I think there is an icon in product design that enables you to view sections through the assembly but I can not find it. Where in the menu can I find it? Can some one please post the steps to go though to see through an assembly? I appreciate your help.
does anybody know of a good online source or tutorial for catia? My help is not working and I can not find clear instructions on how to do stuff by searching the forum.
Thanks
You can specify the tolerances for both outer and inner diameter and a tolerance for wall thickness as long as there are ranges that all three are valid. The tolerance for thickness will be a limiting value for one diameter with respect to other. This is not a contradiction or over constraining.
When I try to zoom, it is the tree that gets zoomed. The focus of my zoon commands is the tree and my rotate button is disabled. How do I return the focus back to model? Thanks
If these definitions, can somebody tell me what constant and variable mean? Thanks
1. Virtual condition - A constant boundary generated by the collective effects of a size fearures's specified MMC or LMC material condition and the geometric tolerance for that material condition.

The difference between profile of the surface and profile of the line is similsr to the difference between flatness and straightness applied to a surface. If flatness tolerance is .2 then the whole surface must be between two planes that are .2 apart. If, on the other hand straightness with .2...
ringman,
Thank you for responding. The test is from a text book by E. Max Raisor. I thought about this and .002 is the right answer. The reason is that the standards, rather arbitrary, distinguishes between when the control is applied to the feature (that is the surface) or feature of size...
As in flatness and circularity, there cannot be material condition modifiers on run out. You can have datum references in run out thought while you cannot have datum references in flatness and circularity.
You can loosen up the tolerance on the diameter to cover the full range of value and control each individual shaft by using straightness control. Since straightness of the line elements of the surface refer to the parts true geometric counterpart, the vairation within each individual shaft is...
Heckler,
Thank you very much for your response. I don't agree with some of the points you made. Below, I quote from you message(the text in quotaion mark) and add my comment below them:
1. "You can apply Straightness as RFS or MMC"
This is true only if the staightness is applied to the...
I ran into a quiz about the straightness control. I can not understand one of the answers. This is a simple quiz. I illustrate it below (with question and answers separated in case you want to test your selves) The quiz shows a bar with a diameter of .495 and tolerance of +/- .005 (So MMC is...
Hi,
I am reading an article that describes the resultant boundary condition. It says for an internal feature of size controlled at MMC:
Resultant condition = LMC size limit + geometric tolerance + size tolerance.
For example for a .511 +/- .003 hole with the following Feature control frame...
ewh. There is no need for apology. I very much enjoy this kind of discussions and benefit from it in educating my self. I think we need at least four points. 3 points to define a circle and 1 point to hold the part axialy. I think if we have 4 special points we can seat a cylinder on it so that...
