Question about sculpt mode

[gavriilklimov]

Hello -

While in sculpt mode is there a way to add edges like a regular 3D software ?

For instance, if I have this:

I'd like to add edges in this fashion 

To create a 'diamond' shape.

So that I could pull the vert in the middle creating that specific shape

I can't seem to find any "slice" or "cut" tools to add edges any way I want in Fusion.

Is it possible to do this ?

I think the closest you'll be able to come to this in Fusion is in the Sculpt environment.

To start, click on the "Create Form" command in the Model workspace. This will place you into the Sculpt workspace. Under Create, select Plane:

After the plane is created, select the "Insert Point" command in the Modify menu. Click one of the midpoints on one of the plane edges, then work your way around the perimeter of the plane and click each midpoint. A green line will appear between each sequential point. Click OK to finish the command.

Under Modify, click Edit Form. Select the midpoint of the plane, and drag it upwards. You'll get a rounded shape like below, which is typical of the Sculpt environment.

If you want sharper lines or a more defined shape, there are a couple things you can try. In the first image above, there were options for "Length faces" and "Width faces". You can try increasing the number of faces, which gives you a bit more control over the shape. Or you can try "creasing". Under the Modify menu, select Crease. The next two images demonstrate what will happen if you create around the perimeter of the diamond:

And this demonstrates what happens if you also crease the center lines of the diamond:

Hope this helps.

Word of advice......don't use triangles.....ever.

Look at the screen shots Joe posted see how triangles mess up your geometry and your surface?

Hello -

thanks so much for your reply @joe_wright1 .

It was very helpful.

I have now a further question. How would you go about doing it in a case where for instance the shape is cylindrical (or has a non-flat body)

For instance, look at this beer can and the way its surface is shaped.

How would you go about doing that ? In regular 3D it's pretty straight forward due to the way selection tools and arrays work.

Can the sculpt mode of Fusion achieve the same? If so, would you mind showing me how would you tackle this in an efficient way which wouldn't require to do it on all the single faces one by one ?

Thanks again for the help.

Hello @PhilProcarioJr -

Thanks for your reply.

How would you go about creating a diamond pattern without pulling up the middle vert after you slice a square ?

In regular 3D (i.e. in 3ds Max, Maya) to create that sort of pattern, you would do it on a flat plane, pull them up, apply a 360 bend and to close it up.

Other than that, triangles can be used when needed to create shapes that can't be achieved otherwise.

Let me know -

To be completely honest, this is going to be a pain to do correctly in Fusion but I will make a video showing one way to do it.

Personally if it were me I would model this in Maya, or any polygon modeling app and import the obj and convert it to a T-Spline....

I didn't see the part about you not wanting to do each face...in that case import the geometry from your other 3d app.
