• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Joining (Welding) points together

Sorry if this has been addresssed before. I've been unable to find any information on joining/welding points together.

Example:
1. Add "Sphere"
2. Delete the points on the top half of the sphere. We now have a hollow hemisphere.
3. Add "Disk" (Of correct dimensions to form a cap for our hollow hemisphere).
4. Align the points of the disk and our hollow hemisphere.
5. "Joint" the two parts.
6. Now we have a flat topped hemisphere.

Is there some way to join/weld the points on the edge and eliminate some of the points?
 
In your project properties (File -> Project Properties), check what your "scale factor for 'Snap to Scale' operations" is. I like to se mine to .001 (default is .01 or such)

Then do a snap to scale operation (Part->Snap to scale) on the joined part.

The snap to scale, "snaps" the points on the part to an invisible grid, that now you have set to .001, etc. two co-located points are drawn to the same point in the grid and automatically joined.


Note that you can also go around and select each pair of co-located vertices and (J)oining them together.
 
Even simpler:

Example:
1. Add "Sphere"
2. Delete the points on the top half of the sphere. We now have a hollow hemisphere.
3. Select one vertex on the open edge of the hemisphere.
4. Add a "Cap Holes" modifier to the stack.

Done!

And, pray tell, where is the "CAP HOLES" modifier in FSDS?


(of course, the equivalent FSDS way is to mouse select (F11 plus click-drag) the vertices across the hole and then CTRL-P to (Polygon->Create Polygon from Selected Points) create the covering polygon.
 
An other way :

- delete useless points,
- select the points around the polygon to create (the top ones on your project),
- Select Menu Polygon, click Make Poly from Select Points.
- if necessary flip the new polygon to face where you want.
 
Thanks

FelixFSDS and jpfil:
Both of your ideas worked perfect. Thanks very much for your help. It's nice of you to help a "Green Newbie" even when the question may seem to be a dumb question. Hopefully if I'm lucky I'll be able to pass this along to some other Newbie.
