WF5.0 absolute accuracy only?

WF5.0 absolute accuracy only?

Can anyone confirm the rumor... with documentation, that WF5.0 will have accuracy absolute only? If so I'm curious what the default value is? Anyone currently using absolute now ? if so what value ? any conflicts or problems ?

Thanks

Steve

No, Relative seems to be default, at least on Pre-Production. It is now listed in new GUI Model Properties. It's a bit strange. If I change a model that was created with Relative accuracy I can only change the value. However if I change a model created with Absolut accuracy I'm allowed to change to Relative. If I change from Absolute to Relative I'm also allowed to change back to Absolute. This gotta be a bug. See attached pics.

I've worked with absolute accuracy pretty much exclusively for the 12
years I've used Pro|E, with few issues. In fact, I tend to have more
issues when I use a client file with relative accuracy. We use an
absolute setting of 0.0001".

Absolute can slow regen times if set too tight, but I've found it to
result in more robust and predictable models. With relative accuracy,
the effective accuracy of the model varies with the model size. If
during development, a model changes size dramatically, features can fail
unexpectedly.

For example, say the design is simplified and two parts are combined
into one. You open one model and insert early into the model tree new
features to expand the part to include the geometry of the other.
Because of the increased model size, the effective accuracy of the model
is increased. That means the smallest allowable edge is larger and
later features like draft or rounds which created small details are no
longer within the new accuracy limits and they fail. It can be
maddening to try to figure out why.

The flip side can be true as well. If a model gets dramatically smaller
by changing early features, the smallest allowable edge is decreased and
now rounds may regen differently, creating smaller detail than was
allowable before.

Thanks to all that replied! Turns out PTC will NOT have Absolute Accuracy in WF5 as the default, it will remain untouched but they are looking at this for future releases. Absolute Accuracy seems to be the way to go when using Pro/NC.

All:



I am trying to dimension a 3d Isometric view. Pro does indeed creates a
dimension, however, it is not the correct value. I have allowed 3d
dimensioning in my config file, but does not have any affect. What am I
missing?



Thanks
