Link: Astropad

Astropad, released today, is a new piece of software that connects the dots between two pieces of technology you might already have - an iPad and a Mac - and allows them to work as one. Our iPads can now be used as so-called professional graphics tablets for $50 ($20 if you're a student). 

The developers of Astropad have solved a problem that has nagged this kind of interoperability for years now which is to cut down on the lag between input and results on the screen by creating something they call Liquid:

Creating Astropad required innovative new technology we call LIQUID. The result is stunning image quality and responsiveness never before seen in similar tools.

LIQUID is true to your source material with color corrected output and retina resolution. What you see on your iPad is the same as on your Mac.

I also love this graphic on their site. Fingers crossed indeed.

Previously using Airplay we got 30 frames per second (FPS) and with Liquid we get 60 FPS. This helps a lot.

I'm hopeful of Astropad because it solves the very real problem I've always had with standard graphics tablets which is the disconnect between the hardware and the screen, and I've never considered myself to be a person that could justify buying a Cintiq. Being able to have direct input between the stylus and the pixels is a big deal, and I'm excited to try this out and see how well it works while keeping in mind it's a v1 product. Will it be as responsive as a Wacom tablet? Nope. But it also doesn't cost $350.

What do you think about it?

Update: I've tried Astropad out, and it works surprisingly well. I used it on the Mac version of Notability and Photoshop CS6 connected between my iPad Air and my 27" iMac.

When you download the Mac app and install it, and then install the free iPad app, you go through a simple pairing process to connect the two over wifi or USB. The instructions are very well done. Except... I tried it in my office where I have no control over the wireless system, and it didn't work. Both devices must be on the same wifi network, which they were, but for some reason they couldn't communicate. To be fair, there are hundreds of devices on that particular wifi so I'm not surprised they couldn't find each other. I ended up simply creating a wireless network on the iMac and connecting to it through the iPad. Once that was setup, they found each other right away. Another option is to do a hard wired connection but I don't carry a Lightning cable with me. Plus, I really wanted to test it out over wireless to see how well it would perform over the air. 

In Notability

Notability is a note taking app that has some really nice ink technology and I wanted to see if I could use it with a graphics tablet to do markups (redlines) on PDF's in realtime during a GoToMeeting while sharing my screen. I don't think the developers were really thinking of this particular use either, which was another reason I chose to do it.

Astropad excelled at what it was designed for, which was allowing me to have direct input on my iPad with my stylus and having my work be mirrored on my Mac. There was little to no lag between the two. For a first release, it is very impressive. 

What it did not excel at was giving me Notability's controls on my iPad screen, which again I can't really blame them for. What this means in real world applications is that I had to do a lot of back and forth between my work on the iPad and using the mouse on my computer to switch between tools, brush sizes, and colors. I don't think Notability has keyboard shortcuts for what I need, and that would make things much easier. 

In Photoshop

Astropad works even better in Photoshop, which seems to be the app's initial target market. It's the same great painting interface, you can zoom and pan around your document right on the iPad, and there are common tool shortcut buttons on the iPad's screen for brush sizes and more. These really help make the experience much better because you spend a lot less time switching over to your mouse to get to your most-used tools.


It would be great if more Mac app developers look to have an Astropad connection now that it's out.  Having software shortcut buttons right on the iPad's screen would be welcomed and would lead to more sales for sure.

Never once did the connection fail. Even after long pauses between uses, I could just pick up and continue without re-pairing the devices.  

Probably the biggest challenge is using Astropad between two devices with such different physical screen sizes. I was going between 27" and 11". There is a lot of time spent panning around to see what you want to see on the iPad. I'm sure with more use I would get much better at it. There are three zoom settings that you can access on the Mac side - full screen, 100% and 200% modes. I was usually in 100 or 200% mode because I was painting and the scale of the image on the iPad made sense. Full screen between these particular two devices makes no sense, but it might for other people if their devices are closer in size (like a notebook for instance). 

I can't wait to see where they go with this. What if Apple comes out with rumored iPad Pro? what if Apple comes out with their own stylus? This could really change the graphics tablet game for professional use.

My advice is to give it a try for yourself. The app comes with a 7 day free trial and you can see if it would work for you. Let me know how it goes. 


Link: Google Earth Pro is Now Free

Over on the Google Lat Long blog, the latest news is that Google Earth Pro is now free. I use it on every single project for my virtual pre-site visits and for lots of contextual research. It helps me get a jumpstart on my design and has been an invaluable tool. It being made available for free is great news. It's better than the previously free version (just called Google Earth) for a few reasons:

  1. You can export super high res satellite imagery and use it as an underlay for your 3d modeling - up to 4800 pixels wide. The extra large exports come in handy when making large format presentation boards. Tip for underlays: turn off Terrain and 3d Buildings layers, and get a straight down view by Command+clicking and aiming straight down with your mouse.
  2. We can see property lines and US Parcel data. It includes lot size as well!
  3. Turn back time and see how neighborhoods have developed by skimming through old satellite photos with the Historical Imagery slider.
  4. Use the Path and Polygon tools to take measurements. Turn on the Ruler in the tool bar to see how long the paths you draw are.

Here are a few other things you can do with Google Earth; either free or pro versions:

  1. Find a 3d building that highlights in blue. You can click on them, and download them with textures from the SketchUp Warehouse. If you use SketchUp, they will come into your project geolocated and can be great 3d context.
  2. Use the heck out of Street View. Just keep double clicking all the way down to a street and you'll get into street view mode. Then click on the street in the direction you want to go, or scroll with your mouse wheel and drive down the street. 
  3. Take a trip to the Moon or Mars and explore. There is some crazy stuff embedded in those models.

These are the most valuable things I use it for on my projects. What do you use it for? Leave a note in the comments.

✱ Q&A: Using Maxwell Grass 'Level of Detail' for Faster Renderings

Here's something thing that comes up every once in a while regarding using the Maxwell Grass extension - running out of memory. Those grass blades can take up a lot of RAM when rendering and if your surfaces that you apply the grass to are too large, the rendering can be extremely slow and sometimes even fail. 

And no one likes a failed rendering!

So here's a quick screen shot of some settings to look into when using the grass extension called Level of Detail (LOD):

Use the L.O.D. settings in the Maxwell Grass extension to control falloff of grass blades.
Click to enlarge.

Basically if you set it up correctly, the further away your scene gets from the camera POV, less grass blades are generated. You can control how this works. This is a HUGE deal when your surfaces are expansive. The image above is an extreme example because of how closely I placed the distance values together, but it illustrates how they work. Once the distance passes the Minimum value, the blades falloff to the Maximum Density and then hold beyond the Maximum distance value. This way there is no step in the amount of blades, rather you get a nice even gradient from full to partial density.

There's a bit more info about this in the Maxwell Render help documents near the bottom of the page which you can reference here.

Use this tip to speed your renderings up drastically!

This tip also comes in really handy when using my Maxwell Grass Preset Pro Pack. Check it out and take your images to the next level if you're using SketchUp, FormZ or Bonzai3d.

✱ Q&A: Troubleshooting Emitter Lights in Maxwell Render for Beginners

I got an email regarding troubleshooting emitter lights in SketchUp using Maxwell Render over the weekend, and I thought I'd post my answers here because it could be useful for you. Lots of people struggle with emitter lights when they're first starting out using Maxwell Render and think that the software just doesn't work when in fact you're probably just used to the brute-force techniques required by other rendering programs. I know this because that's what happened to me when I first tried using emitters in Maxwell.

Video: Subdivision Modeling and 3D Printing in FormZ 8


This is a great webinar by the folks at AutoDesSys showing the new capabilities of the subdivision surface tools in version 8 and how they can get you to organic 3d-printable objects pretty easily. 


In this webinar we’ll show the power of form•Z’s subdivision modeling and 3D printing capabilities by walking you through a series of actual 3D printed projects modeled exclusively with subdivision tools and features.

In this session you’ll experience:

  • Powerful subdivision modeling and how it can be used in your project workflow.
  • Seamless conversion of subdivision models to NURBS or Quad Meshes.
  • How the inherent quad mesh personality of subdivision objects lends itself perfectly to 3D Printing.
  • How converting your subdivision models to NURBS adds an additional layer of flexibility to your design capabilities.
  • The advantage of minimal time involved with analyzing and prepping the model for 3D printing due to the subdivision personality.


✱ How to Print Large Format PDF Drawings to Scale on a Mac

With more and more of the world going paperless all the time, Adobe's Portable Document Format (PDF) has taken over much of the architecture and construction industry as the preferred file format for sharing drawings. In fact, many estimators and contractors that I work with don't have the ability to work with anything else. I'd love to just give them my BIM file but that's another rant for another time. For some of us, this could mean having to purchase (or subscribe to) the Adobe Creative Cloud to get Acrobat Pro or buy Bluebeam to be able to create PDF's. Granted, these professional programs allow you to do much more than simply create PDF's, but the cost of entry is fairly high.

There is an alternative. I've recently found a free open source PDF printer that solves a few problems called PDFwriter for Mac. Click through to see the tutorial.
