export surfaces in obj format

  • Start date Start date
I find myself having to close this portion of surface:
chiusura_3_v.webphaving only 3 edges how do I create a "attached" face?
 
in the "crea" menu there is the "create line" command, so you can create the line that unites the points, then from the tree the selections, dx key, "allinea" command, you can decide the tangency or perpendicularity to other corners or surfaces.
so you make what you miss.

in the case of lines of the same direction that join in one point (a triangle in short), the blend command, accepts in one of the directions, a single line.
in the "options" box of the blend, there is the "fluid curve" collector that serves to determine the trend of a surface, when you have only 2 lines for one direction.
 
in good substance I should close this surface to solve the problem:
pezzo.webpJust that the operation is really long... .
 
but the tangence is missing on all the edges?, or is it respected?, because so in yellow I can not understand.
 
missing the face, but the operation takes too long, I think for now I have to abandon and go through other sw.... The more I go, the more complicated... .
 
the surface you can do it quietly with the contour, then "modification" menu, "cut" command and select the surfaces to create the opening in the middle
 
creo also exports assemblies with models without volume in .obj format
in the .obj export menu select first #all (for components with volume),
then #complete
Select surface of the component without volume and not the component itself.

Hi.
hinges
 
perfect, then I'll show you the steps I do like this, if you like, explain to me what I'm wrong:
1.click on file -> save by name
2.imposed as obj format
3.I choose a path (without spaces)
3.I choose a name
1532012557009.webp4.premo the ok button
5.select everything, then inside the model tree select the coordinate system
6.I choose the definition level by setting rope height and angle control (for convenience now I leave those proposals)
1532012862649.webp7.choose add.. .
8.I try to select the surfaces I want to include in export (the only thing I can select is the entire geometry)
9. Click on apply to display mesh
selezione.webpAt this point I should see the blue geometry with the coligoni that I create will export, but I keep not seeing anything.
What's the mistake?
Thank you again!

the second direction would be better, because if there is a tangency problem, you report it when you bring the surface to the domain.

probably there is still a mistake on the edges of other surfaces (which are the errors that have ruined the original surface you have erased (but you couldn't do otherwise)

other command I command you, is geometry control, where it gives you all the errors detected in the tangence.
errors on the nodes and tangences however verified (the ones in dark violet) are negligible (the solid does the same), instead of unchecked tangences and holes, they must be settled, but this command also finds the microscopic ones.
Maybe put an image of the diagnosis with the errors detected.

hi 320i s I think I have identified the reason why I can't take the second direction:selezione.webpif you make us case the lower curve does not have edges in common with the side.o_o

to select the model without volume select model, right click
and take the entire surface.
(x.prt is a volumeless part)

in this case, you have 2 possibilities:
1-selections the 2 parts of the line and command at the top "unisci" (you can select multiple segments, but if they are segments of other adjacent surfaces, you cannot join, and in some cases, the union can change the radiation of segments, then better evaluate)
2-with the shift key select the segments for that particular curve, for that particular direction, so as to "close" the contour; but then more surfaces will be created from the system; in the m, where you transpose the new surfaces into the domain, you will notice that a segment, does not close the tangence, because that edge, has 2 surfaces to be combined; then view the nodes, select the entire segment, select the command "divid", approach the intermediate node you see on the curve and click on the node; If everything goes well, you split the segment to the right point and the tangences will be respected.

Okay, I know I'm breaking up but be patient, let's take the steps you've indicated to me:

solution 1:

part of the following condition:
1.webpholding down the ctrl key select the two curves of which I want to join the tops at the end, then select merge curves:
2.webpas you had predicted I did not get results
3.webpI have no idea what to do.

Thank you.

Now you see a second export group.

perfect works! Thank you so much you saved my life!!!!(y)(y)(y)(y)
 
Ragazi I thank you both are great and you have had what you call the "young fatherhood" with me! :):) Thank you 100000000!
