Lessons from a Simple Task - Using the Pause Command in a Batch File


Just today, I made myself work a lot harder than was ever necessary.  It started with a little bit of overconfidence, transitioned to about thirty minutes of frustration and swearing, and ended with success and a self deprecating laugh.

It started when I need to create a sample script to defragment an Autodesk Vault database.

How hard can it be, after all?  It's a short script.  It's only a few lines long anyway!

First, I grab the sample script from the Vault Help system.  You can find that in the defragment section at this link.

So now I have my command!

 Connectivity.ADMSConsole.exe -Odefragmentvault -NVault -VUAdministrator -VPadmin -S

This will fire up the command, but I still need to add my path information as well as my Vault name, I also need to add my administrator username and password.

REM - This Script Defrags the VAult Database
REM - Switch Legend
REM - Odefragmentvault ==> Command to defrag database
REM - -N Designates Vault name (this will vary machine to machine)
REM - -VU Vault user (must have administrator rights)
REM - -VP Vault password
REM - -S runs the script silently

D:\Program Files\Autodesk\ADMS Professional 2015\ADMS Console\Connectivity.ADMSConsole.exe -Odefragmentvault -NArduinna -VUadministrator -VP -S

IISRESET

So a little cutting and pasting I have the script I need.

Now, time for the test.

I run it once, it flashes on the screen and immediately disappears.

I check for syntax error, and I do find one.  Which I quickly fix.

But the script doesn't run.

I check my vault name, my administrator name.  My vault doesn't even have a password!

And for those of you with your mouse key on the comment button... I know it's bad practice not to have a password for the administrator!  But this is a personal Vault, on my laptop, which only I access.  So Thpppt! 

Finally, I have an idea.  One that I should have had a lot earlier than I did..

I add the word Pause at the end of my script.  So the script won't disappear when it finishes.

Let's take a second and think about this.

As soon as I run the script.  I see two words immediately. "Not Recognized".

I say phrases commonly found in garages, aircraft hangars, and factories everywhere.

The double quotes at the each end of the path are missing!

Wait! What? This is the problem! 
I look at my reflection in my computer screen.  "You Idiot!"  I shout, channeling my inner Ren.

It felt a little like this. 
I should have known!  When running a command with spaces in it, you have to put the command inside of quotes.

If you don't , the script reaches the first space it sees, and tries to execute that.

So my batch file got to D:\Programs, tried to run that, and didn't know what to do.

In order to fix the script, I had to change the command line to look like what is below:

"D:\Program Files\Autodesk\ADMS Professional 2015\ADMS Console\Connectivity.ADMSConsole.exe" -Odefragmentvault -NArduinna -VUadministrator -VP -S

The quotes (in red) placed before D:\Program and after ADMSConsole.exe make all the difference in the world.

One more shot, and it runs fine!

So the final script looks like this.

REM - This Script Defrags the Vault Database
REM - Switch Legend
REM - Odefragmentvault ==> Command to defrag database
REM - -N Designates Vault name (this will vary machine to machine)
REM - -VU Vault user (must have administrator rights)
REM - -VP Vault password
REM - -S runs the script silently

"D:\Program Files\Autodesk\ADMS Professional 2015\ADMS Console

\Connectivity.ADMSConsole.exe" -Odefragmentvault -NArduinna -VUadministrator -VP -S

IISRESET

And that's it! It's ready to go.

Ultimately, what did I take a way from this one?
  • Use the PAUSE command to help analyze scripts.  Because it was a short script, I figured if I studied it, I could find my error.  But I didn't see the missing quotes. I missed the trees because of the forest, if you will. By adding the PAUSE command, I found my error in seconds.  Literally seconds! 
  • Slow down, you'll go faster.  Since this was an easy script, I thought I'd "bust it out quick".  Had I taken a little more time, and thought about my approach when I hit a snag, I may have solved it easier. 
  • Pay it forward.  I made a mistake.  One I should  have been able to avoid.  Here it is for you to learn from.  Hopefully, you can use this to avoid the pitfalls I found! 
On a final note, there are several administrative commands that can be scripted using batch files in Autodesk Vault.

Shimming Your Knowledge- Changing Dimension Display in Autodesk Inventor.

SHIM (noun) - A thin piece of material, sometimes tapered, used for alignment or support.

I hectic schedule has required I take a different approach to my videos.

Instead of longer videos, which of course take more time to create, I'm going to create something shorter.  Originally I was going to call them "Microtips", but a friend suggested "Shims" as in the shims used in manufacturing.

But instead of using a these shims to adjust components for proper fir, you're shimming your knowledge for more productivity!

Now, let's use a this tip as a shim to adjust your knowledge for a better fit!

To start this out, here's one from the Inventor status bar, which is visible when a sketch is active, there are several buttons listed there, but for this tip, I'm just going to focus on the dimension display icon.

The dimension display menu expanded at the Status Bar
This icon changes how dimensions are displayed on your sketch, each providing you different information.

The options shown are as follows

1) Value - This option is the default for Inventor.  It shows the numerical value of the dimension, using the number of decimal places as set in the file's Document Settings.

Dimensions shown as value

2) Name - The Name options shows the name of the name of the dimension.  Notice that if a parameter is renamed, then that name is shown, instead of Inventor's default "dx" format.

Dimensions shown as name
3) Expression - This option displays both the dimension name, and the value at the same time.  If dimensions are linked to create mathematical expressions, these will be shown.

It also removes trailing zeros from a dimension, as well as showing additional decimal places for a dimension if it contains more than set in the Document Settings.

Dimensions shown as Expressions


4) Tolerance- If you've applied tolerances to a dimension, this setting will display the tolerances on screen. Additionally, any time a tolerance is evaluated at a value other than nominal, it will be underlined.  This is true of any dimension display setting.

For more on using tolerances in Inventor, see my earlier post!

Dimensions shown with Tolerances


5) Precise Value - This option removes trailing zeros from a dimension and showing the full decimal for a dimension if it exceeds the Document Settings.  It also shows the value of a toleranced dimension, even if it's being evaluated at a dimension other than nominal.

Dimensions showing Precise Value


And that's all for a short tip on Dimension Display!  I wanted to create something short and sweet.  I hope this helps!

I'm thinking of continuing to do this with the "little things" that are always a little hidden in Inventor.  If you think that's a good idea, throw in a comment below!

And a final note!  Here's a video describing the steps above!

How to Attach Content Center to Vault 2015 through the ADMS Console!


Recently, I found myself installing Content Center Libraries into Autodesk Vault 2015.  It was standard operating procedure; I've done it a dozen times.

One thing new to the 2015 version of Vault, is that the Content Center Libraries are downloaded from the link here, instead of being provided on the media or in explicitly in the download.

The installer even states that when you're select it from the Install Tools & Utilities screen. 



No Content Here!  But there is a link to download it.

If you follow the instructions in the readme file, the steps aren't too difficult.  Just download the libraries you want, extract them, click on the batch file, and wait for the libraries to install. 
And if that’s how you wish to install the Content Center Libraries, go right ahead.   It works nicely!

Compressed Content Center on the left.
Extracted and ready to go on the right! 

But if you desire, there is an alternative way as well, if you prefer.

Start out by extracting the files down to the point where you can see the libraries in question, they end in the *.mdf and *.ldf extensions.  For example.  AI2015_Inventor ANSI.mdf, and AI2015_Inventor ANSI_log.ldf if you’re using the ANSI standard.

The ANSI libraries extracted.

Take these files, and copy them into the location with the other libraries for Vault, this location can vary, as an example, the location on my own machine is. D:\Program Files\Microsoft SQL Server\MSSQL11.AUTODESKVAULT\MSSQL\DATA.

In my example here, I've copied the ANSI, ISO, and Feature libraries.  But you can copy as many or as few as you want. 

The libraries copied into the Vault library locations

This will make the files available Vault, but Vault does need to be told to use them.
In order to tell Vault that it’s going to be using these files, open the ADMS Console, locate the Library folder. 

 Once you have that, right click on the folder and choose Attach.

Attaching the libraries you want. 
The libraries that have been placed directory appear, and you can add them to Vault by selcting them and clicking OK. 

You'll have to choose each individually, but this only takes a few minutes for a big library, or just a few seconds for a small library. 


You can add as many, or as few libraries as you need. I'd suggest skipping any libraries you don't want.

The libraries are loaded. 
There it is! An alternate way of loading the Content Center Libraries into Vault. 

But that does beg the question "So what?".  Why would you load the libraries using the alternate way, instead of the other way? 

The truth is, you can use whichever way you want.  It matters little in the grand scheme of things.

But if you've already have the extracted libraries, or you don't have the handy dandy batch file available, this can be a quick way to get where you need to be. 

I've even seen some clever Vault Admins use the Detach option as a way of "deleting without commitment" . They detach the library and make it unavailable to Vault, so users don't have access to it.

If at some point it turns out the users *do* need it, they just reattach it, without having to go through the process of downloading and extracting. 

So keep it in mind as just another tool you can use to make your life a little easier. .

An Exercise in iParts, and a Little Bit of Sharing!


Over the course of the last couple of weeks, I've been working on a little project, and I thought I'd share..

The part I practiced on was a NAS fastener series 1141-1148, in grip lengths from 1/16 of an inch to 6 inches. I built it with the intention of being usable as a library part, not to be one hundred percent accurate.

Since the part is a screw, with the same shape used in several different sizes, I decided to make it as an iPart.

The reason I created it was to refresh my memory when working with iParts, as well as exercise my knowledge of aircraft standards a bit. And it was good practice!

While I didn't learn (or relearn) anything particularly earth shattering, there are a couple of tips that I thought might be worth sharing.

1) Don't forget that you can use Microsoft Excel to edit your part tables.  Using Excel will allow you to using Excel to create equations, or just fill and copy series in the table.

Using Excel can make editing the table *much* easier!

For example, looking at the sample part number 1145-03, the 03 means something.  It's the grip length of the screw in 16ths of an inch.  so 03/16 = a grip length of 3/16.

Looking at that from Excel, you have a formula!  Hello automating a repetitive task!

An example of an equation calculating a screw's grip length.

2) Don't forget that you can use Edit Member Scope and Edit Factory Scope to make adjusting iParts a little easier.

Edit Member Scope means any changes you make to the model only affect the active member.

Edit Factory Scope changed the entire factory, for example, when I need to add a fillet to the whole factory, I edited the factory scope.  When I wanted to modify just the width of a torq head (the sort of Phillips head looking part) for a single variation, I edited the member scope.

The icon for editing member versus factory scope.
3) If you want to generate all the iPart members in a hurry, select them using Shift+Left Click.  Once the parts are selected, right click and choose Generate Files.

The computer may chug a bit, but it will build all the members required for this part.  Saving the trouble of doing it later.

Selecting all all the members and generating all the files to generate all the files.
But after I was done working on this project, I decided that I would go head and share more than a few tips for this part, I'm just going to go ahead and share the iPart.

Of course I do have to offer up a few disclaimers, or at least advisories.

1) I've done my best to make sure that the values are correct.  But there is always the possibility that I suffered a case of fat fingers.  It never hurts to verify if you're going to use it for real!

2) This screw actually uses UNJF threads, not UNF like I've used in the iPart.  However, I designed this with the intention to be placed in assemblies, not to be accurate to the manufacturing level.  Since the default Inventor Thread table doesn't contain UNJF threads by default.

I do have a modified Thread.xls file with UNJ threads in it, but rather than talk people through modifying their Design Data folders, I decided to keep the part as universal as possible, since ultimately the part is only intended to be placed in an assembly.

But with all that said, take the part, use it, and enjoy it by downloading it from my GrabCAD account here!

If you don't have a GrabCAD account, you can download it from this link!

One final note, I found the technical information for the screw at the Coast Fabrication website.  It's got a wealth of information!
