    Float Helicoil Options

    Maybe a barrel nut, instead of a helicoil. e.g. NAS577

    NX Motion Center of mass

    I suggest placing Markers at the center of mass of each body. You can then plot the coordinates of the Markers. If the bodies move relative to each other and you want the combined center, then I would export the individual Marker coordinate data to spreadsheet and calculate the combined center...

    old aircraft wire

    potential clue (from QQ-W-412): Checking 465a, the properties listed for Class B align perfectly with the properties listed for QQ-W-429 in my previous post above (209-308ksi). This leads me to believe 429 was intended to superseded 465a Class B, but was shortly obsoleted. The cancellation...

    old aircraft wire

    Maybe this will be helpful (attach), it lists the tensile strength. found here: https://www.google.com/books/edition/Drafting_Room_Manual/V_Y1AQAAIAAJ?hl=en&gbpv=0 edit: I see now that this was already posted above...

    NX1961 sketch direction

    Can you use "Reattach sketch" ?

    Generate curve from path of a point on mechanism

    Is it possible to create a curve from the path of a specified point on a link within motion application? A simple example would be to display the coupler curve of a four-bar linkage: https://www.youtube.com/watch?v=rjxnoQz4xDs I've tried two ways to at least get a visual display after running...

    Motion Simulation Error: cannot open any saved simulations

    I did build the components of the assembly from parasolids so that may be a clue. In this assembly model I have about 10 simulations, each using the same mechanism assembly but set up in different positions for different motions and outputs. Most but not all result in this error when I attempt...

    Motion Simulation Error: cannot open any saved simulations

    Here is a what seems to be the relevant portion of the logfile, for what it's worth:

    Motion Simulation Error: cannot open any saved simulations

    I have a large assembly motion model, which has multiple saved simulations. Suddenly, when I enter the Motion application, and double click on a simulation to enter, I get the following error: "Error occurred during display of part Modeler error: object is not of type expected" Also attached...

    Sketch Line Colors -- colors not showing sometimes when out of sketch

    I've noticed that if I color the lines within a sketch, that when I exit the sketch, sometimes the colors are still showing and other times not (all just gray). What determines if the colors still show or not?

    Tips on kinematic synthesis in 3D using sketch/constraints or other tools?

    This is a somewhat non-specific question, I'm looking for discussion on different methods for doing kinematic layouts (linkage design) in 3D, since generally everyone will develop their own unique variation of techniques. If you are experienced with kinematics and specifically using sketch...

    Motion simulation not animating in multiple viewports

    Using NX11. I'm attempting to set up a simulation with multiple viewports, i.e. using the layout that divides the screen into four quadrants, and in each viewport the camera is zoomed in on a particular part of the assembly. No issues setting it up, but when I play the animation, only the...

    Datum precedence for two single segment location tolerance

    I know that on a composite feature control frame, the feature relating (second row) tolerance must have the same datum precedence as the pattern locating (first row) tolerance. Is this the case also for two separate single segment controls applied to a feature? e.g., could I have an FCF...

    Associative line between two spheres

    Use a CSYS to locate the sphere center, then associate the line to the CSYS. You could try projecting a point from the origin to the outer surface of the sphere, then associate the line to the projected point (or make an offset CSYS to that point).
