If i just set the rotational speeds in an animation i can't evaluate the backlash that occurs when a mechanism is started, or when its direction is inverted. This would only be possible using a physical simulation, since a gear constraint would most likely assume perfectly meshed gears with no gaps. //How accurate is the existing collision detection? If a gear could be made to test a very small movement "step" in each direction from its collided condition (disregarding those directions in which it is constrained) and adopt the position in which it was released from the colliding surface it would be satisfactory for me. Allowing for gears to be simulated in mechanism mode would remove one source of "false" collisions in the gear to gear interfaces, letting the designer check for other interferences. Not to mention that it would let the user specify a LOT less of those pesky smartmotions if you animate with mechanism mode on. Speaking of which, is there any way to edit a smart motion once it has been created? I only seem to be able to change its duration, but not the angle of rotation, for example.

Same thing hapens here, it's like those board games where you have to get to the finish line on an exact dice throw. Happens both when zooming with the mouse scroll wheel AND when zooming with ctrl + mid_mouse_button + mouse_move_Y

I think the rendering with the lighter background is better because the reflected light from the background helps define the shape of the spring, and color-wise ties the reflected color from the top of the metal together with some visible element from the scene, making it less artificial. Also, the lighter background produces a clearer silhouette for the whole part, making it more recognizeable. This would be good if it were a catalog item that had to be shown ias small thumbnails too. //well, on second inspection it seems about the same, the top blends in to the background in the right image, and the bottom blends in on tha left image. Ideally, perhaps the background would have a slight gradient that could yield a good contrast on both top and bottom of the part. The faint reflections and shadows in the ground plane also help to define it as a physical object on a surface rather than a physical object floating around in outer space.

I see. Is there some way to set the angle of one gear constrained to the angle of the other multiplied by the ratio, multiplied by -1 (to invert the rotation)?

Hey there fellow IronCAD users. Does anyone know which set of constraints to use to allow mechanism mode to solve for a pair of meshed gears? (bevel and spur) I searched the documentation, tutorials, the internet, these forums and I'm finding nothing of use. Please shine a light of guidance my way. The gears i'm using are the standard catalog gears under tools

Irradiance cache is a way of speeding up a render by evaluating fewer points, but choosing these points in a way that permits an interpolation of values in between them. If you simply switch it off you should see a lot more "dots" during the render. Sometimes irradiance cache produces bad results on small details because the sampled points in a region fail to represent the particular feature of small details (such as sharp edges). Right-clicking the rendered image in ironcad and selecting Resize to default (1:1) sometimes helps to get rid of some holes that appear. Apparently the render window is resizing the image is linearly, leaving holes wherever there is information missing? Saving the image shouldn't be affected by this though, so I have no idea what's causing it for you. Are you using printscreen to capture the image directly from the render window? I'm sorry i have nothing better to offer. Lycka till.

I can't open your scene file. There is an externally linked reference that appears to be crashing ironcad completely. It looks like the image is being displayed at the wrong pixel ratio or that irradiance cache is enabled and is somehow using bad data for interpolation. edit: Ok, I managed to open the file - but the desk is gone, all i have is the floor and the background image.

Hello, I am wondering if there is any way to export 3D PDF files from Ironcad (V11) that will preserve the textures. Does the U3D format (exportable from Ironcad and readable from Adobe Acrobat professional) support textures? I tried decals, applying textures on faces and parts as a whole but nothing seems to go through. I know the PDF format itself supports the use of textures (and even javascript controlled animations) so there should be some way of getting it done.
