How can this "bug" be fixed?

[Anonymous]

I get 2 kinda transparent black lines on my model and there's some solid sticking out of the edge. How can this be fixed?

Hi.

It's not a bug.

You have use the tool Stich to create a solid, but you have created a zone to 0 thikness (not a good practice).

You have to be very careful when making surfaces in Inventor.

It's not forgiving at all.

And if you're reusing imported surfaces, that's even more difficult to work with.

Haven't I created a stitch for all the patches? Could you please explain more. Maybe an image would clear it up for me.

I understand but how would I else do the front since I can't use for example the Loft operation because of the edge that is angled. Do you have any suggestions?

I'll clean this up and send it back to you later. I'm tied up at the moment so a day or two is in order.

Omg that would mean the world to me seriously!

Here's an update, i did something different on this file but now I have to think of a way to stitch the light edges together if that is too much ignore this.

Ok,

Cadman is right. Inventor is touchy on creating patchs that are to be converted to solid. It's a calculating thing.

Oh, I see. Since I didn't know how to create that front with only 2d sketching and extrusions I had to use 3d sketching again. I did the whole vehicle with only 3d sketch a week ago but since I couldn't use dimensions on a drawing on that model, I had to start from scratch and try with only 2d sketching but I couldn't do that with the front of the car as you can see.

Here's my older model that I did with only 3d sketching basically, now I just use it as a template to complete the "BACKUPPP2" file to see where I'm at, kind of.

Sorry but my Inventor version is too old to open your files.

I use Rhino3d for surfacing (non-parametric). The thing about Rhino is it's got quad-meshing now which is excellent for scan data processing among other things.

Another excellent surfacing software (parametric & direct-edit) is ZW3D. If you do a lot of that kind of modeling, you may want to consider using ZW3D instead of Inventor. I personally don't own a copy of it, but used it in the past to do scan processing and some surfacing. It still lacked some features that I wanted, which is why I never made the switch. For example, it can't make press-break sheetmetal for flattening. You have to make them manually. But maybe they added that function since I used it a few years ago? Otherwise, it beats Inventor by lightyears for organic surface modeling, plus it's parametric and has direct editing. Very nice software!

Thats interesting, thanks i will look into it for sure!
