I've been looking around and i haven't quite found a way to do this yet without going through a lot of trouble.. I'm trying to curve a plane. To be clear,i'm not trying to do this: What is the fastest way to create a curved plane?

What i'm trying to do, is this: Single inwards curve

What i want to do is put inward curves on all 4 edges, and possibly a curve on 'top' of the plane as well. I managed to get one inwards curve by using the Curve Modifier, but i haven't managed to get multiple curves at once by using this. also, it messes up the rest of the plane when i do that. So, is there a way to do this?

P.S. For anyone who wants to know, i'm trying to make a shadesail for a 3D house project. The last time i did a shadesail, I made it manually and it took AGES so i'm just trying to find a way around this problem. Thanks :)

Note: This is non destructive way to do such thing. You can always use Proportional Editing to directly model this shape.

  1. Add a Plane and Subdivide it as much as you need/want.

1

  1. Add Lattice and Scale it by 2.
  2. Go to Lattice Data tab and set U: 3, V: 3, W: 1.

2

  1. Add Lattice modifier to the Plane and choose Lattice as Object.

3

  1. Go back to Lattice in Edit Mode, select needed vertices and Scale them down and also move center vertex on the Z axis.

Add a Plane and sub divide it to 8 and then 2 subdivide again to get a smooth

Add Empty

With the plane selected Add a Cast Modifier

In the control object select Empty

And with the empty selected pull up or down to get the shape

You could add a Circle. SHIFT + "A" and select "Circle" from the drop down menu.

TAB into Edit Mode and extrude inwards. Press "E" + "S" SHIFT "Z".

enter image description here

Then delete unwanted vertices by selecting them and pressing "X".

EDIT: Another option.

Add a Plane. SHIFT +"A" select Mesh > Plane from the drop down menu.

TAB into Edit Mode. Add some Loop Cuts. CTRL + "R" > Mouse Wheel to increase the number of Loop Cuts.

enter image description here

TAB into Object Mode and press "A" to deselect the plane.

Add a Bezier Circle. SHIFT +"A" select Curve > Circle from the drop down menu.

enter image description here

Select the Plane and add a Curve Modifier. Choose the BezierCircle as the Object in the Curve Modifier Pane.

enter image description here

Select the Bezier Circle and press "S" to adjust the scale.

enter image description here

You can also select the plane and adjust it's scale 0n the "X" axis (in this example.

  • $\begingroup$ I thought of that, but then i would have to add 4 circles, delete all the unwanted parts, and join them together again; then i'd have to reshape the entire thing to fit the curve that i'm trying to get. That would basically take just as long as my original method... I was hoping this could be done with the curve modifier somehow... $\endgroup$ – Tyrel Oct 11 '17 at 13:59
  • $\begingroup$ I'm confused... 4 circles, delete, join? $\endgroup$ – Dontwalk Oct 11 '17 at 14:06
  • $\begingroup$ Ok, i'll try explain... Basically, i need this- db1736767dbd5e7094bb-d61bbc5d0b342a54145a236e2d5d1ebf.ssl.cf4.r… --thats a shadesail. All 4 sides of the square curve inwards. Using the method above, I can only get one side to curve inwards. I've been trying to use multiple curve modifiers on one mesh but so far...nada. If I was able to use 4 or more curve modifiers on one mesh,then there would be no problem. $\endgroup$ – Tyrel Oct 11 '17 at 15:09
