Using Civil3d and SAGA GIS to create .las file for TGC Designer tools

This workflow has come about due to the potential loss of our community golf training facilities and the need to present options for the relocation of the facilities to a new piece of land.

Initially I mapped out a rough concept for a new course by hand on an aerial photo and then draw it up in CAD using Autodesk Civil3d.

Then I cam across TGC-Designer-Tools that allows you to import surface and design information from Open Street Map into the game “The Golf Club 2019” which has designer functions to model up a golf course.

One of the limitations of the TDC-Designer-Tools at this stage is that you can only import .las files of lidar for the elevation data.

There is however a lot of surface elevation data that is freely available on the internet in other formats. Normally in a post processed format from the original lidar data. In order to use this data in a course or surface data from Civil3d it has to be converted into a .las file format some how.

Fortunately there is an open source GIS program “SAGA GIS” that has just the toolsets you need to import surface data in various formats and convert it into a .las file that can be imported into TGC-Designer using TGC-Designer-Tools as a basis for your design.

What follows is the workflow in progress I have developed to take a design surface from Civil3d and convert it into a .las file for import into TGC-Designer.

1. Download and install SAGA GIS
2. From Civil3d export a DEM file of the design ground surface you want to make into a .las file.



3. Dragged the DEM file into SAGA GIS.


4. Using the PointCloud from Grid Points created a point cloud.


5. View the point cloud data and added a field “Class” for the classification and added 2 for "Ground" for the value of the class







6. Used the Export .las file to export out the .las file.

7. Imported the the .las into TGC designer tools following this tutorial.

Reminder remember to self mapinsert command has double i’s “mapiinsert” and is the best way to put tiff’s in dwgs to xref into other drawings.

Google Style Search for Dwg files

No matter how organised your filing and cad standards are there will always be time spent searching for information that has been detailed before and not added to the system or showing new staff where information is located. In this vain I typed google style search engine for dwg’s in google about a month do so ago I came across a program calling Drawing Searcher by Docupoint

I downloaded the trail and installed and was impressed at the speed of the indexing and searching. The price was very reasonable as well I thought. Once set up on your server you just can direct users to go to an internal webpage and they can search all the documents quickly on all company servers and archives for what ever they are after.

Civil3d Transparent Surface prints Tinn Lines

Reminder to self for some reason when I pdf with a transparent hatch thru Acroplot it prints the Tinn lines in the pdf. For example.



but if I print with the plot command and select this option

it prints without the Tinn lines for example
