Free transform a shape

clea

I'm trying to create a fire pit shape for a landscape plan. I cant get the retaining walls edges to slope down.. I know it must be simple.. can someone please show me how to do it?

Curvishear, push pull up, erase extra, then curviloft to skin the top. I adjusted the top faces a little to smooth the profile at the peak. To adjust just a few edges and faces downward, you have to draw edges to break the curves that curvishear created so the edges move independantly of the curve.

To my mind the best shape would gradually round over to the other side and I am not sure how to do this simply. I suppose it is some exponential function whereas curvishear is a straight slope. But Dave's has a cool Gothic feel about it.

I like that one Frenchy. I couldn't open the file either. No matter.

As I can't reload your file i have no dimension
(Save as V6 for a more large audience
First forms are trivial then
I will use True Bend By Thomthom who bends a single group / Component

TBoy

Or FredoScale-Box Tapering.

Front rectangles will be deformed and have to be corrected to keep the right angle

Heights are good...general bottom is a flat face but...
There is just a little default!

The facett ABCD is not a "plane" ! A quasi plane ! (like Curvy Shear, Shape Blender, Flowify)

So depend of what do you want exactly...image or build construction drawings!

So maybe use Upright Extruder Edit: In fact not better!

Following on from pbacot's post and pilou's suggestion to use an upright extruder. This method will give a uniform curve to the top edge.

Draw a circle centered on the firepit base.

Rotate the circle down to desired position and intersect with the firepit.

Delete the circle and intersection lines apart from one curved edge. Trace an end profile (make it longer at the base to allow for triming)

Extrude the profile (I used Eneroth's Upright Extruder). Trim the excess extrusion at the firepit base.

If you don't have a version with Boolean you can use the French free"Bouffe tout" by BLB
(free register needing)
Volume(s) must be a unic volume Solide Component
Surface(s) must be a unic group (not a group of groups)

Else you have this cool one "Coupe" by BLB Bois! Was Free but now inside this a complet pack for wood makers! (39€ /year for 36 marvelous wood's plugins for Pro wood makers works also for Make version
