My STL created in sketch up '15 is starts out good, but then

jstone33065 · Post by **jstone33065** » Tue Sep 01, 2015 6:48 pm

ok i created something in sketch-up 2015 and the model looks great when i'm getting ready to print it in matter control...

but as the title to this thread insists "My STL created in sketch up '15 is starts out good, but then" ugh what a pain in the walnuts!!!

well i don't think its matter-control per-say but im still new to this...although i gotta say so far i put almost 200 hours on my rostock max version 2 and even with having to do minor re-calibrations now and then its still kickin ass!

the only time i really have a problem is when i am printing something that i created...usually its a fix in sketch-up, something simple like forgetting to group everything or forgetting to intersect all the lines but this is weird cuz its started to fill in a spot that should be empty and the model in mattercontrol doesnt show anything in that spot as well...
any ideas anyone?

It's printing where a hole it's supposed to be? That seems like an open object issue.
Post the STL if you can.

thanks for checking....bye the way, is there a way to upload a pic without having it hosted beforehand?

I opened it up in Repetier. you need to flip the faces inside the channels to start. just select your whole model and normalize faces.

how do you figure

so in sketch up i need to just normalize the faces and thats it...

i wish i could upload a pic so that the problem could be seen

thanks.

because of how sketchup handles materials, it has a front and rear face. if there are any rear faces showing it can screw up the print. Repetier warns you of this

You could probably repair it in NetFabb. It says there are 26 shells and 29 holes, so it's not manifold as is.

Try this instead.

ok so i reversed faces and regrouped and exported...so please if you would let me know what it says in repetier if you would please...
thanks

Just use Jim's copy above. As for your copy, you reversed all the faces and now all the good ones are flipped. Here's a Tip. When your in sketchup, turn off textures so you only see the default white surface. If you rotate around your model, the bad faces will show up as light gray/violet color. I do most of my work in sketchup as well, and I've had to learn all the oddities. Also for future reference, don't have two solids meet at only one edge. You did this at the bottom where the channels meet the base, and that was likely one of the things throwing it off. it's a problem unique to how sketchup handles its exporting.

Jimustanguitar = thanx im tying the one you fixed right now....ultimately i would definately like to figure out how to figure it out myself because SEBRET, when you say that "all i did was reverse the faces so the good ones are flipped"....the thing is...the misprint happened across all of the boxes as it was getting done with the upper bottom corner where it meets with the back wall of each box...it just started creating a layer of PLA across horizontally like the floor of each box was there....
SEBRET = when you were talking about the bad faces being a different color...yeah i do get that but in addition to that i would get (if i were to try and select a bad face) a distorted face when using something like the push/pull tool and not be able to use that face until i zoomed in or redid the part totally. i.e. when selecting the face it would highlight but the face would look like it was on a totally off angle from the spot that it was supposed to be in from the first place.
but yet when i clicked on each face of each box in this model i get no such effect...so would you be willing to give me an idea on how to undo what was done...i would definitely appreciate it...
i apologize for my inexperience as this same issue has already claimed more than a few of my projects leaving me at a loss for a huge amount of PLA

thanks....

jstone, I'd take a serious look at DesignSpark Mechanical if you're a Windows user. The sketch workflow is VERY similar to what you're used to in Sketchup. It's free to use and from what I've been told, spits out pretty good STL files.

It does generate great STLs. I'm working on a video tutorial as we speak. I'll post the first installment in the next week or so.

jstone, I'll agree with these guys. There are a bunch of better tools for the job out there if your willing to give them a little time. As for the current model, short of walking you through it, i would suggest starting fresh and watching all the tips and tricks vids google has. I still use sketchup for my stuff, but that's partly because I've never pushed any extreme geometric bounds, and partly cause I've already invested time into cheating its kinks out of my work flow.

jstone33065 · Post by **jstone33065** » Wed Sep 02, 2015 4:17 pm

well im definitely not asking you to walk me thru it....just this one problem is really bothering me and as for other tools..as long as they are free im for it...but sketch up has tons of plug ins/ extensions that make stuff really really easy...

Also, Geneb thanks for the heads up and i only have 1 question about that...is Designspark mechanical a browser based application that requires open webgL cuz if so then im screwed...RAM memory issue + NO CASH = me! WooHoo 4 meeeee !

i really wish that i could upload a pic so you can see what im talkin about...when i printed out the file that Jim fixed for me, it printed perfect...so of course i imported the stl into SU and wouldnt you know it after i mirror imaged it and exported to stl to print....lol

BTW Jimustanguitar = THANKS AGAIN FOR THAT...MUCH APPRECIATED!!

it did it again!!!!! someone shoot me now...hahahahaha

so how about an idea to upload a pic without having it on a server...
i noticed you uploaded a pic earlier Sebret...is there a size limit to the dimensions...something simple that i couldnt find anywhere when i looked for pic guidlines...lol
i dont do websites anymore 4 so i dont have an ftp site anymore....

anyway looking forward to the feedback and/or solution
thanks,
jstone

It's a standalone app. Browser based cad tools are a gimmick at best and a joke at worst.

Knock knock. Who's there? OnShape. Onshape who? OnShape-ya glad you didn't try Fusion360?

Is designspark free to use for businesses?

Post by **geneb** » Wed Sep 02, 2015 8:08 pm

As far as I know, it's free for any user at all.

////////////seriously...i tried it after downloading the free version...it seems easy but then the repair feature freeks out or i just really am clueless at what i am looking at...
as well as the free version doesnt let me export as stl////////////

MY BAD...I FOUND IT....FINALLY...I CANT SIT TOO LONG CUZ MY LEGS AND CIRCULATION ARE MESSED UP...BUT YES FOUND IT AT 3RD SIT DOWN...

THANKS FOR THE INFO JIM!

(Please forgive the XPosting, I'll create a standalone topic for it, but wanted to drop it here since we already talked about it.)

jstone33065 · Post by **jstone33065** » Fri Sep 04, 2015 2:06 pm

regardless of what the rules say...i dont mind at all....and because we were talking about it..newbies that come across this thread and do download it should definitely be able to come back here to where they know they can view the tutorial and use it..
but as for me i wont be able to use ds mechanical cus my machine doesnt have the right video card..or a good enough one i should say...but 1 day soon...muhahahahaha then the world shall be mine..lol

but netfabb = awesome time saver for fixing all stl's after so much work goes into it..
i hereby claim that all stls big or small should go through the wash with a little netfabb detergant to wash those holes right out of your hair...lol

but seriously, im aint joking!

again, thanks for that!
