Hello, all.

Has anyone has any experience with MATWEB's (http://www.matweb.com) new
Soliworks material library feature? They say that for $50/year you can
have full iste access and can download material properties in Solworks
material libray format.

I tried the sample libray and it worked, at least.

Wher's everybody else get their properties sets? Anyone fdevoted to
stricty putting in what you need "by hand"?

We created our own custom material list. I used some of the info from
www.matweb.com for a few of the materials we use. I didn't think it was a
big deal to manually enter the info. You do it once and your done. Put it on
the network and share it with all machines.

I decided to go with a custom material list because I needed the name of the
materials to be a specific format so that when I open a sheetmetal part in
SigmaNEST, our laser cutting software, the name matches the format that I
need to import it correctly.

Thanks, Rich.

I've tried a couple, but it's interesting - not all the variables are
always there, and I can't seem to be able to add new/missing ones, or
to find a list of variable names (i.e., EX, ALPX, etc).

It's never easy...

Yeah, I know what you mean. Some of the variables need to be converted to. I
haven't added any new materials in a while, but I probably will be very
soon. Our company bought a few other companies over the last six months and
we're revamping our wood products line, so we'll be adding a bunch of new
woods and some other sheetmetal properties to out list.

What flabbergasted me is the lack of a real editor. I use COSMOSWorks,
which uses temperature dependent materials properties (and perhaps time
dependent as well), and that's in a sldmat file as well. But no real
editor, no documenation as to allowed material propeirs & names (at
least that I've found). Ya know, it's areas like this (and my nags on
the BOM) where the rubber meets the road, and what happens? Incomplete
stuff that requires you to be a VBA wizard to work around.

I was poking around in the sldmat file in 2005. This is what I found:

The capital letters such as EX, NUXY, etc. refer to standard material
property nomeclature in Cosmos/M. If you can get a hold of the Cosmos/M
documentation you will find all of the material property designators.
This documentation can typically be downloaded from SRAC.com. Whether
CosmosWorks will support a particular designator is something you will
have to determine by reading the CW docs or by testing. The units used
above are MKS units so IPS units will have to be converted.

The sldmat file itself appears to be in XML format. It resides in
\lang\english\sldmaterials with the sldmat extension. Any file with the
sldmat extension will appear in the materials list box if it is in that
directory. TOOLS/OPTIONS/SYSTEM/FILE LOCATIONS/MATERIALS can be pointed
to multiple directories with sldmat databases as an alternative to the
above directory.

My guess is that the <material> tag and the <physicalproperties> tag
are all that are needed to add a material to SW. The <material> tag has
two parameters, name="" and matid = "". It would appear that the matid
must be sequential.

I don't know if Access or Excel have the ability to read in an XML file
and make sense of it, but if they did this would be a convenient way to
manage your properties.

This API example could also be useful:
Get Material Database and XML Schema File Names Example (VB)

You da man, TOP. For some reason I thought the sldmat file was binary-
I thought I did a quickview...
Still, what is up with the XML stuff lately? Why not just read flat
text, that's just about wat you're doing anyway...

Thanks,

Tom

I supposed because it creates a standard format for transfering data.
Most of your MSoft applications like Excel, Word and Access can read
and write these things. If SW provided the Schema I think Excel could
be used to manage XML data.

OK, here is some flat text. Pretty handy.

Holey moley! I'll be a while just wading thru all that!

Thanks!

You can use internet explorer to read the sldmat file and look at it in
native xml format. Also you can use visual studio .NET to extract the
schema for the xml file.

I used gawk to massage that list a little and then sucked it into
access. There is a little inconsistency in the format of one of the
fields, but I could probably wring it out into a sldmat file with a
little more work. And as always with a list like this you have to check
out the data before you use it for design purposes.

Ok. I was feeling ambitious and wrote a solidworks materials gizmo in
LabVIEW to manipulate these files. It reads sldmat files and writes
flat csv files, or vice versa.

In any event I sucked the reference file into Excel and parsed it to
create categories and such. You can download a copy at
http://www.dubea.org/longmaterials.csv

Then I pushed it through my converter and created a sldmat file. You
can download it at http://www.dubea.org/longmaterials.sldmat

Be forewarned it takes a few moments to load up.

Have fun.

I had a problem loading it into 2004.

dubea.sldmat
The attribute 'matid' on this element is not defined in the DTD/Schema.
line 9, column 38

I used a text editor to remove the offending property. The sldmat file
then loaded. However 2004 showed the modulus for aluminum to be
1.221e+007 N/m^2 no matter which system of units was set for the
documents. This number is appropriate for psi, not metric. Apparently
2004 converts the mks units in the sldmat file to ips but appends mks
units regardless of the units that are set in the model.

I'm running into all sorts of issues regarding the units in the
library. Also the format evidently has changed as well because it
loaded just fine in 2005 SP3

Thanks for the feedback.

I mentioned this because too many people will just load up the
material library and blindly use it for mass properties or in
CosmosExpress without ever checking to see that it was correct and
giving the right answers. I don't think that you will find in the help
any documentation whatsoever on the format of the sldmat file, changes
between different revisions, methods of calculating conversions between
units or the source of the data and whether it is average, maximums or
minimum properties. For plastics you don't know at what temperature the
properties are valid. So the user is responsible for checking anything
that is used.

Geez did I screw this one up. Boy. I'll repost it when I've finished
fixing it.

My apologies!

I've uploaded new copies. These seem to correlate well with the
original values.

The values for thermal conductivity and specific heat are zeroed out
because they weren't in the original list.

Please check these values before you use them. I cannot be
responsible for the validity of the data. All I've done is reformat
them and parse them into the proper file schema.

The download links are:

http://www.dubea.org/longmaterials.csv

and

http://www.dubea.org/longmaterials.sldmat

It might make some sense to break this up into separate files for the
separate categories. It would load faster that way.

If you want to update the values, please so, but I would GREATLY
appreciate if you would e-mail me a copy.

My e-mail address is chris.dubea at gmail dot com

Cheers,

Hi, this thread is very old, but I would like to request the sldmat file! I am looking for SAE materials like SAE 1010 but a big database would be great. If somebody has something, please share :D

Hi again. I emailed Chris, and he kindly sent me the file longmaterials.sldmat. I'll copy the email here:

/Holy carp.

So yeah, 17 years in the past. The file works in solidworks 2022 no problem, and it has a lot of materials.
