1. .crc error: how these errors occurs, where will you search for this kind of errorandhow will you rectify.


2. hole table: suppose a costomer gives me his own hole table. how will i use that table instead of default hole table?


3. in GD&T why datums planes are always named A,B,C........... why not S,W,G,A.........?

2. I had something similar to this before in the forum, I'll see if I can find it


3. ISO standards are that you begin naming and labelling (whether it is detail views, section view or geom tols) at A and work your way up. That's what happens when you are tied to the English language (

). There is nothing to stop you naming items in a different manner, but it will be confusing to others who will be used to the standard naming conventions

Sanjeevkar1,
Circular references are just what they sound like. Part A references something in part B that references something in assembly C which references something in part A. The references are in a circle and Pro/E has a hard time resolving them as they go around the circle.

you can put the hole table file in with your other hole tables pre-loaded with ProE, then when you place a hole feature that hole table will be available in the drop down list.


Should be somewhere like this C:\PTC\proeWildfire3.0\text\hole

To understand circular references...


Open an Excel sheet..


In cell..


A1> input "A"; A2>input "=B2+2


B1>input "B"; B2>input "=A2"


Read the error message that Excel displays and if necessary read the help.
