Adjust Perspective?

How does one adjust the perspective mode in the view cube - and how to reduce the size of facets displayed on circular items.

    Neither of these attributes is adjustable at present in Onshape.
    I have submitted a ticket requesting the latter (faceting control) and I know Mark Biasotti had previously made the same request - no doubt you could ask here to be added to the ticket.

    Perspective should also be adjustable. Right now, the default is way too extreme to be useful.

    @kinsleymark  I agree, I have to zoom out a lot to get decent screenshots from furniture models.
    I like the feature that you can go through things when perspective is on, I was just flying inside my new warehouse aisles looking at pallet racks.
    Especially with 3d mouse, moving inside building is fun (like a game).

    @briancad , Currently these facility is not available and hope that Onshape will provide In near future. I have one work around it may be help in your case.
    1) Turn perspective view on
    2) With the help of view cube you can move view according to your requirement and get respective perspective view.

    To OnS's credit - at least they have it. I remember when I saw SW'95 demo'ed for the first time, it was the first question I asked "where's perspective?" - Perspective did not happen until SW'96 i believe.

    I think I figured out what bugs me about OnShape's Perspective:

    With OnShape, it seems like the closer "the camera" gets to the model, the more intense the perspective gets and it becomes unusable. Like @3dcad mentioned, it works best when you're really zoomed out.

    However, with SolidWorks, zooming into a model is more like zooming into a PICTURE of the model. The model doesn't get warped the closer you get to it. The view is pretty consistent no matter how far you are zoomed in or out.

    I'm attaching two screenshots showing a gradual zooming-in of the same shape in both SolidWorks and OnShape. You can see the difference.

    OnShape's perspective is probably more real-world realistic - but that isn't very helpful if there are no rendering capabilities. For basic modeling, I prefer SolidWorks' mechanism.

    I think I prefer the real world scenario, if I don't want the real look I'll just turn it off.
  • 3dcad3dcad Member, OS Professional, Mentor Posts: 2,441 PRO
    Currently I would prefer SW / GD style where zooming is like picture. But if we get better high resolution output (no screenshots) then I prefer real world style since that gives you control for perspective strength by zooming in/out.

    But to be honest, if you take any small piece from your desk and bring it close to your eye - it doesn't look like Onshape makes it look. Your brain corrects the perspective and choose to zoom in picture style.

    For example 'usb stick' 30x15x6mm doesn't look like this no matter how close to your eye you put it:

    But if you look into empty 4000x4000x2500mm room from the door, it is pretty much like it looks in Onshape:


    So the problem is only with small parts.

    There is also another thing; for printing you need to move model around screen to fit into page then straight-front view can be like this:

    This is purely printing problem, we should be able to choose the printing area. It is good that perspective changes when you drag the model from left to right or so..

    This seems to be a feature I need at the moment. I've seen other examples with a field of view adjustment (in degrees) which allows the user to manipulate the perspective / lens. Sketchup does it well enough.

    Anybody know what the keyboard shortcut TOGGLE is, for perspective view ON/OFF?
  • NeilCookeNeilCooke Moderator, Onshape Employees Posts: 3,112
    @ricky_barnaby - there isn't one. You can vote on an improvement request (if there is one) in the category on the right --->

    I agree with 3dcad above, we have no problem with perspective on large models. The two images below show a Oil Platform Jacket with no change in viewpoint, only perspective on - off. 
    The jacket is 40 meter wide (as seen through it here). 
    It is actuall very difficult sometimes not to use perspective to orient yourself inside the model.

    My original question nearly five years ago, if not made clear then, was asking if the 'perspective angle' could be set or adjusted by the user.  While the extent of 'zoom' seems to influence the perspective displayed, I need to match CAD views having good screen resolution to real world photographs.
    I never continued with Onshape, but wonder if this capability has been added since.
