Just completed an As-built of an existing building and was looking to see if there is a way to adjust the reflector-less shots I took on the building exterior and flatten them out to produce elevation views.
Thank You
Swap Northing with Elevations. There is number of ways of presenting this. What software are you using? You can then treat your as-built as a topo survey, build two surfaces and do comparison using color coded elevation ranges or cut sheet reporting will work too if you just want to present numerical values or both methods if you really want to overload your map with information :-). I tried both methods in Carlson and LDD. I'm sure C3D has similar capabilities...

Yes.
You don't agree with the rest of the suggestions Brad? You can also use sta/offset report (first need to crate HAL at the desired-reference location).
Before you swap northings with elevations, don't forget to rotate the building face so it is east west. The width of your building may suffer otherwise.

I did not read the rest. I have a short attention span.
Thank You everyone for the suggestions. I gave it a go this morning and it looks like this will be a huge time saver.
I am curious as how it is done. In the ascii file you swap the northings with the elevations? and how do you rotate the building? that is after the processing?
I import the data into Terramodel like I do with any other info which means the wall data is on top of each other along the line of the face of the building.
- Copy the data across to the side (to preserve the original data in case of a blunder and to spot check the modified data against the original).
- Pick an alignment along the face of the wall and rotate the data until that alignment is 90å¡00'00". If you do not do this step, your wall will end up shorter in width than the original. Please do not give an architect or engineer a reason to legitimately question your data.
- Swap the northings with the elevations. I have a command to do that but you could export the data to a csv and swap the columns as a work around.
- At this point you will have the wall in a side on view with the northings correlating to the elevations. Place some horizontal lines across the data at even northings to represent even heights and label them. I generally move the data back up next to the original data and put a box around it and label it clearly about what it all represents so clients can measure off the cad file to get their required info.
Fake up some data and have a play. Happy testing.
Cheers Seb, will play around with my data for that. Was curious about the steps to achieve them. Thanks!
If you have floor plans of the building I would recommend you line the elevations up with them and make sure they match along windows etc. You will almost likely see differences given the ability of reflector-less to measure window corners etc accurately.

Have a look at the FlipUp command.

True, missed important step!
Or you could just use modern software...
For example SketchUp; 12D and LisCad ( I think) have functions for Elevation views
