This post is for all Autodesk Inventor Users. How many times have you felt the need to take a screenshot of your Inventor file (assembly, part, drawing etc) and send it across to people who do not have Inventor or even upload the image online. You would have to follow one of the following two options

Option A: File > Save As> Save Copy As> and then select .jpg or .png as extension and save the file.

Option B: Use “Print Screen” key on your keyboard, go to MS Paint or other image editing software, paste the copied image and then save it.

At AR-CAD, we have developed a simple addin for Autodesk Inventor which lets you take screenshot or capture the current view of Inventor and save it as a jpg / png / gif or bmp image. And the best part about this addin is that its for FREE !!!. The addin developed is pretty simple and we just wanted to help Inventor users. We have developed the addin using Visual C#. Below images show an overview of IN-Screenshot usage in Inventor 2009 and Inventor 2010 (which has a Ribbon User Interface). To know more details and download IN-Screenshot addin, check out AR-CAD website.

It presently works on Inventor 2009 and 2010 versions and should also be able work on 2011, when it would be released. We have tested it to work on both 32 and 64 bit OS of Windows XP, Windows Vista and Windows 7.

You are free to try the addin and let us know your valuable feedback.

Disclaimer: Some days ago, I had come across a blog post pointing to ADN Addin of the month being awarded to a similar Inventor addin which saves the active view as an image. I had developed IN-Screenshot atleast an year ago and have no link with the other addin.

What a great year 2009 was to me. I thoroughly enjoyed the roller-coaster ride.

  • It started off with development of IN-Motion (Motion and Dynamic Simulation Addin for Autodesk Inventor)
  • Shifted from Bangalore to Delhi. Joined Indian Institute of Technology Delhi, New Delhi as a Project Scientist.
  • Got married to my college sweetheart in June.
  • Appeared for MS(Research) interview at IITD and got through it :). M.S program started from July end.
  • Finished off first sem of MS with CGPA 8.0/10
  • Launched IN-Motion 2009 for Autodesk Inventor 2009
  • Working on launch of IN-Motion 2010.

I hope 2010 will remain equally good if not more 🙂

Wish you all a Very Happy New Year !!!

Play Safe 😛

IN-Motion: Motion Simulation Addin for Autodesk Inventor

Update: IN-Motion, a Motion and Dynamic Simulation Addin for Autodesk Inventor has been launched by us. Check out the below video for an Overview

Update: Video tutorials on usage of IN-Motion for Dynamic Simulation of Autodesk Inventor Assemblies.

For the past few months, along with my mentor (Aik-Siong Koh), I have been busy developing Motion Simulation addin for Autodesk Inventor. We have named it IN-Motion. Once we are done with the development, it would be available for Autodesk Inventor users, in the form of an addin. Upon installing IN-Motion, they will be able to simulate an assembly both kinematically and dynamically. The following screencasts show the progress we have achieved so far in this regard and very soon we will be launching IN-Motion.

1) Basic tutorial on getting started with IN-Motion. We start with a blank Inventor assembly and place components and apply constraint. Then we start IN-Motion, set rotation to a Insert Constraint (Revolute Joint) and then simulate the mechanism/assembly. Watch high resolution video at AR-CAD.

2) Tutorial on simulating a four-bar mechanism. This assembly has 2 grounded parts and 3 movable parts, with 4 Insert Constraints. IN-Motion allows us to give rotation to one of the Insert Constraints and then the simulation can be made to see the behavior of the imposed motion. Watch high resolution video at AR-CAD.

3) Tutorial on simulating an Elliptical Trammel. This assembly has 4 components. IN-Motion deals with Planar and Insert Constraints in this case and the simulation takes place for an imposed Rotation on one of the insert constraints. Watch high resolution video at AR-CAD.

4) Tutorial on simulating an Engine. We start with the engine assembly that gets shipped along with Autodesk Inventor. Right now, we are not dealing with the sub-assembly(Piston.iam) parts and constraints. We are considering the sub-assembly as a block/part. Upon user feedback, we may actually extend upon the sub-assembly parts. This is mainly because, a lot of processing takes place in our Motion Solver and the sub-assembly parts(if non-trivial) add up to the CPU load. Watch high resolution video at AR-CAD.

5) Tutorial on Dynamic Simulation of a pendulum in Autodesk Inventor, using IN-Motion. We take the pendulum from Tutorial 1 and instead of giving a rotation, we set the value of Gravitational force for the assembly. IN-Motion then passes the gravity to our Motion solver and the dynamic simulation of the assembly takes place. This example is the simplest form of dynamic simulation and complex assemblies can also be simulated for dynamics. We are working on getting velocity, acceleration and force data at any point in the assembly, in the form of a graph. Watch high resolution video at AR-CAD.

Glad am back to CAD World.. Crossroads of my Career

Update: IN-Motion, a Motion and Dynamic Simulation Addin for Autodesk Inventor has been launched by us.

Crossroads in Career Its been quite some time since I blogged. I was pretty much occupied with the Confusion I had in my mind, as I had hit a Cross-Roads of my career. After quitting my job at HeroHonda R&D, I teamed up with my mentor, Aik-Siong Koh in US and we started off with AR-CAD in April 2007. Since he is an expert at CAD (Motion Simulation) and he had used Smalltalk to develop freeCAD, I also had to learn Smalltalk to help him in further development. Our initial plan was to develop Motion Add-ons/Add-ins or Plug-ins for various CAD software such as Autodesk Inventor, SolidWorks, Rhino CAD and others. Somehow in the due course, we thought of exploring Web 2.0 using Seaside, which is a web framework built on Smalltalk. The idea was that I could learn Smalltalk and also explore Web 2.0 as we had plans for integration of Web and CAD.

We started developing Caartz using Seaside. It took us a long time to get it out. During this period, I learnt Smalltalk, Seaside, OOP, Basic Linux Setup and Usage, various Web related configurations such as Apache, load-balancing etc. When Caartz was launched, it was just a lot of things we had learnt and we had no plans to make money out of it. Since I had gathered experience in Web domain, I completely forgot that I had to return to CAD to make Motion Add-ons.

Then I helped a friend to develop a couple of websites and took a Web Developer Job in a Bangalore based Services Startup. Though the work there involved me in whole life cycle of a project and was very challenging, I thought I was missing something there. Being a Mechanical Engineer from a reputed Engineering College with a lot of interest in CAD, I had a feeling that I was not doing what I was supposed to do. After a couple of months in that Web Startup, I quit it and again I have teamed up with my mentor in US to develop CAD Add-ons.

This time, we are very serious about our path we are going to follow to become a very known name in Motion Simulation Domain. We have completely revamped AR-CAD website as the first step. My mentor already has Motion Simulation code in Smalltalk. I am learning VBA and .NET C# to develop an Add-in which talks to both Autodesk Inventor COM API and our Smalltalk code. As of today, I am able to make simple VBA Add-ons for Inventor and hopefully within next 6 months, we would be ready to sell our Motion Add-ons for Inventor. Once it is done, we would then develop Motion Add-ons for other CAD software.

Jist of my post is that I had come across a Crossroads a year ago and chose a road which took me to Web 2.0 domain. Somewhere down the line, I realized that I wasn’t enjoying it and came back to the crossroads and now I have chosen the road which takes me into CAD world and I am glad that I am finding it interesting and challenging.

Finally, I start Blogging

Ganesha Image

Its been quite a long time since I had thought of starting to Blog. It was mainly my Hectic Schedule and Laziness, more of latter which held me back from doing. Anyways, now that I have decided, I shall try to make this Blog more of my learning experience, which includes Seaside, CodeIgniter and a couple of other Web 2.0 Technologies.

Whatever I feel important, I shall mention about it, be it just a link to a very informative Blog post, as it would also help me maintain my Bookmarks.

Till Now, I was saving all important information onto my Google Notebook. I shall try to move them to this Blog as well.

The reason why I have put Lord Ganesha’s image is due to fact that He is believed to be Solver of all Obstacles. Lets hope I have a nice sailing in the World of Blogging.
