    create geometry from point cloud

    I have some 2d geometry that I need to import to Abaqus. I generate my simulated structure using a Matlab script. This gives me points that define each geometric shape (circles, rectangles, and triangles). Currently I import these points into NX and export the defining lines as a step file. Is...

    2D mesh failure with randomly oriented pieces

    I'm having trouble meshing a 2d geometry with randomly oriented rectangular pieces inside of a matrix material. I get very good meshes when the internal rectangles are aligned, but the mesh always seems to fail with the randomly oriented pieces. Does anyone have any recommendations?

    NX macro help

    Hi, I need to generate surfaces on a bunch of shapes which I have imported via spline from file. Some are by poles as they are rectangles and triangles, and some are through points. I am able to use macros to pull in all of the shapes, and to create surfaces on the circular shapes using the...

    fea training resources

    I'm starting out using FEA to do some simulations in a university research setting. I am using hyper mesh 11 as a mesher and abaqus as a solver. I'm having trouble finding good hyper mesh resources. Also does anyone have any good resources for learning about FEA in general? I'm having trouble...

    adding standard tap/screw sized to NX

    Yes you are correct it seems to be a units issue. My part is in US standard, but I needed metric screw holes. This may be a bug with nx 7.5 since I have selected millimeters in the style dialog of the dimension. Unless you have a suggestion on how to fix this issue I will do these callouts by...

    adding standard tap/screw sized to NX

    I was able to add my new thread sizes, but I'm running into a different, related problem. When I add the callout into my draft using a feature parameter a M4 X .7 hole comes through as M4 X .03 I checked the thread hole standards XML, but this .03 value doesn't seem to exist. How can I get my...

    adding standard tap/screw sized to NX

    Hi I am working on a project where I need to use metric tap sizes that are not in the standard list of taps (when creating a tapped hole feature) included with nx 7.5. I would like to append the NX default data with some standard sizes that I use frequently. Does anyone have any experience with...

    importing 2d points to hyper mesh

    Hi, I have a list of 2d points generated from a matlab script which simulates the micro structure of a material that I am working with. I need to do a high fidelity mesh on this. How can I import these points into hyper mesh?

    creating a metric clearance hole in a standard part

    The option has showed up. When I first tried to use it it just gave me iso or ansi as an option. thanks!

    creating a metric clearance hole in a standard part

    I'm using NX 7.5 and I want to create a metric clearance hole on a part with base inches. I haven't been able to find an option to chose what standards in the hole creation dialog.
