Struggling with Mould Split using Boundary Fill and Surfaces

[Anonymous]

Hi

I've been struggling to get a mould to split using boundary fill and the surfaces formed out along the split line of the part.

The screencast goes over the problem and I would appreciate any suggestions to fix and get this to work, as I've been working on it for the last 5 days and I'm stuck at the moment.

Thanks

Richard

Still working out how to link the screencast!

If anyone is going to be able to help you with this issue, you are going to have to attach your model.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save to your hard drive. Then use the Attachments section of a forum post to attach it.

hi @Anonymous you have windows in your work where you cannot divide. make this pass with flat bodies too. greetings mango

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

This file...

Hi John

Thanks. The reason I didn't attach the file is that it is 135MB, which is substantially larger than the 71MB advised and zipping it doesn't work to reduce the size.

I also only have the option to export an archive file (f3z) and not the f3d file.

Here's a link to the f3z file: https://www.dropbox.com/s/10ugrsbtwjj8z16/PI_0069509_C%20Mould%20Design%20v52.f3z?dl=0

Not sure if that'll work, but here goes.

Hi CADWhisperer

Thanks for the reply. 

Here's a link to my f3z file. The file is too big to attach to the post and Fusion only gave me the option to export an archive file.

Hope that helps.

Hi Mango

Thanks for the reply.

I'm not sure I understand your post. The windows you've indicated are closed by surfaces and they sit against the runner bar and under the bottom side of the gates.

However, this is the area I have a concern about. I'm not sure if the surface below the gates is causing a conflict with the cut made by extracting the solids. I was hoping to patch the areas between the gates, casting and the runner bar, but Fusion doesn't allow me to select these line features to make the patch.

I've provided a link to the f3z file if you'd like to examine further.

hi @Anonymous -- I think in the shadow you can see that there are two open windows. I put the mark where it can be clearly seen. Please go through your component with a sectional analysis, as you shouldn't see any contours that have grown together. turn the cutting analysis surface a bit, otherwise the narrow contour of the sewn surfaces cannot be seen. greetings mango

hallo @Anonymous a new analysis shows me that it would be better to remove the radii so that they can later be generated more easily in the trough. the picture shows many holes in the outline. i wanted to try extrusion on an object, but that is not possible without good profiles.

Hi @mango.freund, thanks for that way to check for missing lines - looks very good. I am assuming you projected the patches and surfaces to a sketch to get the lines?

Interestingly the guys that designed this in SW were discussing the number of very small facets that have resulted from the radii on the thin sections of this part and how that's causing problems for them to split the model, too.

I will see if I can replicate and repair the parts on this basis.

Can you Attach the original *.slprt file here for diagnosis?
