I have a problem:

I made a feature of protusion and successively a lot of other features, that's cut and extrude, but when I want to modify initial protusion I can't....because is a read only feature...

Someone could help me: I will be to him very grateful.



Thank you

Bye

Read Only features are applied to a PART such all the features previous to one feature that has been assigned Read Only will not regenerate. Often people will have a part with repeated geometry (i.e. 300+ general patterned table driven holes) that markedly slows down the performance of a PART. Now when that PART is used in a next assembly, the performance of the assembly slows too. When the features in the PART are reordered such that Read Only features are first and other features that are still deired to be modifiable and later, then using Read Only in the PART allows the part to skip past the features prior to the Read Only, and only regenerate the features in the PART after the Read Only. Sometimes, Pro/E users will simply apply a Read Only feature to the last feature and lock the entire part. That works, but EVERY time you need to modify geometry, you have to Clean the PART model of the Read Only feature. (you might then also re-apply the Read Only feature after finishing the modifications...) It does not affect viewing the model, or even changing parameter strings, or simplified reps, family table instances, etc, but it does allow a part that might take several minutes to regenerate, that is not apt to change, to dramatically improve to only a few seconds regeneration time. Try it.



I would not suggest setting a precedence for saving PARTs with a Read Only feature applied, but for that frustratingly slow component in your bigger assembly(s), going into the slow part and adding the Read Only to the sloth like PART may give you immediate satisfaction. This is an option that may work better than substituting a Simplified Representation of the PART .



I have highlighted PART several times here because the Read Only functionality is ONLY available in Part mode.

hello, proe users



let me add my opinion to this nice conversation. As I know read only features can be created in part mode, assembly mode (assembly features such as hole, slot, cut, pipe) and in drawing mode can be used if someone changes the following option in config.pro :

draw_models_read_only, if you set this option to yes, the drawing model files are read only (i.e. they cannot be modified), you cannot add driven dimensions, geometric tolerances, or similar items to the models,

As someone can see there is an option in config.pro : regenerate_read_only_objects, that can be used, as config.pro describes, whether an object fetched from an Intralink database with blocking status can be regenerate in a Pro/E session.

According to my opinion, read-only features are not very flexible features when someone uses them in purpose to reduce regeneration times in big patterns. I don
