Creating Custom Inventor Content Center - Part 1

I haven't spent a lot of time with Content Center in Autodesk Inventor.  It's just one of those things I always told myself I'd get into, but like so many projects and intentions, it was set aside for more pressing matters.

But during the holiday break, I found the need to dive into Content Center, and start peeling back it's layers and start creating some custom content.

One of the things I found, was once I got into it, was it's not as intimidating as it might look at first glance.  Once I dug into it, I found that, dare I say, it began to make sense.

So I decided to start sharing what I've learned (and I'm still learning).  I hope you find it helpful.  These are just my thoughts on what I've seen so far.

Since there are so many facets to working  with Content Center, I found the prospect of doing it in one big blog post pretty daunting.  So I decided to break it up into smaller bits that might be easier to digest, and yes, it's going to be a lot easier for me to write! 

So for starters.  Let's talk about this Content Center thing.

To get started, what exactly is Content Center?  

Content Center is a series of libraries that generate standard components when you place them in an assembly inside of Inventor.

Now that's not to say that you can open up your Inventor media, and find a series of folders full of Inventor *.ipt files and copy them locally.

This is a misconception I sometimes hear.  That on that media, is a whole bunch of *.ipt files you can get to.

The files actually contain the databases that build the components.  So when you place a component in an Inventor assembly, Content Center builds that component and places it into the assembly for you.  The functional word is "building".

Content Center using the following procedure to build the parts.

1) A part is requested from the Content Center databases
2) It checks to see if the part has been published already.
3) If the answer is yes, it retrieves the part and places it in your assembly
4) If the answer is no, it builds it and puts it your Content Center directories, so it will be available for the next time.

So that's what they are?  But where to we keep them? 

There are actually two different answers to this one.  There's the Content Center stored locally (Desktop Content Center) or Content Center managed via your Vault Server Console.

Desktop Content Center works great for single users, or users who don't want to install the Autodesk Data Management Server on a network server for some reason.

The advantage is that this is a pretty simple model to work with, since everything resides locally on your machine.

The disadvantage is that only the machine the Desktop Content is installed on can use the libraries.  There's no sharing across machines.

So if you have several machines that are using Content Center, and you want to use Desktop Content, each machine will need to have it's own copy of the libraries.  This may not be too bad, but what happens when you start customizing your libraries?

It can be tricky to manage indeed!

Content running through your Vault Server is intended for a central Content Center shared among several users.  Even if you're not using Vault, you can run Content from the Vault server.  You just don't use the "Vaultiness" of Vault.

The advantage of this model, is your Content is managed from one location.  The bad side?  You now have a server, network connections, and possibly even I.T. to work with.  So it can be a little more involved getting started.  Although since everyone is now on the same set of libraries, it can be easier to maintain.

That will choose where you're accessing Content Center from.  

Wow, that's a lot of writing!  So I'll save the rest for later.  Next, we'll talk about creating custom Content Center components!  

If you're wondering, I use Desktop Content.  Why?  It's actually, it's for a reason that is completely different than most will encounter. 

I'm constantly uninstalling and reinstalling Vaults.  Far more than the user in the "real world"  for that reason, I run a Desktop Content Vault.  That way I don't have to worry about which Vaults have what Content attached!  It's as simple as that!

Using View Representations on an Autodesk Inventor Drawing

t's actually not that difficult.  There's just a few tricks to be aware of.

I like to use it when I need to consistently turn off certain parts, as well as bring colors from the assembly onto to the drawing.  Usually when I'm drawing up a woodworking project, where I want a reasonable facsimile of the wood grain.

I also used it on a project where an enclosure was having several internal components being made visible & invisible as design changes were being made. 

I admit, it took some getting used to, but view representations made it much easier to control the visibility of components on several different drawing sheets.

Personally, I think it's one of those items that can really help someone, but is often overlooked.

So here we go with the video that continues what we started last week!

Driving Bolt and Nut through Dynamic Simulation

To do this we will have to give proper constrains. So let us start. You will need the necessary files to carry out the tutorial which is hosted on the link below:--

Bolt-Nut-Dynamic Simulation.7z

Create an assembly file and place the bolt part and nut part and give axis mate them. Now place a mate between the faces as showed in the video, this is done to place the Bolt at the start of Nut and we will drive it for 1inch. Some data of Nut and Bolt is also displayed there. Now suppress the mate given between the faces of Bolt and Nut, because Nut has moved to the required position. Now go to Dynamic Simulation environment. Insert the screw joint between the Nut and Bolt as displayed in the video. Fill 0.1 in the pitch. In the standard joints give imposed motion on Bolt of 36000 / second as displayed in the video . Now fill the Image value 1000 in the simulation player. Now play with simulation player. Now Nut will cover the 1 inch distance. That is all.

Animation using Autodesk Inventor - Driving pinion on a rack

To do this we will have to give proper constrains and through drive constraint we can animate a pinion on rack. File used in the tutorial is hosted on the link below:-

After creating a new assembly file and saving it first we will place the penion part. Because it is grounded and we want to re-constrain it, remove its grounded position. Very first we will mate the pinion's axis to the X axis of the assembly then we will mate the assembly's origin centre point to the pinion's origin center point. Now the pinion is moving only on the axis displayed. That is all for pinion part for now.

Now we will place the rack in the assembly. We will give tangent mate as displayed in the video. Select the outside solution. Afterward we will give 0 degree angle mate the assembly's XZ plane and Rack's XZ plane. Now we will mate Penion's Top plane to Rack's (User Defined) Work Plane 7. Now suppress this mate because rack has moved to the place which we require. Now we will give 0 degree angle mate to assembly' XY plane and Pinion's Top plane. Now we will give Rotation-Translation constrain between Rack and Pinion. First select the part rotates here it is pinion and then the rack it is important. In the distance specify 4.725 units. Now drive constraint the angle mate 2 constrain as described in the video if it is moving in other direction fill -360 degree or moving very fast fill less amount in Increment tab. When you will give the mate and it does not look like in video then try flush mate to get desired result. That is all.
