Default SEMROC Body Tube Database File for RockSim 9

Everyone,

Over the last few days, an attempt has been made to create a complete set of component database files (CSV files) for SEMROC items. Small sections of this work has already been posted, but as we check our work, we're finding measurement precision errors in the entries. The problem is easy to correct, but it is equally easy to slip through the cracks.

The new file, attached below, is the full set of body tubes as offered on the SEMROC website. It is being put here for review, so wait before we announce an "all clear" to install it.

Addendum: OK, so much for my ability to pick the right file to upload. I've attached the Semroc BTDATA.CSV file below.
Attached Files
File Type: csv NCDATA_Semroc.csv (27.4 KB, 383 views)

I hadn't run across any errors in the previously posted files yet but I've only used the components in two designs so far that I'm updating for BARCLONE. I kept a complete back up of my v9 install and it's easy enough to load the original component files back in. That's one thing I really like about RockSim is the ease in moving data in and out of the databases by editing the csv files.

Craig, a big thanks to you and Bill for you efforts with producing these component files!

Default Correction to earlier post

The BTDATA file is now attached to my earlier post, along with the NCDATA file. These contain only those components from the Semroc website which can be drawn with the 'wizards'. There are almost as many that cannot be drawn that way, and for those, we'll have to generate RKT files later.

Here are the BHDATA (bulkhead) and TCDATA (tube coupler) data files that have been checked and verified for decimal precision.

Craig - please give these the once over and make sure the numeric precision looks ok. I used the technique you suggested in Microsoft Excel to ensure 3 decimal precision on all numeric fields.

Transition file may take a day or so to complete. I actually took a break from parts and was working on my first 2009 design. I hope to post both by the weekend.

Thanks for combining the nose cone and body tube parts into master files!

... Bill

I thought so. The problem with rocsim is that it is just too expensive! I would gladly pay $50 for designer software but $120+ is much too high.
