In the feature who support the "sketch region" filter, there should an option of select and deselect the specific selected and non selected region. Which help in to increase productivity.
I fully agree, sketch regions to be really useful need to be further improved to allow parametric selection and deselection, even after there are errors when the sketch is modified.
Currently, the algorithm of the sketch regions uses the regular sketch and trims it on the fly, but does not preserve the selected region loop in the feature selection box to allow the user to later unselect, or redefine the regions. The regions should be selectable as an alternative to using a sketch in the extrude command, and not as a way to convert the geometry to a regular sketch. This current implementation only speeds up feature creation, but not feature modification.
I could not see the videos kamleshojoshi, I only noticed that the sketch regions does not work as other CAD software, it does not keep track of the selected regions, it only adds an algorithm to automatically copy the entities selected from the external sketch, and automatically trim the crossing lines or arcs. It does not register in the Extrude command the loop, or selected region that the user selected, that's why when the external sketch is modified, it does not allow easy selection or de-selection of the initial selected sketch regions, the user has to manually reference the external geometry sketch lines, arc, etc, and manually re-trim everything again.
I think the sketch region filter option should be added inside the material addition or removal command like extrude, sweep, revolve and many other so that the selection will be added to the feature. like selected contours in Solidworks.
I noticed there are lots of functionality added to Creo added in a version, that gets half-baked and does not get finalized in terms of implementation. Sketch regions is one of them, Multibodies from Creo 7 to Creo 8 also did not improve much, user restricted parameter tables, also, there is no UI interface to add those parameter tables, they only can be added in an external restriction parameter files, that only gets loaded when Creo starts, and for which the documentation is awful, and lack a variety of examples. There are features in Creo that are the best that can be found in any CAD package, such as the Edit References and Replace References funcionality which should be praised for the time that it saves Creo users, but there are other features that Creo could be finished instead of being left up partly implemented.
I agree with you. The selected countours should be saved in the feature, as an alternative to the internal sketch. There should be added a field to register the countour index or number that the user selected, or maybe a point in 2D space where the user clicked to define the initial selected sketch regions.
Voted. I saw some PTC posts about sketch regions and used it for the first time just now, thinking it would save the hassle of having to trim multiple enclosed loops in sketcher. About 10 minutes after creating my first feature with it, I want to add an additional region, alas it looks like that can't be done.
Complete waste of time, I'll ignore sketch regions until it's actually useable and parametric. The workflow of changing the selection filter and then driving a feature from there is ridiculous compared to selecting regions from inside the extrude/fill/revolve/etc tool rather than having to select the region first and then open the tool.
I'm no fanboy of SolidWorks but make region selection work like that!
Same here. We don't use sketch regions for the same reason. To be useful, it must be possible to Edit (add or remove aditional regions as needed).
It would speed conceptual work, increasing productivity, but for that to happen, the Features that consume the Sketch Regions (Extrude, Revolve, etc), need to parametrically select and deselect the regions, not as PTC currently implements it, converting the regions to loops that are automatically trimmmed once, and treated as regular projected wireframe entities.
