How Is This Even Possible?

Anonymous — Fri, 31 Mar 2017 15:50:24 GMT

I've been tearing my hair out for the last houir trying to get this sketch to behave, and I don't even see how what I'm seeing is even possible.

I have a "global" sketch that defines some critical dimensions. Some lines from this global sketch are projected into a sketch in one of the components. Though the lines are where they should be, and they do create numerous closed paths, only SOME of those closed paths are recognized as such. In desperation, I added several random lines to break up the problem area, to try to find where the actual problem is. The result is below, and has me really scratching my head.

In the screen capture below, I have selected (highlighted in blue) ALL areas that I possibly can. The remaining pink areas, even though CLEARLY closed paths, CANNOT be selected. How is this even possible, given that, for many of them, ALL of the surrounding areas are recognized as closed, to the surrounded area HAS to be closed, yet is not recognized as such.

The design file is below, the sketch in question is the first one in the Control Panel component. The "global" sketch is "Sketch->Global Features".

Something else I'm finding, though I'm fairly certain it's just a display glitch - If you zoom all the way in on one of the endpoints of the radial lines which end on the any of the large circles - these points are all constrained to be coincident to the circle, yet when zoomed in, they do NOT lie on the circle.

And, on a few related notes:

1) If you have two sketch entities that lie on top of each other - for example, I have a construction line, then draw a shorter solid line on top of the construction line, and make them co-linear - HOW do you select the shorter line? The longer line can be selected by clicking at any point NOT under the short line, but I can fine no way to select the shorter line other than a window selection, which isn't always practical. Sometimes I get a dialog that lets me seect which of the "stacked" entities I want to select, but that RARELY happens. Shouldn't there be some kind of "deep select" command that forces that dialog to appear??

2) When you have several constraints on an entity, how do you determine WHAT constraints are actually there? There are often so mny constraint icons shown that it's impossible to tell which ones belong to which entities. In Solidworks, I can click on an entity, and it will SHOW me which constraints are applied to that entity by putting up a dialog listing them all. I can then click on an entity in that dialog, and it will highlight the entities that constraint applies to. I see no similar capability in Fusion.

3) When I select an endpoint, and right-click, I often get an option like "Delete Coincident". But, if that endpoint has more than one coincident constraint, I have no idea WHICH one it will delete! And, it seems to sometimes give me that same option, when there don't even appear to be any such constraints applied.

As if this were not already bizarre enough.... I went back into the sketch, and I CAN select all those areas, eventually... If I zoom in, zoom out, move around, click in different spots within those areas, eventually I'll find the right zoom level, and right location to select them. HOWEVER, if I delete all the "debugging" lines, no way in he11 can I select that triangular area in the center of the screencap....

1) "Sometimes I get a dialog that lets me select which of the "stacked" entities I want to select, but that RARELY happens. Shouldn't there be some kind of "deep select" command that forces that dialog to appear??"

Just press-and-hold mouse button in the place of overlapped anything. And that "deep select" dialog will popup.

2) You can use this method: switch off "Show constraints" checkbox in sketch palette. Then click on a curve/line - it will show constraints applied to it.

Reverse action is more reliable. Hover mouse (or use "deep select") on the constraint - and corresponding will be highlighted.

3) It will delete all coincidence. If you do "deep select" on that point, you will see several curves, that have the end in that place, and just a single point. After the deletion of coincidence in the same place there will be the same number of points as curves are there.

As for main problem... I've'opened the file you provided, found that area and could not see any issues. All profiles (closed loops) are recognized as expected. Did you try to restart Fusion? Because I also faced with strange profile/faces recognition several times And restarting the application helped.

Ah, ok, it's like Windows. If it's not making sense, reboot. That did fix the problem, after wasting an hour....

Thanks!

While the reboot fixed the problem for now, that still means there is a bug somewhere.
