DSTV NC Data / NC1 Data – general information about profile types and opening blocks

DSTV NC Data / NC1 Data
Overview of the basic profile types and NC processing blocks

DSTV NC data, or NC1 data, has become an integral part of modern steel design,

The only problem is that the templates for manufacturing the components arrive at the manufacturing plants in every conceivable format.

This is why we have developed the DSTV Assistant, to save you the tedious task of converting customer data into DSTV NC data.
The DSTV Assistant works in a matter of seconds and offers practical tools and features to make your day-to-day work easier.

Despite all the automation, it is essential to know the basic standards of the DSTV NC data description, which we have summarized for you on this page and as PDFs for download.

What is DSTV NC?

The DSTV NC format / NC1 format is a universal interface that allows the geometries of steel design parts to be transferred in a standardized manner to NC machines such as drilling and cutting machines, plasma cutters, lasers, etc.

The format is machine-neutral and works with NC machines from a wide range of manufacturers.

The format is therefore the link between CAD/CAM and NC based manufacturing of structural members.

Profile Types

The figure shows an overview of the most common profile types. The profile designations are standardized for NC data according to the following scheme:

I = I-profile
L = L-profile
U = U-profile
B = Plate
RU = Round bar
RO = Round tube
M = Rectangular tube
C = C-profile
T = T-profile
SO = Special profiles

In addition to the abbreviations of the profile types, the axes of the coordinate system, the origin, the defined views and also the transport direction can be seen in the overview.

NC Blocks

The NC file in DSTV or NC1 format is a pure text file that requires very precise formatting and a very precise structure. The good news is that you can safely leave these two points to the DSTV Assistant, you won't have much to do with them.

However, to be able to check the exported file, it is useful to know the respective opening blocks under which the various edits are grouped together.

The drawing of the short beam shows the main types of machining at a glance:

BO = Hole (Bore)
SI = Numbering
AK = External contour
IK = Internal contour
PU = Powder
KO = Mark

The drawing is largely self-explanatory, but it should also be mentioned that the outer contours [AK] consist of several contours, which can be thought of as an abstraction of individual sheets, and that the block holes [BO] summarize all types of holes, including, for example, stepped holes, blind holes, or threaded holes.

Looking for software to help you deal with DSTV NC data on a daily basis?

We have something for you!

With the DSTV Assistant for Creo Elements/Direct and the DSTV Assistant for SOLIDWORKS, we offer two systems that allow you to process templates from virtually any source.

The conversion to DSTV NC data is largely automated, i.e. profiles and machining are automatically identified, you get an overview sorted by profile type and equal parts detection ensures that identical components are grouped together under one position number.
