That plugin for adding elevation data....?

utiler

Hey guys, can anyone point me in the direction of that plugin that when you pick a point it throws up a dialogue box for user input which results in an elevation point...?

Hi Utiler
Is this the one that you are looking for?

Thanks for chiming in; no not that one. I recall this plugin that I'm looking for added a point in elevation vial a simple input dialogue box from a point chosen on any surface.

Something tells me maybe check on ones by either kirill or Didier Bur. Maybe not.

I really kind of thought it was TIGs but maybe an earlier version you were remembering.

utiler

Thanks Tim, I'll have a look at both those authors scripts; maybe it was TIG's early release...

Cheers,

TIG

My http://sketchucation.com/resources/pluginstore?pln=coordstexttagtoolfromdatum
gives you XY and Z coordinates, BUT you can change its settings to display just XY OR Z, or add a prefix, hide/show units etc...

The older http://sketchucation.com/resources/pluginstore?pln=heighttool_datum just does "Height 1.000m" etc with no display options... The newer tool, with the right settings, is recommended... for your purposes...

Dang, TIG!! That must have been it....!

The description of three lines tools from Chris sound similar too:

"Three tools to help make vertical or normal lines by clicking on a point, then enter the desired line length or elevation."

utiler

Thanks for chiming in, cotty. what I want to do is to pick a point and add elevation data to establish a referred survey data then select them all and create a terrain or even contours. I've attached the data I have been given and my skippy of the perimeter points jointed together. Ran Curviloft and this is the result.

Also tried toposhaper and found that it didn't stick to my perimeter boundaries....

Hello Utiler
The following or a variation of it may do what you want.

Create / import points
Use TIG's Triangulate points to create a mesh (if required)
Go inside the mesh group and use TAK2HATA's Draw Slope Normals to adjust height of each vertex as required[/list][/list]

Thanks Walter, I'll have a go at that!!

I'm just wondering if this is the bets way to create a terrain from survey data provided other than electronic. As per my attachments earlier, I have been given RL's [height date] for a carparking area that I want to model; the data is accurate to all corners so I can easily set out as a profile. Would be good if you guys can give me your comments.

My view of the world - it depends on the size of the carpark, whether you have an undeveloped carpark (ie no kerbs and islands. Also the spacing of the survey spot heights and the level of accuracy that you want to model.

I would have thought that the process that I had described in my previous post would have been the best available to model the pavement. Kerbs and islands etc could then be superimposed using standard SU entities.

Sometimes surveyors include a 3d mesh covering their spot heights. It might be worth checking with them as they may already have this. It would simplify things.

utiler

Thanks Walter, the data came to from the builder as lines of paper so no 3D survey data was available. That's why I wanted to build from scratch....

seasdes

What methodology did you end up using.
Regards

utiler

This is what I've done: feedback/advice is welcome.

import image with survey data; scale to size
use Jim's 'construction line' tool to draw [with end points] a construction line the height above the image the given height distance.
run TIG's 'triangulate points' plugin...
run Fredo's toposhaper' plugin to create terrain....

another option that could be used, if all your points are in the perimeter, would be to just connect them all in a perimeter with lines, then select all the lines and run the Soap Bubble plugin...

or Ferrari one

Thanks fellas, as you can see below in this case they were random points on a site so not bounded my a perimeter line.
Quite often I get spot levels given to me on a hardcopy of a plan so I want a simple way to turn elevation data into a reasonable terrain mesh.
