Calls, Proposals, Universities, Speeches

Posted: 29 Apr 2016 08:48 AM PDT

Some quick updates to round off the week… Firstly, a couple of "calls for proposals" have just gone out. Autodesk University 2016 is once again being held in Las Vegas, but this year it'll be earlier than usual: rather than being held right after Thanksgiving, it's now the week before, from November 15-17, 2016. This is going to be a welcome change for all US-based presenters, in that they can deliver their classes at AU and then take a well-deserved Thanksgiving break rather than spending it making last-minute changes to their slide decks and demos. If you're interested in...

It’s Time for AU 2016

Posted: 27 Apr 2016 11:30 PM PDT

Actually, it's time for proposals for classes. If you have some cool tips and techniques or an interesting project to share, you should think about submitting a proposal and maybe you can be a presenter as AU this year. As a presenter you get the satisfaction of sharing something that's important to you with your peers. But you also get an AU event Pass, (conference only; does not include travel or hotel accommodations). And you will also receive a $400 cash honorarium for each additional session they lead.  You can learn more at the "Call for Proposals" AU site.

AU2016

Whether or not you feel like you're up to the challenge of presenting, I would love to hear suggestions for topics on classes you would like to see related to both the Inventor and Fusion API's. Remember, even if you're unable to attend AU in person, you're still able to benefit from the content from previous sessions.

Taking control of the 3DORBIT command in AutoCAD

Posted: 27 Apr 2016 09:02 AM PDT

Do you 3D?  If you do, you most assuredly are familiar with the 3DORBIT command (or at least one would hope!)  

For years - AutoCAD has determined the centroid of the display when orbitting based on the center of the entire model.  This center doesn't always work effectively when you have objects off in one or more directions.

AutoCAD 2015 introduced an option so YOU could control the centroid and consequently orbit about any part of your model you see fit!  Check out my Cadalyst video and take control of the 3DORBIT command for yourself!

 

Do you feel powerful now?

Stoking the Forge

Posted: 27 Apr 2016 08:14 AM PDT

It's an exciting time to be a developer working with Autodesk technology. For my entire career at Autodesk, I've been a platform guy at a product company: while much of AutoCAD's success, over the years, can be indirectly attributed to the existence and use of a rich set of APIs, Autodesk has largely (and this is of course a gross generalisation) approached the exposure of APIs as an afterthought, or at least a secondary activity. Some teams have been better than others at building a platform and then a product based on top of it – a shining example...

Fusion Meetups and Melting Butter

Posted: 21 Apr 2016 02:58 PM PDT

I had posted a few weeks about some upcoming meetups discussing the Fusion API. To generate some interest for the meetups I created a small animation of some butter melting and forming a puddle in a butter dish. Here's the original animation.  At the meetups I presented an introduction to Fusion's API and shared how the animation was created. The meetup in Seattle was hosted by Microsoft and Jeremy Foster, from Microsoft, was kind enough to record it and post it on Microsoft's Channel 9.

Butter

 

If you're wondering how I created the animation and are imagining something elaborate you're going to be a bit disappointed. The good news is that it's probably simpler to do than you're expecting. First, there are not any elaborate volume calculations to make sure the volume of the puddle matches the volume that has melted from the cube. I just tried to do what looked good. The melting of the cube and the formation of the puddle is done using parameters so the majority of the work is building the model, not writing the program. Although I'm using Fusion here, this is all possible with Inventor using the same concepts. What the program is doing is actually very simple; there's a loop where in each iteration it changes the value of one or more parameters, updates the model, and captures the screen as an image. That's it. The challenge is building the model so you get the behavior you want by editing parameters.

Let's look in more detail how the butter model works. There are three components that make up the model; the butter dish, the block of butter, and the puddle. Below, three sketches are shown that are the key to making it all work. The sketch at the bottom defines the shape of the puddle. The other two sketches are used to create a loft feature which is subtracted from the block of butter.

Butter2_thumb5


Below is a detailed look at one of the sketches used to define the loft that cuts away the block of butter. The sketch consists of three lines and a spline. The vertical position of the points on the spline is being controlled through the use of dimension constraints. When you place a dimension in a sketch, a parameter is automatically created that controls the value of the dimension. By editing the parameters the points on the spline will move up and down. The program modifies the parameter values so that the points slowly move down, causing the block of butter to disappear.

Butter3_thumb2


The puddle uses the same principal but is slightly more complicated because the points don't just move down but move in two directions. Below is the puddle sketch. To move the points in two directions there are two dimensions to each spline point, one controlling the horizontal (x) direction and another controlling the vertical (y) direction. To make the puddle grow, the parameters are edited to slowly move the points "out" away from the cube. I didn't worry about how the puddle intersects the butter dish. As it grows it will end up extending into the dish, but it looks ok because you can't see the overlap.

Butter4_thumb2


Below is a snapshot of most of the parameters that are used to drive the model. Sketch7 is the puddle sketch and Sketch8 is one of the loft sketches. I named each of the parameters a name that made sense to me so I knew which parameter to edit to get the corresponding point to move in the way I wanted.

Butter5_thumb3


Below is a sample program that demonstrates the full basic workflow where it changes a parameter through a range of values and captures and image at each change. It has a loop where it continually changes the parameter named "ToChange". In the example below, the loop goes until the parameter reaches a specified value but it could also go a pre-defined number of steps. It depends on what you need in your specific case.

import adsk.core, adsk.fusion, adsk.cam, traceback    

def run(context):
ui = None
try:
app = adsk.core.Application.get()
ui = app.userInterface

des = adsk.fusion.Design.cast(app.activeProduct)

# Define the values that control the stepping.
startValue = 5
endValue = 10
increment = 0.1

# Get the parameter to change.
param = des.allParameters.itemByName('ToChange')

# Iterate through the parameter changes.
currentValue = startValue
frameCount = 0
while currentValue < endValue:
param.value = currentValue
currentValue += increment

# Allow Fusion a chance to update.
adsk.doEvents()

# Save the current viewport as an image.
frameCount = frameCount + 1
filename = 'C:/Temp/Animate/Test' + str(frameCount).zfill(4)
app.activeViewport.saveAsImageFile(filename, 0, 0)

ui.messageBox('Finished.')
except:
ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))


The code is really fairly simple. It's all a matter of how creative you get with your parametric model. You can use anything to determine the parameter value and you don't need to be limited to changing a single value. In the melting butter example, I change several values and use a random number so the butter melted and the puddle formed in a slightly random way.


The result is a directory containing a bunch of image files. There are many products that will let you combine the images into a video. For the gif file at the top of this post, I used GIMP (Gnu Image Manipulation Program).  For a higher resolution, full color animation I used another free tool called FFmpeg where I used the command line below to create the video:

ffmpeg.exe -i C:\Temp\Butter\Images\Butter%04d.png -b 5000k -r 30 output.avi

Here is the Fusion model and the Python program for the melting butter example. When running the code it begins by displaying a message box to allow you to reset the parameter values back to the original starting values and then an option to run through the parameter changes and generate the images. If you look at the code you'll see that it does some work to reposition the history marker in the timeline to reduce the re-compute time because Fusion re-computes with every parameter change without an option to delay the re-compute. It moves the marker to just before the features that will re-compute, changes the parameters and then moves it to the end of the timeline so there is a single re-compute of the model with each set of parameter changes.

I've been spending more time looking at generative design in recent months (although this is a relative thing… I've still only posted once about Dynamo, for instance). So far a big chunk of my research has been understanding what's going on in different parts of the company with respect to generative design. As part of this effort, several months ago I chatted with Anthony Hauck who heads up a team focused on generative design in the AEC space. He talked to me about Project Akaba – an early generative tool for space planning – and its successor, Project Fractal....

Merging AutoCAD blocks using .NET

Posted: 18 Apr 2016 01:28 AM PDT

I decided to dust off Visual Studio and write a quick AutoCAD app, this morning. It tackles a question received via a blog comment from Pankaj Potdar, over the weekend. I have two blocks with different attributes I want to merge them in single block, and I don't want to create any nested blocks. I haven't had much time to spend on AutoCAD, of late. Part of the reason has been work-related: I'm heads-down getting the VR/AR track in shape for the upcoming Forge DevCon, as well as spending time on new duties in Autodesk Research. The other part...
