gsf file

Did you add it to the Project (.rwk) File?

How do you add it to project file? Do you need to create the rwk file even for use of the site modeler?

Well, yes & no, lol. Technically, you don't have to create a .rwk file, but you'll quickly learn it's a must.

Um, you said you downloaded the data set. Are you doing one of the online training modules? If so, there should be a .rwk file already created. From the InRoads Explorer, click File > Open, and navigate to where you saved the data files, and open the appropriate .rwk file. Sometimes they put it in a separate RWK folder, but not necessarily. After you open the file, click Cancel on the File Open dialog. You don't really see the file open, and nothing visible really happens, but it opens. Then, do the same thing to open the respective .gsf file.

Next, to add the .gsf file to the .rwk file, click File > Save As from the InRoads Explorer and click the Options button at the bottom-right of the Save As dialog box and click on the Site Modeler tab. You should see your .gsf file listed. Enable the Add check-box next to the file and click OK and then save the .rwk file. Click YES when prompted to over-ride the existing .rwk file.

I asked if you were doing the training module because that's what it sounds like. If not, I apologize for being presumptuous, and just post back and I'm sure someone will be willing to help you (including myself). However, if so, then I highly, HIGHLY recommend you complete the InRoads Fundamentals course first. That one goes in to detail about the .rwk file, and what it's for and what it does, etc., and how to set up your project defaults for all of the various files (i.e. dtm, ird, etc.). Although that module is geared somewhat more towards roadway projects, it will give you some better introductory knowledge and you'll definitely have a better understanding as you go through the Site Modeler modules. In fact, the Site Modeler modules can be somewhat confusing in a few spots - particularly if you're just learning - and just aren't as in-depth as some of the others. Again, I highly recommend you complete the InRoads Fundamentals course first, you'll be glad you did.    

Thanks. I actually had taken the InRoads Roadway course couple weeks ago. now I'd like to use it for design. But it seems that the site modeler is totally different than roadways. I am trying to find a tutorial on site modeler, but I may need to go back and learn the basics of setting up preferences for both roadway and site modeler first.

Roadway design works fine for me. To design the site and tie to the proposed road is my next task.

The site modeler is essentially the site modeler from GEOPAK, so a tutorial for GEOPAK can be used as long as it is on the site modeler.
