Extrude from curved surface of cylinder
I want to extrude some basic shapes from the outer curved surface of a cylinder.
How can I do that.
I will also like to write some extruded text on the outer curved surface of the cylinder.
Any help is welcomed.

Re: Extrude from curved surface of cylinder
Is the attached file/design too basic for you?
I am a newbie...

Re: Extrude from curved surface of cylinder
Thanks, BUT I was looking for something different.
The extruded surface shall also have a cuved face like cylinder.
Can any one please help

Re: Extrude from curved surface of cylinder
Greetings Johannesov, you've added some unnecessary things in to your model.
Delete Pad002
Delete Fusion (select Yes in the Object Dependencies pop-up window)
Delete Pad001
Delete Sketch001
Now you only have Sketch and Pad (which make up the cylinder) and Shapestring (the text) remaining.
Change to the Part (not Part Design) Workbench
Select Shapestring
Select the Extrude tool:
In the Direction area of the Extrude window change Y to 1, and change Z to 0.
Use 10 for length (units are mm)
Click the Apply button to see the result
Click the OK button to exit the Extrude command.
Now join the extruded text to the cylinder:
While still in the Part WB,
Select the Boolean tool:
On one pane select Extrude, in the other pane select Pad, make sure the Union radio button is selected, click Apply, then click Close.
If you like you can make another concave Pad on the outside of the cylinder and subtract Pad001 from Fusion with the Boolean tool again. (Fusion in the left pane, Pad001 in the right pane)
The file is too big to upload to the forum; you can download it here.

See my previous reply, the model looks like this: Just curious, are you and Johannesov the same person?tiwariaditya13 wrote:The extruded surface shall also have a cuved face like cylinder.
Re: Extrude from curved surface of cylinder
Still the direction is constant. Currently it is not possible to extract along the normal of cylinder face. This would mean to apply a non-linear transformation to every Pole of the BSplines. (All geometry needs to be converted, therefore)tiwariaditya13 wrote:The extruded surface shall also have a cuved face like cylinder.
Would be a nice feature request

As you will see from the links in the last post from Bejant, a current work around to approximate what shoogen is saying, is to model and place each letter independently.

In layman's terms, this is called wrapping 2D geometry on a surface.

I don't mind, I'll do it tomorrow (Tuesday).normandc wrote:Well? Who's doing it?
