Richard, You seemd to have made a common mistake, while computing mass properties in AME. In AME R1, we calculate MASS moments of inertia, which applies to any object with volume,3d solids. It is different from AREA moments of inertia, which apply to 2d objects. Polar moment of inertia is…

CarlThe first thing I tried was to use AME, but got erroneous solutions. I wasn't aware that the calculations are based on the current UCS. You must have to have the origin at the corner of the I beam or sometihing like that. Anyway, I received another reply and downloaded…
Mike, To some extent. When I was an Aerospace Engineer (still am I think ) we did "a lot of glue" with AutoCAD, FEM programs, fluid analysis, etc. That's how I became "sucked into" this market. Our products BlockSOLID & FAC-MAN aren't drawing automation in the way of a parametric…
Angelo – I like vaporware. It always works perfectly . I'm sure I'm miss-communicating as well. We are just about to that point. The problem is that there always seems to be some change that screws something up. I would also like to here from anyone else out there and…
Mike, As I mentioned in my last mail, we have (hopefully !) addressed your problem with AME R2. At this point, I am unable to discuss, more in details. So, instead of writting Solids off, I would wait for sometime, till we can discuss more in details the features of…
Mike, Ahhh, I see where I miss-communicated. I guess what I was suggesting was that a change is "completely re-created" via my "vaporware" external parametric program. The dimensioning may be tough. I guess my thought was that given parts with "similar" geometric qualities that are generated from scratch, the different…

Angelo – The problem is the dimensioning. We have done the LISP for 2d drawings and I would like to go to 3d solids. The AME manual suggest that you create separate 2d views and then the changes are what will kill me. If I change the solid I then…
Last year I worked on several parametric 3D spiral routines – which I call "Spiralitis". I gave up because I did not know enough about spring and screw manufacturing and could not access such expertise. Cany you send any drawings of the springs you have in mind? I especially want…
Ian, If you need the mass properties of the spring under varying conditions, you might still be able to approximate it with AME close enough for your specifications. Of course the best approach would be to sweep a circle along a path but AME will need to support NURBs before…
Dear Dieter, Thanks, I was expecting the answer that yoyu have given me. We need to do more than visualization. We were hoping to create springs under different conditions to get moments of Inertia, centroid etc…etc But thanks anyway. Is there any API products being developed ? Ina…
Ian, At this time, AME cannot create swept solids through a parametric path, even with API. This means that you can only roughly approximate the spring. You could do this by using the 3dpoly command, feeding it calculated points. You could create a circle at each vertex normal to the…
#Spiral Spring
Message #21658
We are trying to design a special purpose spring fro a client. We are attempting to do that we AME and having problems trying to mdel the shape. Does anyone have a sping routine ? is anyone doing any work in API or is it just shipped as a hang…
