Curves

pilou

it moves the bottom of the black curve

Group the part that you want not go away! So all the left black lines!

Oh how simple! I did not think about that.

And please one more problem is joining lines. I created two curves. First one curve, looked like rectangle shape made with line - but it is was curve. Then I drawed curve on right side. Then I exploded the first curve and deleted right side, so now, I have three parts. Imagine is like a base for building. I need to connect the lines (the second is still a curve). Is it possible to join the ends with BZ_toolbar? I know there are two icons in the bottom right corner, but this joins only if I edit some curve. Not two curves or one curve + one edge.

And I know there is line which I could use, but maybe there is also some tool which can make it more simple, if you select two objects... Or faces? ....

Joining faces was big headache for me, when I tried to join two objects (with faces) together. It was a pylon made from two halves of various faces, created in difficult object to join. So maybe there is some plugin, who could join two faces, which are close to themselves? There is the problem that the faces have some space between, and different angle, so looking for shapes to join them manually is hard.

Sketchup don't know "Weld" any curves in the space

So you must use a plugin of welding curves Recurve

If you yant draw some faces or curves on the same plan

Just draw a big rectangle : right clik/group it and draw anything you want : they will be "plane"

I dont understnad it too much. I drawn it on a face. I must delete the face because I don't see the line when I zoom. But when I delete the face, I cannot zoom out or zoom in. So I must undo. When the face is back, I can zoom out (or change view to top down) and I can select the edges which are exploded from the first curve. But as I click twice on the top edge, so I see it is connected to the right curve. The left edge and bottom edge are connected together. So there are 2 + 2 connected entities but not connected together as 4 elements in one entity...

Yes, I drawn the rectangle, but did not group it, but for next time I will do...

PS: Ah, now I can zoom and see the lines ... they are not joined. That is because when I drawn the 2nd curve, I ended too far of the edge of 1st curve. Sometimes the curve is visible and sometimes not... You're right, I must to group the rectangle.

Wow, that's great plug-in. It even has menus Select only, which I needed too. And I repaired one edge. The upper left corner is OK, it connected, but the bottom right, did not. Maybe the space is too big?

I intersected two spheres

and I wanted to delete the face in the created circle. But it is not possible to delete the face. When I select, so it is whole sphere face selected. Why?

pilou

If your circle is well drawn on the sphere
with what have drawn this circle ?

Select the Sphere, select the circle: right click / Intersection Selected
Now you can select inside the circle and erase what you want

PS You can post the SKP file (save as V6) in the forum
Upload attachment
it's better than an image!

I did the circle with sphere, the little one. I saw a video tutorial but am confused. She speaks very fast and the demonstration is short.

Thx for the V6

Seems you have successed to kill the intersection's faces

Again when you speak about a video give the adress of the link

For draw on curvated surface there is a cool plug Tools on surface by Fredo 6

So with it you can draw a circle directly on a sphere

Gaieus

Your spheres are groups. When you do any intersection, the intersection lines are always created in the context you are in. In your model, they are outside of the groups therefore they do not interact with their geometry. This means that if you want to get the edges to separate the surfaces (so that you can delete them and make holes), you will need to edit the group, select its geometry and do the intersection that way (with the model).

Alternatively, you can explode the big sphere, select its surface and one or more of the smaller sphere group and intersect only selected.

rumcajs

Yet one thing I am interested how to make the sphere looking more smooth, more rounded. I have some tools like BZ toolbar or blend but this one does not seem to do the job. I can add more details with sandbox but this will not make it look like real sphere.

No me. I have done some action with LSS tools. As I remember that was Follow edges... There was not this kind of sphere in original modul. The original sphere was from 3D Warehouse: Geodesic sphere 02.

I tried to destroy the faces again, but did not succeed to get same result as before. The sphere looked more bizarre on previous try. The image from now:

You can see the 3D join component was the ovalish 3D object and face was a triangle just by purple dot.

You can draw your own sphere with the Follow me tool
from diffrent behaviour
here one
incease your number of segments / circle or arc circle following that you want
maybe max is 100

Click the circle call the Followme tool then click the surface

rumcajs

This is my result

pilou

Try with this one
Don't hesitate to make some try, Arc surface perpendicular, no perpendicular, rotate it, surface out the circle etc...
It's a funny world!

Very nice sphere. How to complete? I never succeed to close it with Follow me. I remember there was some truck in tutorial, but that one never worked for me.

Edit:
Now I succeed to close it. But if I would have bigger object, how to follow whole the path? I know there is some trick like double click or triple click.

When I will add a texture to the sphere, how can I resize size of the texture. I know how to do it with one face, but with more faces, it looks like imposible.

There is a hole in top and a stair. I had these problems. When I wanted to draw a circle inside circle:

I could not find the center point
I had to start upward so when I wanted to move it back, I could not to find centerpoint again
I had problem to draw the circle on different axis even that I hold arrow right or left.

FOr find the center of an arc circle or a circle use this plug by Chris Fullmer
Just 2 segments following are sufficient

Else you can just draw a line on the top, a mine on the bottom (so diameter)
then draw a line from middle of the 2 diameters)

rumcajs

Well, nice plug-ins you recommend to me. Nice tricks. I have seen one more plugin in the video here:
http://forums.sketchucation.com/viewtopic.php?t=18963
he bended a "pipe". Do you know what plugin it is? It also looks very cool.
