Corner blend
Corner blend
(OP)
There has been an active discussion in the PTC Creo community based on the following posting by me last night:
We are trying to model a blend on the corner of a box.
The edges of the box are square, with no blending.
Imagine taking a box and using a belt sander to only radius the corner.
How would you model that in NX?
I don't have access to NX so images only to see what can be done and how easily it can be done in NX.
One of the first replies said to do it in SolidWorks and that was from a long-time Pro/E user. Is SW still Parasolid-based?

Oh and Ben, I forgot to answer your question, YES, SolidWorks is still using the Parasolid kernel, licensed from us, Siemens PLM Software.

RE: Corner blend
John,
After watching the video example you attached, I followed your steps in NX9 and the creation of the "Fill Surface" feature requires that you select "Edges" only. I tried the same thing in NX10 as your example was performed in and the "Fill Surface" Feature now allows you to select curves to create a "Fill Surface". I just wanted to mention this in case someone tries to duplicate your example in NX9.

RE: Corner blend
A more general approach is as follows: suppose you want the corner to be a sphere of radius R.
(1) On each edge coming into the corner, create a tube of radius R
(2) Unite the three tubes. You'll see a point where three edges meet -- this is the point P where the spherical surface should be centered.
(3) Create a sphere of radis R centered at P.
(4) Unite the sphere and the original body.
(5) Do a bunch of Replace Face operations to tidy things up.

> saying "some edge cannot have G1 continuity".
My mistake. I shouldn't have asked for G1 continuity, because that's not what I wanted. I set all the edge constraints to G0, and I did indeed get a spherical face. NX vindicated. But I'd still be surprised if I got a spherical face when working with anything other than planes. I'll try tomorrow if I have a chance.

RE: Corner blend
Well, sometimes it doesn't try very hard. Through Curves or Through Curve Mesh will very rarely (if ever) give a "canonical" surface like a sphere or cone or torus. Have you tried "Fill Surface" with anything other than planes? A sphere-based solution is obviously possible with *any* three surfaces, and it would be interesting to know whether NX bothers to find it.

RE: Corner blend
A bit off topic, but in your movie I can see some "status bar" showing your history actions. Is this NX10 only or also a setting which can be done in NX9 ?

RE: Corner blend
The way you set this up is you first have to have a model where you've performed at least 10 different functions so that the current 'Repeat Command Drop-Down' is full. Then go into 'Customize' and while holding down the 'ctrl' key, drag the icons that you find in the 'Repeat Command Drop-Down', one-at-a-time, starting with the first one and then going in order, from there to the 'Bottom' Border Bar. Once you've copied all 10 icons, leave 'Customize' and remember to save your Role.
Now as you're performing operations, if you wish to repeat any of the last 10, just selection it from the 'Bottom' Border Bar.
Note that you'll have to repeat this for each major application or task that you want to have access to this 'feature', such as Modeling, Drafting, Sheet Metal, etc.
Anyway, have fun

CODE --> Recent_commands_bottom_border_bar.abr
The ".abr" file (above) needs to be located in the "%UGII_SITE_DIR%\application\profiles\UG_APP_MODELING" directory (or appropriate peer application directory) for each NX application that wants to display the border bar. (See "%UGII_BASE_DIR%\ugii\menus\profiles" for the "application names".)
This displays both the text title and icon for each recent command (as shown in John's AVI). If just icons are desired the 10 lines containing "STYLE IMAGE_AND_TEXT" can be deleted. This is compatible with NX 9 and NX 10.
HTH,
Joe
