One with both the Features and Trianglesīut what you really need to do is open up a deeper discussion with them to see exactly what they can use, and see if you can provide that. In Canada where the subgrade is not parallel to the finish grade they would need both.Ĥ) Use the InRoads > File > Translators > LandXML Translator and export out a couple XML files:Ĭ.
#How to export svd and svl from powercivil v8i software
To cover all the bases I would give them this:ġ) A MicroStation 3D DGN (or two) of the grading features and triangulation (just display all of the DTM grading Features and the Triangle display on a different level) Some programs can read this 3D graphical data into their software systems and reconstruct the surface, or can extract out what they need.Ģ) An InRoads DTM of the finished grading (just in case they have access to InRoads)ģ) Do the same things as above if you have a subgrade or rough surface however if the rough grade or subgrade is parallel to the finished grade it's not that important and they can make the necessary adjustment for parallel depth control on the grader. Probably the safest way, without knowing anything (and most universal) is to just give them an XML export of the DTM. The specific system they are using will drive the file type that you give them because Terramodel can open a TTM that InRoads can export and then also stair step that data beyond that to create the necessary Machine Control files. They will have to use something like Terramodel or Site Vision Office to take the DTM data and export the files they need (for example: SVD, SVL and CFG) that are taken to the grader. If they want the DTM for AMG (Automated Machine Guidance) or Machine Control work then they will have a special format that they will need the data in that you won't be able to provide directly. Once the Application Add-ins are toggled on, these and other methods are under InRoads > File > Translators. Some of these are part of the InRoads Application Add-ins. And there are Application Add-ins for exports to Leica, Carlson, Topcon and others. For instance, InRoads can export the DTM and ALG for Trimble TSC 2's and TSC 3's. If they want it for staking and expect to upload it to one of their survey Controllers then you can help them by knowing what Controller they have. I would think it would have something to do with the design DTM, not sure.Īny suggestions would be helpful. They are not sure either, the information has been provided to them by others in the past. Would you have any idea what files / type of files I would give them? I have never been asked this before. I have a question from a contractor for me to give them information for grading a project. An InRoads user asked for Mark's thoughts on this question :
