What file type to export linework from Leica Infinity?

I can see the linework in Infinity but I am having trouble exporting it from there in a format that CAD will accept? Any help will be appreciated.

 

This is linework that I drew in the field using the data collector, where it follows each point and draws the lines as you collect the points.

I don't use Infinity much any more, but as I recall it was as simple as windowing everything you want to export, clicking on Export, then choosing DXF or DWG (I preferred DXF) as the export format. Pretty sure it worked consistently.

What CAD program are you trying to import to?

@rover83 I did export it as a .DWG and that seem to work. I imported it to Civil 3D 2022. I recently switched from TBC to Leica Infinity and it is quite the learning curve.

All of my crews have Leica Captivate data collectors and Leica instruments.  We export our jobs (points and linework) to the .DBX folder on a USB drive.  When the file is processed we end up with a .DWG file and an ASCII file.  The .DWG file is coordinately correct and based on whatever system we are working in and the ASCII file drops right in to the .DWG.

I'm working in Carlson SurvCAd with Civil 3D as my CAD platform and my techs prefer to work in straight Civil 3D.  None of us have problems.  It sounds to me that there might be a problem in your file processing procedures.

I export out of infinity and ascii file for the points and then a hexml file. I insert the points into my template and using another new template drawing I import the xml file for the linework. The drawback is the linework all comes in on layer zero but that is my QC process to check each line before using the match layer command to match to the points that come in attached to the linework. When I'm done QC and matching layers I just copy all the linework into the drawing with the points. I will warn you the points and linework are sometimes .001' different anyone know why this happens?

Sounds like software is rounding points to 0.001 and linework to 0.000 maybe?

Which CAD software are you using that imports the HeXML file? I am aware of the DBX importer in MicroSurvey CAD, the CAD software I use (currently), but it's not suitable for my workflows exactly.

I ended up making a custom solution, which involves a script to parse the XML file for the linework information and write this to a concise CSV file for a LISP routine to read and create the linework inside the CAD drawing. I have a lookup table to assign the correct layer to the linework being created based on the description of the line, or name. Also I added ability to create 2D or 3D (or both) linework and the 3D polylines are placed on a separate layer for surface breaklines. I always adjust the survey data prior to importing to CAD, so I wanted something that would draw the lines based on the final positions inside the CAD drawing, and not the coordinates as written in the field. A bit of work to set up, but gives me the control that I was lacking with other tools that try to facilitate the Captivate linework to CAD workflow. Also curious if maybe there exists a slick procedure somewhere that I'm not aware of.

Unless they've added a setting in a more recent version, I never found a way to make sure the linework exports were being rounded in the same way as the points.

I went from TBC to Infinity then back to TBC again. I am thankful that I only had to use Infinity for a couple of years.

I am using Civil 3D. I exported the points as a .DWG and then copied them over to the point file. I did have to flatten the lines and change them to BYLAYER so they would show up on the correct layer. I didn't realize my company had a Feature Coding- Code Table in Infinity that assigned the lines their correct layer. Thanks for all the help! 

 

We usually do break lines as proximity instead of standard because of the .001 difference in points and lines. I wish they could fix this. I could see a couple situations where it would create a problem.

@jacob-wall  Civil 3D, and as long as the drafter (me)knows to connect lines to lines and not lines to point nodes there hasn't been an issue.
