    If you can use the Wetransfer web link I gave to you. I will do it for you, as it looks like a simple object. No need to register.

    Or upload the image here.

    I'm 'Pending approval ' again.

    Here it is https://we.tl/t-3rHJ0tzBPa

    Before you go to a lot of trouble, this is only an example. I'm really more interested in how you do it than actually getting it done if that makes sense.

    Thank you again for your help

    That did not work. The following files were not found 'wider logo.rsdoc' when I opened 'wrapped surface'

    Either upload the original file or 'Pull' the surface logo into a solid.

    I will explain more.

    I'm sorry, how about this https://we.tl/t-NtSALzVFQq

    I just saw that I posted this same question two years ago. https://designspark.zendesk.com/hc/en-us/requests/6531

    That link does not work for me.

    I can't find my old link. However this can be done in Sketchup with the 'Chris Fullmer: Shape Bender' plug in. DSM can read and write .SKP files.

    Thanks I've been using an old version of sketchup (version 8) to create text that I can import into my drawings.  I'll check out the plug in.  

    Thank you again for your help

    A native way to approximate this.

    I have this text I want to wrap around a cylinder:

    I take a copy of the cylinder's surface:

    Split that surface into 4 quadrants

    and unwrap them parallel to the text:

    This is done by rotating the two quadrants on the right by -45 degs:

    And the the outer of those two by -90 degs:

    Repeat for the other two quadrants in the opposite direction:

    And project the text onto them:

    (Be warned: this takes a while because DSM insists on projecting everything onto everything else BEFORE it will let you tell it where you actually want it projected!)

    Now rewrap the quadrants back to a cylinder, which is just the reverse of the unwrapping (with the caveat that you have to ensure that you select everything that needs to be moved each time):

    But ONLY that which needs to be moved:

    (thanks goodnees for UNDO :)

    Now you can delete the four quadrant surfaces

    And (carefully) the remaining unwanted bits:

    Then I select all the surfaces and Pull them in both directions 2mm. This alows me to either emboss 1mm by Combinung them with the cylinder, or etch by 1mm by interecting them with it.

    Of course, the results of the projection onto the quadrants isnt perfect, and for some the distortions would be visible. This can be minimised further by using more splits, 6, 8 or 12, if the extra work is worth it.

    Ideally, this would be automated.

    A similar process can be used on compound curves, though if the stuff to be imprinted takes up a large proportion of the second dimension of curvature, the distortion would require more complex unfolding.

    Here I split and unfolded/refolded the sphere itself:

    @me here, thank you so much for doing all of that work to demonstrate what you're talking about. The concept will work for what I want to do.  Fortunately I don't need to do a lot of it. Thanks again.  And yes, having the wrap feature would be really really nice

    No worries Perry,

    I'm currently forcing myself to spend a week using v5 in exclusion to any other CAD, to see if I can recover some of the joy I remember from using v2, rather than the frustration and revulsion I got when I first started using it a few days ago. Working out how to do something reasonably difficult makes it easier to concentrate on the goal, rather than becoming frustrated by its differences and limitations.

    Having done the sphere above, I went on to see if I could wrap text around an arch, and I succeeded.

    Starting with the vertical text and horizontal arch (both in green), I segmented the red vertical surface using the yellow surfaces, straightened it out, project the text onto it and wrapped it back around. Then I projected it onto the orange conical surface, and then from there onto the horizontal arch.:

    The result is pretty good:

    All.

    Here's yet another way....

    By imprinting the text onto a flat plane, individual letters faces can be made and moved individually.

    By pulling the face upto the curved surface then, cut / pasting the mapped surface and moving it into the owning component, then pulling it to a solid auto joins it.

    Select the owning component ( all letters attached) again,  rotate it around a set amount. ( i used a point within the sphere for the move tool to ankor to.)

    THIS PROBABLY WILL NOT WORK WELL FOR THE OP'S PROBLEM.
