficial to not have to move them all individually!

Any thoughts or advice would be greatly appreciated.

Chris,

 

I'm not quite following you. OK, so you use Text-to-Elevation to give your AutoCAD Points a Z. From there what do you need to do?

OK. I'm guessing that the points are either a text "+" sign or block and a piece of text.

 

First and simplest method would be to request an ASCII point file from your Surveyors and import them a Cogo Points at elevation.

 

If all the text is offset from the point mark the same ammount. You can move the text insertions to the points in one Move command. To actually move whatever you have as a point mark in the drawing to the elevation. You would have to use a "Point Block" and add the elevations as attributes. Then you could use Convert Land Desktop Points to create Cogo Points at elevation.

 

If you can post a drawing with a couple of those points in it. That would help.

I agree with @AllenJessup's comment that if you CAN get the original survey data it would be a HUGE time-saver. If not, then it should be a relatively straightforward thing to write up some LISP code to search for each block instance, find the nearest test string and perform a simple MOVE in the Z plane. If someone here can't do it then you might get a faster response and much better bandwidth posting this over in the AutoCAD Customization / LISP forum >>HERE<<

Possibly a command that will move them according to their closest text object.

 

Request the full working 30-day evaluation of DotSoft's C3DTools and use it's Point > Convert Text tool (dialog below).

Tell it the text is Elevation (1) and the other is Node, then select all your geometry (possibly changing the max distance between them), the results are multiple AeccCogo Points.  For the curious, what Elevation (2) is, it's when the elevation text is broken into two objects with the point between them acting as a decimal, like "123 + 45",

@Anonymous, It looks like your are getting some good help her. I'm sorry that I cannot add anything.

 

FYI - This is a minor issue regarding net etiquette:

Your attachment is a Word file containing two images.

You might want to consider a different format.

 

Word files can contain viruses and malicious macros. Most browsers open attached word files in protected mode or read only mode as a precaution. Even then, many people will not open Word files from unknown sources. (I am pretty trusting of anyone in these forums, so I opened it.) 

 

Cheers,

Chris Stevens

Good Morning all,

 

Thank you for the responses. I will give them a try and credit the solution once I have figured it out.

 

Apologies for the 'Word Document' infringement (!) I was unaware that these types of documents would be considered 'controversial'.

 

Kind Regards,

Chris Bowles

No, the text-to-elevation command only moves the text to the elevation. The points that are associated with that text stay at a 'Z' value of 0.00.
