I’m jumping in right now to play around with synchronous sketching, and I’m finding something I’m not too impressed with. Is this Matt-the-Noob ready to learn something new? or is this a weakness in the tool? Watch the movie and tell me which it is.
Update: Ok, this is from Dan Staples. Dan says that yes, there is a dependency there with a certain direction, but that is created by the relationship added.
So instead of trying to do this with synchronous sketches, let’s try to do it with ordered sketches and the BlueDot. This actually works. You wouldn’t think that ordered would succeed where synchronous fails, but its true in this case. …that is unless some of this is operator error, which is entirely likely.
If the presentation of this information looks scattered and fragmented, that’s because I’m trying to learn something at this point, rather than trying to teach something. I’m just letting you follow my disjointed learning process. Let me tell you, trying to write a blog while you’re learning a topic is harder than it looks. ;o)
Ok, so after all this failure, I’m starting to feel pretty comfortable. I try to trick the software now. We’re getting into familiar territory: workarounds. I’m not confident yet in the sketcher, but I’m sure this will change. I’m pretty disappointed that even within Synchronous mode, you still have directional parent/child relations. I thought this was the whole point of synchronous, to get rid of these.
Anyway. Here’s my workaround attempt. I make the two splines again, and I’m more careful about how I draw them. I’m learning. Action-object. I can’t seem to make object-action work in synch sketches. I constructed this sketch, thinking I could game the system a little. I create an offset plane, draw the circle on the plane right above the origin, then draw 3 pt splines on the other two perpendicular planes, with the mid points of the splines at the center of the circle. I thought then I’d be able to just move the circle to get the two splines to expand. Still not getting that one to go.
Here’s what I’m expecting: I’m expecting to be able to pull up the middles of the two splines at the same time, regardless of which one I’m editing at the time. I’m expecting that synchronous sketches in SE will work just like a single 3D sketch in SolidWorks, except that everything will work the way its supposed to. 3D sketches in SW are notoriously buggy, but the concept is perfect. If this were solid geometry, Solid Edge would be able to make the edits perfectly, but it can’t manipulate sketches? If I understand this correctly, then there seems to be a disconnect. I guess the idea here is that sketches are throw away items, but it doesn’t account for what I’m trying to do with driving ordered features with synchronous sketches. You just can’t get there from here.
Maybe I just can’t let go of the idea of driving 3D with 2D. Maybe this situation would never really come up in the world of things you actually do in SE. I’m definitely expecting the 2D parametrics to be as good as the 3D parametrics. Where would I use this?
