The Online Community About Exciting New CAD Technologies
How do you direct model?
I continue to be amazed at ways that I can accomplish things in SpaceClaim, using techniques that would have never made sense with a feature modeler. One approach I use more and more is cross sectional creation and editing, which works especially well on prismatic and rotationally-symmetric shapes. Taking advantage of edge move and a bit of slice-and-dice, you can quickly achieve compelling results with cross sectional direct modeling. Here’s a little video of me playing with the technique, inspired by a flashlight sitting on my desk:

To try to give you an idea how what using SpaceClaim feels like when you know it pretty well, I’ve left the video unedited. In it, I make some mistakes and show you how I recover. This is the real deal. (The voice over was added later.)
As this community explores different direct modelers, I’d love to see what workflows you guys can come up with, in SpaceClaim or any other 3D design system. How think about your model? How do you like to edit it? I’ve included the battery and reflector assembly so you can make your own flashlight, both in SpaceClaim and STEP formats.
Can anyone else come up with something cool?

I liked your video, and I love the cross sectional modeling feature in SC. Most of the useful information about any complex part or assembly must be displayed this way, so its only natural for an ME like myself to think and design that way. IMO, it is one of the best features of SC. You also mentioned mistake recovery, of which I am getting a lot of experience with. I like the fact that when you don't notice something right away it's not 'back to the drawing board', as I have experienced with other software. There are often many different solutions to a mistake or problem and that flexibility gives a sense of creative discovery and makes the experience fun and not tedious.

I think what you're talking about makes a lot of sense, particularly for M.E.'s, but for industrial designers it's far too simplistic.
Take a model like this one, built and rendered with CATIA V5:
I can't even imagine dealing with a model like this in SC, particularly when someone comes back and asks for the handle to be 5mm longer. In CATIA I was able to move a single plane, and the whole product would update perfectly. In SC it would be nearly impossible. In fact, SC couldn't even build a model like this one, since it uses G2 continuity all over it.
I love SC for what it does! I can only hope that someday it will be able to fulfill my needs as a designer.

Hi,Anyone know how to scale the main design window?I design small objects and would like to see them at a 1:1 scale. In other words, if the object is 8mm by 6mm, I would like to see it life-size on the screen. I can do it on a drawing sheet but that…
