Create space between objects?

    Select one solid and use the 'Move' tool with the 'Ruler' option. Place the 'Anchor' at the place you want to move, use the 'Ruler' option to input the 'Dimension' from it or from another solid, face or edge.

    You may need to add a 'Tolerance' to one of the solids as part of the design, if you want them to fit together.

    If you have two mating parts where the mating surfaces are the same nominal dimension

    And you want a clearance between them, then you have 3 options:

    1. Make one smaller.
    2. Make one bigger.
    3. Adjust both by half the required gap.

    That seems like a very obvious answer; which makes me think that your question is more involved?

    Thank you for your help. My objects has a quite complicated shape and I had made the gap to small which made the print to fail, then I hoped for a function for easily increasing the gap. I realize now that it is not that easy to have such a function to work. After struggling a bit I found out that the easiest way was to select all the relevant faces and use the move tool to increase the gap.

    But still, any assistance from the software to find any areas where to objects are closer to each other than a set limit would be useful.

    Hi Charles.

    Yes, you said...

    'any assistance from the software to find any areas where to objects are closer to each other than a set limit would be useful'

    and i fully agree.

    In DSM, touching faces and shared volumes (intererence) are shown in red  under Show >Body Interference.

    Collections parts always have touching faces - so for DSM i'd like addition control to show/hide Touching Faces.

    For higher level analysis of specific clearances - the upgrade path is Ansys Spaceclaim. DSM is highly capable but it's just a small subset of Ansys Spaceclaim.

    Online searching I found this... ( however, there's no harm asking for this to be included in DSM - feature request . Edit, i've just done this..)

    I don't know of anything that does exactly what you asked for, but if you have two relatively complex solids, eg:

    Then if you select both and click the measure tool, it will tell you the closest distance between them:

    It would mean working through all the pairings of solids in your model, but with a little planning it shouldn't be too tedious, unless you have many solids.

    Hi Charles.

     

    Further to Buk's very useful answer, in consideration of complex interfacing bodies, I'd like to throw in that complete selected bodies or faces (individual or collections) can be shown as 'Inverse Face Visability' (rmb >face> ...) or hidden - latter case offers selection / working from inside the bodies if desirable.

    It's also possible to select bodies or faces , curves, points not actually displayed, but instead directly in the structure browser for distances min and min in ZYX directions as well.

    Hope this may be useful.

    Thanks a lot. Both your answers will be very helpful! I have only used DSM for a couple of weeks and there are a lot to learn :-)

    Hi Charles. Yes, sorry about the verbose responses.

    To explain, i use the questions as purposeful motivation to learn by exploration.

    So, another extremly useful command instead of the move tool, is to offset all selected faces by a distance in one go using the 'Pull' tool.

     

    and with careful selection, fairly powerfull results can be obtained for shrinking / expanding all selected faces in one go by a set amount i.e -0.1mm.

    Take a look at scaling to - but 'PULL' probably IS THE ANSWER !

    A combination of selected pull by an amount, plus additional move faces looks quite promising for your original problem..

    Note, cylinder height and diameter sizes not selected, thus unchanged. I could have also additionally selected the cylinder dia ( now 11 faces) to shrink in one go ( but i forgot !)

     

    NEVER have i needed this before... to shrink / grow parts by a direct value input, select the part by triple clicking it or boxing selecting it in the design window only and entering a negative ( removing material all over), or positive value (adding material all over), negative value removes material (hole dia increases ) positive value adds material (hole dia decreases )

    Pulling OMNI-DIRECTIONAL multiple faces ( or all of a part ), by not selecting a direction and just entering a + or - value, works providing no faces are consumed in the process.

    In situations of 3D printing, parts may need additional clearance to function.
