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...

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]
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...
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.
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...
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...
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.
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...
Sorry, pennpoint,
Isn't the scheme you describe just a big gas spring? And doesn't it bear the same disadvantages on it? You describe the valve that controls the flow, but will the viscosity and the flow be independent of ambient temperature changes during the day?
Just curious.
Gas spring performs as normal spring providing smooth movement due to damping effect. It neither has a constant force during the stroke, nor constant velocity (moreover, these parameters can change with a change of ambient temperature).
On the other hand, it can give you time that you need, it...
Gravity is a good point.
As for gas springs that is why I said that I hardly imagine the whole process. As nicklasw wrote in his post, retracting movement shall follow inserting the plastic immediately, otherwise some control device must be attached to the system (mechanical, not hydraulic, most...
Though I still hardly imagine the whole process after your description, I think that this link http://www.bansbach.de/englisch/startseite_englisch_3.htm may be useful. Gas spring would provide you with slow motion without any use of electricity, just as you have described.
