NX7.5 Assembly Show Hide Datums, curves ect. 1

[SDETERS]

We are new to NX. Coming over from I-Deas. In I-deas we had display filters so when I set to show only assembly parts and reference planes in an assembly that is the only objects that showed up on the screen. One could hide and unhide parts, sub assemblies all day long and this was the only objects that showed up on the screen.

In NX I am experiencing different behavior I am sure there is an easy solution but I can not find it. When I use Show/Hide in a NX assembly I hide all of the datum planes, curves ect. but when I hide a couple parts in the assembly then I select the assembly to show all the parts, all of the parts show up plus all the parts geometry curves datums ect. show up again. What is the proper way to set the assembly up so I only get the coordinate systems with the solid bodies to display in the assembly? We are using the entire part reference set in the assembly.

Try switching to the model reference set or make a custom reference set that only contains the solid body and the coordinate systems/datums that you want to see in the assembly.

So in the prt file of the part we can set up different reference sets. Is This an ok best practice? I have read in different places setting up reference sets in the assembly prt file is a bad thing. So I was wondering about setting up reference sets in the part file. The problem we are also running into we are using the JT files from I-Deas and we can not set up reference sets for these files. Would layers be a good solution for this? Thanks for the feedback.

Reference sets in individual parts is the recommended way to control what is visible in the assembly. Some parts are not easily placed in the assembly using only the solid body, a compression spring, for example. In this case, you can make a reference set with the solid body and a few select datums to make positioning easier. Once constrained/positioned in the assembly you can switch it back to the reference set that only contains the solid body to clean up the view.

The problems arise when you start using reference sets in an assembly file to try to control assembly configurations. This is a holdover from the days before assembly arrangements and some of the other recent assembly management options. Imagine you have a main assembly with several sub-assemblies that each have several reference sets that you have to change individually to control configurations, positions, etc. It is confusing at best and can cause problems down the road.
