    Creo 10 Pro/program Problems

    Reusing the variable. Plus I could not get the inputs (YES_NO) to work so I just did number and the did position1 = 1, position2 = 2, etc. Then used ball_to_Ball with a value for each position. First I defined the variables Distance_1 (as you said) = #, etc If position = 1 ball_to_Ball =...

    Creo 10 Pro/program Problems

    oh darn I did flip them. Now I am getting errors.... INPUT POSITION1 YES_NO !*** ERR: line contains a bad symbol or is otherwise invalid “DO YOU WANT POSITION1?” !*** ERR: line contains a bad symbol or is otherwise invalid Same for the others RELATIONS IF POSITION1 == YES !*** ERR...

    Creo 10 Pro/program Problems

    Hi fellow Creo Users, I am currently running Creo 10. I have a situation where I need to create a Pro/program. And for some reason I can not get it to function correctly. I have gone through many examples on this site and via the google with little luck getting this to function correctly. I...

    Free Body Diagram - Ball and Socket (both ends)

    Good day fellow Engineers, A co-worker and I are having a discussion about a ball and socket mechanical joint. He says the reason for a ball joint is so the ball can move freely, and the socket force load is ALWAYS normal to the center of the socket (cup). So, he says to set up a FBD. So, I was...

    ANSYS Mechanical and Max Cores

    Hello good people, I have a question about ANSYS Mechanical. Let's assume I have unlimited HPC packs available to me, and 80 cores on my PC. I was told after a certain number of cores on ANSYS Mechanical the solver does not improve performance (or return solver time) in fact it has...

    Position vs Runout

    ok hum, so position for location yes, but I thought it is also tilt of the centerline. i.e. the cylinder of diameter .003 (shown above) which is the length of the feature, the centerline can tilt within the .003 cylinder, anywhere. So it controls location and "tilt" or perpendicularity? btw...

    Position vs Runout

    ok in conclusion, |runout|0.10|A| = |position|Ø0.10|A| and are treated equally in a tolerance stack. Correct?

    Position vs Runout

    Hum? so if a |runout|0.10|A| means a zone the is 0.10 wide but 0.050 each side? So, its 1/2 the distance? I thought it was total indication? So if you start at 0 and run the indicator and then goes to 0.10 and then back to 0. Does the centerline shift as shown?

    Position vs Runout

    @DDave: I did that. Can't the zone be all in one direction? I'm defiantly no measuring expert, put the gage on the surface, set to zero and rotate. Can't the gage go from 0 to 0.010 and still be to print? My example attached is using 0.100 for ease of viewing.

    Position vs Runout

    @Belanger: Maybe this is where I am wrong? I was always told that when doing a tolerance stack analysis that a positional call out is always 1/2 the zone, and runout is the full zone to be used. If I leave the position to be the same then the tolerance stack will only be 0.005?. A tolerance...

    Position vs Runout

    @dgallup: "double hole movement", what do you mean by that? The OD is datum A which is always perfect. The ID is where the control frame is. Sorry I did not make that clear. my bad.

    Position vs Runout

    Hi all, I need some help clarifying position vs runout. We have a drawing that has a hole in a round part. We call out |RUNOUT|0.010|A| where A is the outside centerline. I want to convert runout to position (position is directional and runout is not), so therefore; it will look like...

    ANSYS 19.2 Combine Force Convergence and Displacement Convergence

    Hi all, I am currently running ANSYS Mechanical 19.2. As I run the analysis I want to view both the force convergence solution output and the displacement solution output on the same monitoring graph (Worksheet) so I do not need to click back and forth between them. Does anyone know how to...

    Thermal Displacement - Bushing into a Housing

    Hello All, I want to calculate the thermal displacement of a pressed fit bushing into a housing. If using the area equation calculation using the equation: A_f = A(1+2(alpha*delta_T). Where, A_f = Final area A = Current area Should I use the cross sectional area of the bushing (I think this is...
