I use Google SketchUp when developing rudimentary form and spacial configurations. For more sophisticated formal exercises Rhino (in conjunction with Grasshopper) is adopted.
Adobe Illustrator is my go-to graphic design, print and presentation layout software. The integration of vector based content and complex raster images from Photoshop make usage seamless.
Autodesk Revit is emerging as the industry standard from technical architectural drawing. For me Revit is never used as a design tool. It is simply a means to efficeintly document a design.
Autodesk 3DS Max is a complimentary piece software to Revit and can also work in association with SketchUp. I use 3DS Max for intensive, photorealistic, rendering tasks and animation.
Adobe Photoshop CS6 and Elements 7 are process critical applications. I use them heavily for texturing, diagramming, cutting and merging of images as well as for other image adjustments.
TiltShift is a Mac only application that applies tilt-shift effects to images artificially. Generally I use this software to post process renders and cut images to create a more uniform appearance in terms of light and colour.
Keynote is used to create quick animations of projects to improve engagement and understanding. This software is used in the final stages of my design process and operates only on Mac.
Handbrake is a Video Processing application that I use exclusively to reduce the size of exported animations. This software will retain all resolution aspects while reducing file size by up to 80%.
Finally Adobe Acrobat Pro software is used to collate documents and reformat images and PDF into a final submission. The power of Adobe Pro is significant in terms of file size reduction features and OCR.
Adobe InDesign - used to compile multi-page presentations, print publications, books and posters.
