Hello Ultimaker Forum, I am trying to print models designed by a collaborator who is working with SolidWorks. The model has multiple parts. The parts have been exported from SolidWorks as.stl files and sent to me as email attachments.
In this section you will find the solved C++ programs on various basic topics of C++ like – cout, cin, Scope Resolution Operator SRO), inline functions, default arguments, function overloading, function calling with different types of arguments passing etc. List of C++ Basic Input/Output Programs. C++ program to print “Hello World”. [SOLVED] Resolution / Mouse problem I have some problem with the mouse and the resolution: when put in fullscren, the mouse jumps and the cursor is almost never visible, making impossible to select anything.
I am using Cura v. 15.04 create gcodes from the.stl files. The imported.stl files appear to be fine when viewed in Cura, but when I print, approximately 1/2 of the parts are missing surfaces. Has anyone had this experience, and if so, is there a work-around? Many thanks in advance.

Hi mastory, Thanks so much for the feedback. I'm attaching a screen shot and a photo. The screenshot shows the model as it appears upon importing the stl into Cura. The photo is the actual print.
Surfaces seem to be missing; only the fill is present. I'm afraid I don't anything about SW. I have published the dilemma to a SolidWorks forum, but so far haven't solved the problem. I think my collaborator may be creating the problem prints as inner and outer surfaces, which is subsequently combined, but I don't quote me on that. As said, some prints come out fine. A tech at a local 3d printer business suggested trying a Cura plug-in for SW.
We haven't tried that option. Any thoughts would be much appreciated. Having used SW for the past 4 1/2 years I have never once had a problem with it generating models for 3D printing - Lol that is why I keep telling myself it was worth the five grand! This could be an optical illusion but your printed part sure looks thicker than the Cura display. I wonder if the model walls are too thin.
Best to check with your SW guy - ideally you want them to be at least twice the width of you nozzle. Set Cura to x-ray view - any red colouring displayed will indicate errors in the mesh, which would surprise me coming from SW. I have no idea if this view would highlight thin walls but it is worth checking. What is the diameter of the circle approx.? Also can you look in layer view and see if the walls, presumably two of them,look OK. For whatever reason the wall thicknesses of this model are too thin for a 0.4mm nozzle to print. You can see this if you switch from the solid view to the layers view.
If I switch to a 0.25mm nozzle in Cura 15.04 I can then see that all of the walls are being printed. The problem lies not with Cura, or the printer, but the original design. Either the wall thicknesses were not made thick enough in the original design, or the way the part has been modelled is as a collection of surfaces rather than a solid model, and some of those surfaces are not connected to produce a solid model. I looked at this in Meshmixer and there were a couple of minor defects that it has repaired, but in Cura the surfaces will only print with a 0.25mm nozzle setting. So I suspect this is a problem with the wall thickness of the model.
would their definition then usually occur outside of the class scope? Not necessarily. Operators can be non-friend as well if access to private members is not necessary. They can be defined outside the class declaration if they seem too long to remain in the declaration. Often people use the friend keyword just so that the implementation can be put in the declaration (even if private member access is not needed), when the function is very small it is sometimes nicer to have it in the declaration.

But this is all just a matter of taste (however, when it comes to class templates, it is usually more natural to have them in the class declaration). The main idea here is that free-functions should be preferred to member functions for essentially all operators that allow them. This is because of overload resolution, function hiding, and other considerations. Just get in the habit of overloading operators as free-functions (friend or not, in-declaration or not).
