How to Chamfer Text Embossed on Cylinder

[christopher_125]

I’ve run into a roadblock with a design and would like some input on how to approach this. 

I have a logo containing text (.dxf) which I use to emboss onto a cylinder. However, the part will be 3D printed, and is required to be support free, so all overhangs (the embossed text) need to be chamfered 45 degrees to the cylinder surface. On a flat surface, this is pretty straightforward, but since it’s embossed on a cylinder, the faces aren’t planar and can’t be extruded. I’ve tried chamfers, ruled and rounded fillets, lofts between the text and cylinder faces, drafts, sweeps using profiles, pipes using a triangular cross section and surrogate emboss, but all result in errors and fail to create the required chamfer due to the varying face widths of the embossed text faces. 

Does anyone know of a workflow that would work to chamfer text that’s been embossed onto a cylinder?

You probably will  have to return to the old method of creation Text on a wrapped piece of sheet metal.  I have attached a model with text with a 20 degree chamfer to the surface, 45 degree is rather steep for any text font.  If this suits and you need further explanation, besides the timeline, let me know.

Hi! Another workflow to consider is to use Ruled Surface command to create protruded surface at a given angle (relative to the cylinder). It could be a bit tedious, since you will need to do it on a per alphabet basis.

Many thanks!

Hi,

Are you able to provide the logo file for us to play about with?

Cheers
