Does anyone know of a way to make feature control frames not interfere with dimensions when they are snapped into position on a horizontal dimension in PMI?
If you place a horizontal or cylindrical dimenion in PMI and want to put a seperate feature control frame under it, it will snap into place and have the lower extension line going through it. You can resize your extension lines by dragging, but not individually, so the upper has a giant gap. Any ideas?
What version of NX are you using? If you're using NX 10 you can add jogs to the individual extension lines for the horizontal dimension. Is there a reason why you can't place your dimension outside of the extension lines so that t he FCF does not interfere?
WARNING: Creating a PMI feature control frame (FCF) using the Annotation Editor is not a recommended practice, especially if you intend to reuse the PMI in a downstream application. Each PMI object type contains specific information that is processed by downstream applications. If you create an FCF using the Annotation Editor, it shows up as a PMI Note object (instead of a Feature Control Frame object). You can see this by examining the objects on the PMI node of the Part Navigator. The PMI Note object may not be correctly interpreted as an FCF object by downstream applications.
It looks like we could benefit from the "Scope" option including the "Text to Line Gap" Setting option. This issue was reported and converted to an ER (6253817). The ER requests that the dimension line be trimmed to the FCF when stacked on a PMI dimension. I just checked, and this does not appear to have been implemented in NX11.
While Drafting has an option to insert a GAP (user defined symbol) on an FCF created as drafting annotation (non-PMI), it does not work on inherited PMI (whether inherited in the view or on the drawing sheet). If you're dimensioning in Drafting, and you really must have the FCF stacked this way, you could keep the PMI in modeling and recreate the dimensions in drafting using the GAP symbol to trim the dimension line. The only workarounds I see for PMI dimensions inherited in Drafting, or in Modeling, are to edit the Text To Line Gap - which leaves the giant gap at the top.
Another "work around" I have used is to align one of the datum separator bars in the FCF frame up with the dimension line using the select origin tool. I do not know if this works with them PMI. It works in 2D. This may be a little bit more robust for downstream solutions. I do not know if this associates the FCF with the dimension like the stacking does??
In NX 11, you can double-click the dimension to edit it and drag the arrow heads shown in the picture above to adjust the dimension line gap. It adjusts both sides so it ends up looking off centered, but at least the line isn't running through the FCF.
Unfortunately this doensn't appear to work for basic dimensions.
