    Following the numbers in the image.

    2. Draw two curves that are tangent to the two solids.

    2 / 3. Pull the two edge loops on the solids, use the 'Sweep' option to pick the two curves drawn in '2' to act as the defined path.

    3 / 4. You will notice that two surfaces are created. Delete the one that is useless.

    5. Hide the two solids. Select the edge loops at each end of the new surface.

    6 Use the 'Fill' tool. A solid should be created.

    7. Use the 'Shell' tool on each end of the solid with the correct thickness.

    8. Unhide original solids. Use 'Combine' join to unite the three solids into one.

    The middle section will still be associated with the Shell tool.

    Select the model Copy - Delete - Paste.

    This will give you a solid, without the shell association.

     

    If the hole and the slot are different diameters, then do the same as above numbers 1 to 6 . Using the inner edge loops of each solid.  'Combine' Cut the inside solid from the outside. Join together as 8

    A lot easier in V1. Although it can be done in V2.

    The 'Blend' tool in DSM V1 is omitted from DSM V2.

    Thanks - I'll give this a try this evening

    Can't quite get this to work properly

    Circular tube diams are > 'Oval' tube diams

    Created a plane - so could define lines between 2 solids

    Selected Pull

    Picked the Loops for the inner bores of each solid

    selected sweep

    Picked both lines

    Clicked Full Pull to generate new surface joining both solids

    Doesn't always produce 2 surfaces (no big deal)

    Surface hasn't followed both 'sweep lines'  -- one side has followed some curve ??

    Have tried with sweep lines at different points - same effect

    Any thoughts on how to solve this ??

    Many thanks

    I only use V1 of DSM, so even if you sent me the file I could not read it.

    Can you give me the sizes and shapes of the two 'Surfaces' you are trying to join, as well as the distance and position of each. A screen shot with dimensions would be good.

    Make sure with the curves you draw that the start and ends are tangent to the solids.

    Sometimes it makes a difference if you select the edgeloops and paths differently.

    It is all to do with the start position and direction of the Pull, indicated by the '0' and 'X'

    I just used 2 straight lines for the sweep path

    Inner bore shown below


    Thanks for your help

    Circular tube is 4mm Inner diam, 8mm outer diam

    'Oval' tube is 1mm Inner diam, 3mm outer diam

         2 * 1mm circles 10mm centres apart

           tangent line top & bottom

             trim away internal arcs to produce Inner 'Oval'

    Repeat above with 2 * 3mm circles

    Now you have the basic surface I'm trying to blend to from my Circular tube

    ??Do you get a clean solid - can't get the shell step to produce correct result

    Solid is NOT correct

    As you can see top has followed a straight line - bottom has not

    I'll keep trying

    This still works. Select the circle loopedge first. If it does not work the first time try pulling from the yellow arrow.

    You need two sets of lines.

    However when I Pulled the outer edges It only did one side. So I filled it Duplicated it by Pulling and rotating then I Combined the two together. Then Combined - Cut the inside from the outside.

    Here is a link to the file. It is V1 but V2 will open it.
