Sketcher Regen Hell!

[treddie]

Howdie.

This one is killing my brain! Please HELP!
I have been trying to solve this problem for three hours with no success.

I am building an architectural building in Wildfire2. I created a plan view in sketcher for all of the grounds parts (walkways, pools, grass areas, etc). I thought it would be quicker if I just included all of the grounds parts in one master sketch file. Then, when I needed any particular part, I could just open this master sketch and trim/delete anything I didn't need, regen and extrude, walla! Done!...
That was the plan at least. But I keep getting the following errors:

WARNING: Not all open ends have been explicitly aligned.
Cannot have mixture of open and closed sections.

There ARE no open ends! There ARE no open sections. I have gone in to every node and checked it, and overdimensioned till I'm blue in the face, to no success. I have searched for extra open paths hiding underneath something, but there are none. Will I have to align the points at EVERY intersection?! That's a hell of a lot of work. And I can't exit sketcher in the hopes it would regen anyway; doesn't work.

HELP!!! I'm drowning!
TIA!

Try triming the lines at the intersections. There may be areas where they are not intersecting, even though it appears that way on the sketch. If that doesn's work. Try to rebuild the sketch using relations such as point on entity, tangency ect. If done correctly this will force the sketch to be closed.

Thanks for the reply. I think you are right; I just got it to work before you emailed me, but my solution was only made possible by the fact that the imported sketch was over an existing extrusion which provided points to align to. Once I aligned all alignable points, it regened and extruded fine. Then, to get rid of the dependencies on the existing extrusion, I went back in and removed all references to it. It did'nt question the lost references once I removed them, so I could safely delete the existing extrusion when I was done. But without that underlying extrusion feature to reference to in the beginning, I think I wouldn't have had any choice but to do what you suggest; force point on entity at every intersection through a relation. I'm curious if SolidWorks has the same problem. Sometimes I waste so much time trying to repair ProE issues.
Thanks again,
treddie

I get this sometimes when simply using convert edges to sketch entities. Especially on circles, which I know are complete. It sometimes doesn't think the ends are closed. (Pr/E makes it two arcs for some reason.) Instead, now I just draw a circle over the other one.

i think it is against proe principle to make sketches too complicated. Most probably it would have been faster if you had built your sketch in simpler sketches. It will make easier to redifine if you decide to change something later on.

Yah, sometimes ProE just does the most inane things that can tie you up all afternoon. Joe, I took your advice; better to keep things simple. But even if I do a simple sketch, the moment I start trimming things, my references all seem to get screwed up, and those damn messages keep popping up. I did a Geom Check and DID notice some issues. I'm going through those and seeing if I can sort this thing out.

I agree with joe.
In Wildfire you can now name the feature seperately in your model tree, so a more manageable solution.

Do you model your plan as a "true" Pro/E skelton, or just a part with curves.

For TDD I have often wondered how to model a house. I have done a few plans of my own, but never spent enough time to sort out the best methodology.

If you are doign it professionally i reckon there could be some nice ways to work.

Cheers

"I have often wondered how to model a house...."

Dave, take a look at SketchUp. Great for modeling things like a house or simple little woodworking projects. And its free. No parametrics or TDD though

If you need to move a sketch, turn off the intent manager first. It assumes lots of dimensions and does things to the sketch that are undesireable.

Without intent manager on, the sketch is as it is meant to be...not how Pro-e thinks it should be.
