    making springs compress in a simulation.

    hydromech, Well, I don't have Invenor 10 handy, but I tried it with Inventor 10 about 1 month ago and it was OK.

    making springs compress in a simulation.

    hydromech, dXX is a pretty wild guess in this procedure, it works exactly the same for d3 or any other number of digits, sorry for that. I can't see your design, but generally you would have 4 constraints involved: 1. workplane A to part 1 (any part). 2. workplane B to part 2 (other part). 3...

    changing dimension style

    cadranger It also states you can change geometry to normal but I can't find that button or pull down item either. Depress the driven dimension button? [pipe]

    changing dimension style

    DesignerMike, Simple example: flip dimension from + to -. Make any dimension driven, pull it to the other direction, make it normal back and edit the value. This way is several steps shorter than any other solution. I am using driven dimensions and construction geometry quite a lot recently...

    Transfering holes in Autodesk Inventor

    Well, you don't project holes, only a geometry in sketch mode. It's up to you how to use that geometry afterwards. It makes sense to try.

    Positional representations in assemblies?

    Did you make your subassembly flexible?

    Torque Measurement

    I've seen an arrangement for measuring torque on car flywheel. It involves sensors coupled with clutch pins and a complicated electro-mechanical design, which seems to be know-how. Precise measurement of torque is obviously not an easy task.

    Place a Constraint to Sketch geometry

    Insert constraint can be substituted by 2 or 3 mate constraints. It is true that you can't attach work point, plain or axis to assembly sketch. But you can attach driven dimensions and use them when you offset workplanes. What I offer is a practical workaround, I never tried to argue with...

    Place a Constraint to Sketch geometry

    I use Construction geometry and driven dimensions in assembly sketches. You can always offset a workplane using driven dimension as offset value.

    voice commands

    AFAIR, voice detection interface is a part of MS Word object model. Which in its turn is accessible through VBA IDE. Try it, sell it, make money :).

    Adaptive coils in IV9?

    1. Create 2 parallel work planes (A, B), make one of them adaptive. 2. Create perpendicular workplane (C). 3. Enter sketch environment, use C for sketch plane, and create imprints of A and B on C using project geometry function. 4. Draw line (D) collinear to the imprint of A, make it...

    Adaptive coils in IV9?

    Once you have adaptive workplane, create a sketch (for reference only) with line collinear to workplane imprint, add driven dimension from other workplane (where your coil starts), use this dimension in coil dialogue box for length of the coil.

    Interference fit between helical coil spring and rod

    I would refer to each coil as a separate beam and (as soon as we know the deflection, which is roughly ODrod.max-IDspring.min), it is possible to calculate the stress. Imagine each coil straightened and represented as a separate beam with round section and 1.5mm diameter and the length of...

    Forced Air Cooling

    Cooling process can be computer modelled and presseure loss thus estimated.
