I have a problem with Inventor 2016 pro version student license. When I draw a 3D sketch, and I want to come and catch a sketch of another plan, he can't do it... no matter the type of milk. The same goes for the points. It's as if they didn't exist.
Another example. Cylindrical part with a shoulder, on which I want to create a rib: Impossible to catch the surfaces in sketch.
Another example: small extrusion to draw a cube. Once I have my cube, I want to add a growth on one of the faces. I select my face, I start to trace, but I want to take myself back to the corner of the already existing room. But impossible, it's as if the cube didn't exist.
The machine runs very well (12GB of ram, patatit patata) and I do it without problems on my other (laptop) computer equipped with the same software.
What are your opinions on my problem? Thank you in advance.
Do a first test on a volume (cube for example) with a 2d sketch on the axis of the volume and have the cut edges projected (your cut edges should appear in another color)
Second test: in Application Options, Sketch tab: check the 2 boxes Automatically project edge .... and the edges ...; In the Part tab, check Enable 3D handles. Repeat the sketch test through the cube, then on a face.
If that doesn't work, test by selecting project geometry and select your edges (or points) to project
test also by projecting one of the lines of your basic sketch...
(in 3D selected project in 3D sketch)
Last solution I see for the moment: repairing Inventor with the installation software.
