Pushpull won't cut window indouble surfaced wall
-
Upgraded to SU7, and I'm having some difficulty.
Normally my workflow consists of taking dxf/dwg of ACAD files, and bringing them into SketchUp for modeling. For this particular file the dxf was a 2d drawing, which I cleaned up, put on another layer, traced the interior and exterior walls, and pushpulled them up. Using the dxf reference for window placement, I usually create window rough openings by placing a rectangle on the exterior wall face, and pushpull the rectangle though both the outer and inner wall faces to create an opening in the wall, where I later place an appropriate window component.
After the SU7 upgrade I seem to get walls that won't allow me to do this.
Attached is on such wall. Could someone have a look at the .skp file, and tell me if the problem occurs for them as well, or if there is something I am missing.Thanks
PS: The opening that is beside the rectangle I created by making a corresponding rectangle on the inside wall face and deleting it, this is just too much work.

Hi Dale,
The two faces of the wall aren't parallel. You need to have two parallel faces for the PP tool to cut the other opening as well.
Have a look at tha attached version of your model; I didn't change anything but set the axes along one of the edges of the wall and changed the style to display edges by axis. The black edge on the other side of the wall indicates that the two edges are not parallel - thus the two faces aren't either.

Thanks once again Gaieus. I should have suspected that, as most Cad files have problems with parallel and joints etc. Thats 2 today. I'm going to have to owe you a beer on this.

Okay, Canadian beer is fine.No US beer tho
-
Woah now... what you got against US beer Gaieus?
-
Just for you then....

It's all about alcohol content
Not only... I'm not Canadian but let me quote a Canadian saying: "American beer is just like making love in a canoe - f*ing close to water..."
-
Ahhh yes... do you really think that most Americans care about taste when all they're trying to do is get drunk off of it anyway? Now I have a couple friends that won't drink American beer so they go to these specialty stores to get beer from over seas but I don't see why anyone would want to pay that much for 'good' beer. I'll stick to my Budweiser, hasn't failed me yet!

Personally, I prefer my 'bud' in a different form.Now, this is scary...I'm stickin' with java.

Dale, What is interesting is that you are having this problem after you switched from v6 to v7. Did you change anything about the way you built the model that produced the dxf? If so you might be able to find a solution.
-
I have noticed this problem since changing to version 7. The dxfs are exported from Cycas. I never had the problem with v6, but I've noticed it recently on the occasional wall. Could be a rounding issue with the dxf importer? just guessing.
-
Have you tried to import this exact file in SU 6?
In fact the "inaccuracy" is rather big in this case. -

Is the drawing located near origin, or is it drawn with world co-ordinates? If it's drawn in world co-ordinates it can cause problems for SU with inaccuracy. Whenever I import at dwg or dxf into SU I always make a copy of the dwg/dxf and move everything I want to the origin and do a purge and audit in AutoCAD for safe measure.

to get back to the original topic of this thread
Gaieus, how strong is the average beer in Hungary? I ask because I once heard that in Germany a beer is considered 'non-alcoholic' when it contains less than 0.5% of alcohol, whereas in Russia a beer with up to something like 5% is still 'non-alcoholic'.
now Hungary is about halfway from Germany to Russia. so I expect your beer to be quite strong. and therefore one Hungarian beer is equivalent to a lot more Buds... -
Well, the "weak", local lagers start at about 4.8-5%. Weaker than that doesn't even deserve the name "beer".

Hear hear!

I want to make it clear that excess beer consumption had nothing to do with my inability to cut the window hole
However, I was corrected by someone , who directed me to this sitehttp://www.fermentarium.com/index.php?option=com_content&task=view&id=291&Itemid=56
Which has an explanation as to the way American and Canadian beers measure their alcohol content and this chart:

Now, as for the dxf.
Although I have found SU7 to be rather glitchy, I don't know if I can blame the problem on it. This dxf is from a colleague who actually uses Sopftplan, and to be quite honest, was one of the best dxf's I have received in terms of what had to be cleaned up in order to get things functioning well in SketchUp. The AutoCad drawings I get usually require a hell of a lot of review to be sure that walls meet, and are @ 90, or 45 degrees etc, etc. With them you should actually hook the computer directly to a 200 amp 240 volt circuit so that the "weld" ruby has a chance to work.
Partially though, that is because of the abilities of the person creating the file, as one colleague used to say "Garbage in, Garbage out".
Most of the walls in the file I had no problem with. The wall that gave me problems was on a 45 degree angle,if I remember correctly it was joined right at the corner with an interior wall that was a different thickness (2x4 vs 2x6), and probably the original Cad file joined them with this little discrepancy intact. Attached is a preliminary clay rendering I did of the file yesterday afternoon, so you can see that it worked out o.k.
-
I agree with you, Dale. most problems with dxf files occur, because the person drawing it didn't have a clue of the snap-modes of his software. therefore many lines are simply not joined at corners.
but one has to admit, that there is no program in the world (at least to my knowledge) with which it is as easy to actually join vertexes as with SketchUp with it's automatic snap modes and superb inferencing engine! and that is why we all love SketchUp!
