Hi,
I’m looking for a solution in SolidWorks to extend the internal open loop to 5 mm and patch in G1 or better in G2.
Have you a solution to indicate to me how obtain it ?
Hi,

Did you tried using "Extend Surface" option with End Condition as Distance (5mm) and Extension Type as Same surface.
Before to post I tried all type of modification surface.
Another problem is to patch the open loop with the fill surface.
I just tried extend surface on few edges with 5mm distance and it worked well.
Gupta,
you have tried on few edges.
If you are dedicating time, please doesn't test on some edges, go head.
I'm looking for a solution, not if some command are working.
SolidWorks can do it with few commands or I need to send to my friend with other CAD ?
Hi Alessandro,
Break it up into 3 or 4 fill surfaces and then you can do a G1 patch. Fill is a magical tool but it is not that magical To do the complete boundary with one Fill is not possible because of the ambiguity that it presents because of the wide variation of tangency change.

Thanks for the tip Mark
Hi Mark,
thank you for the suggestions.
Before to fill, I need extend for 5 mm for mold blades, then fill.
Sincerely the fill surface create bad surface and I can't send to the CAM.
I asked to my friend that have other CAD and I attach the result.
Problems are two :
1) Extend open loop to 5 mm (white surface), then...
2) Patch minimal in G1 (green surface)
Which tools do you suggest me to extend and find the better position for extra curve ?
Hi,
In my working practice, I use extend surface/ ruled surface/ loft/boundry surface or combination of these to extend surfaces.
make sure during using Loft and boundry change end condition as per need " tangency to face/ curvature to face".
Also during filled surface use points in constraint curve to get desired shape.
see the attached model. might this will help.

Hi Kumar,
very good work.
Two questions :
1) How have you understand / decided to cut the surface in that place ?
2) How to find and position all those points ? I don't think you have positioned random.
Thank you again,
Alessandro
Hi Alessandro,
thanks for your comments..
My inputs against your question.
1) How have you understand / decided to cut the surface in that place ?
I found this during creating 5mm extension of surface and I think its just a experience and hit & trail method.
2) How to find and position all those points ? I don't think you have positioned random.
Again I say that I put these points randamoly as per your referenced pic.. One thing which I noticed that points must be placed at such postion which help to surfaces to
flow as per need.

Hi Kumar,
sorry for the delay.
Then without picture how have you obtained this good surface ?
Your opinionion.
