GSD STUDY

(OP)
Hi,

How could I convert all the surfaces included in the Geometrical Set.1 into a solid?
I run "Join" in GSD:




Then unchecking the "Check Connexity box:




and then "Close Surface" in Part Design:



But I got this message:


Can you help me to find the right method to get a solid body?

Thanks!

RE: GSD STUDY

1 delete the join you did
2 create new join with default parameters Check Connexity and Check Manifold = true
3 select last surface from your geoset
4 from the Create Join GUI, select your surface and rightclick Distance propagation
this will help avoiding none connexe element
5 do a preview see the holes in green (1 big and few small)
6 change merging parameter to 0.01mm
7 do preview again and see that small holes are "gone"
8 smile you are progressing and validate the join
9 select all surface in no show (all but first one and join)
10 create a geometrical set (by default all selected element will go inside the new geoset), this will make shorter tree to work with when you shrink the new geoset
11 define old geoset as current
12 create boundary curve of join
13 project the boundary on the first surface (354)
14 disassemble the projection
15 delete the few lines/curve in the corner
16 extrapolate the line too short up to the other line, working on surface.354 as support
17 create a new join
18 select the extrapolate
19 in the GUI, do the rightclick distance propagation again
20 do preview to make sure the curve is closed
21 split surface.354 with join curve, keep the inside :)
22 create new join with first join and last one
23 do the preview / merging distance again
24 extract boundary of last hole
25 fill the boundary
26 make last join with fill and previous one
27 adjust merging distance with preview
28 make solid from last closed surface
29 go get a drink, you deserve it (I know I do...)

Itsmyjob,

Thanks a lot for your fast reply.
Can you add the CATPart that I suppose you've done?
I'd like to analyze it and learn your procedure on a logical succession.
Thanks!

P.S. I use Catia Version 5-6 Release 2016

RE: GSD STUDY

sorry 3DX18X, export will not help you as all will be isolated.
just follow the steps it should work
if not, post your progress and i will look at it

Itsmyjob,
I got up to here:

1 I deleted the join I did
2 I created a new join with default parameters Check Connexity and Check Manifold checked
3 I selected last surface from the Geometrical Set.1 (Surface 353)

From this point, I wasn't able to advance:

4 "From the Create Join GUI, select your surface and right-click Distance propagation this will help avoiding none connexe element"

Q What did you mean by "Create Join GUI"? What "GUI" stands for? Sorry, I am not a proficient GSD terms user......

RE: GSD STUDY

if you set merging parameter to 0.1 you will get rid of all the small holes... you will only need to trim the first surface (.354) with the boundary of that join.
then add the two surfs (Join and Trim) into a new join (having same 0.1 merging tolerance).
and make solid by the closed surface command

LWolf

Thanks LWolf,

I'll try that right now.

LWolf,

It works, I got the solid!
It looks like the surface 354 was larger than the area where it should have fit and creating another surface( I did that, instead of trimming surface 354) fixed this
issue.
Was this the only issue that caused the initial failure?

RE: GSD STUDY

GUI mean Graphic User Interface its the windows that opens when you start the Join function.
in that window you will find the surface you select (in 3D), then you right click on the text inside the GUI to get propagation mode.

How did you find out about that unfit surface (354)?
Checking each of all 354 surfaces take a lot of time!

RE: GSD STUDY

i picked a random surface and did the join propagation, the only one left was surface.354
