Hi, I'm Talchi.
I'm in trouble, for datum surface is extremely large.
On "Model tree", When I play a certain feature, datum will be very large.
(30 times the size approximate model)
I have tried to remove the features that were the problems seem,
I did not reach resolution.
I think, invisible features ( such as cross-section for the sketch ) are causing a problem.
It is not known details.
I'm sorry poor information,
Please help me to solve this problem.
My environments is below.
Are you talking about a datum plane, like a default datum plane or one that was made? If so, select the plane, right click edit definition, display tab, select the adjust outline check box, select size and then you can tell the plane how big it is in your units.
if you cannot give us information, then it is not possible to understand your problem.
In case of Datum Plane you can modify the size of its outline - simply edit its properties.
I've prepared the image.
It may not perfectly meet the requirements.
I'd appreciate it if accustomed to assist in resolution.
I remember a problem in older version of Pro|E. We could not figure out what the issue was and often remodeled the part when the problem surfaced.
In Creo, you can permanently resize the datum plane and axes as part of the datum feature. However, this does not solve the screen zoom/refit issues.
If you unblank all layers and show axis, datum points, and planes is there an item that shows far away from the part?
I have seen parts where some small item that was to be a small decimal value with a number of digits is accidently given the value without decimal: 0.125 -> 125.
Also, wrapped datum curves will leave the extents set to match the curve, even though the finished part is very small.
Is there an external reference to an assembly level feature or to a skeleton?
You should be able to resume features one at a time and determine exactly which feature is the one that causes the datum planes to resize.
if your model contains datum geometry located at great distance from solid geometry, then I think you can only:
1.] create additional zoomed view which will be used instead of Default Orientation view
2.] turn off (i.e. hide) Spin Center ... mouse cursor position is then used as the center of rotation
