My heat transfer is rusty at best. We are designing an oven that has 600 F internal cavity temperature. The oven door is constructed of stainless steel with 2 glass panes. The glass panes are seperated apart by 1/2" air gap. We want to solve for the surface temperature of the outer glass...

Thanks FeX32. That's the most detailed info thus far.

Good info. Some I've seen before, but don't really get down to the nitty gritty of actually designing one from start to finish. With 4 bars, there are certain graphical techniques that will determine where all the fixed and moving joints will be. Wasn't sure if there was a way to do 6 bars...

There are all kinds of graphical methods to construct 4 bar linkages. Is there a graphical means to construct a 6 bar linkage? Is it more or less trial and error / experience? How do you know where to place the joints to achieve the movement desired?

I knew I could count on you guys! I didn't have my snap point selector on. Been trying to figure out this one all morning! Thanks.

This one aways kills me. When you go to edit some features, why doesn't the same interface show up as when you first created the feature? Also, some of the original options are greyed out when you edit! For example, when I edit a trimmed sheet, it won't allow me to change the original...

I am having trouble making a domed surface. The surface is supposed to look like an egg split in half lengthwise. I have curves defining the outside oval shape and curves defining the front and side profiles. What command do I use? In NX2, I would use 'thru curve mesh' to pick the outside...

I see your point about the design intent. This verifies that my conversion was successful then. Thanks.

Need help with converting units from metric to inches. I tried using the 'ug_convert_part' program from http://www.vickers.de/ugconv.htm. This works fine, but my sketch dimensions and other values stay in metric. I'd like all the values to be changed to inches. Is there another way to...

When I add an existing part to an assembly, all my layers and blanked objects show up. But when I display the part, only the solid geometry is visible. What am I doing wrong? Also, how do I change the units in the part, I need to convert the part from mm to inches.

Yup, that's what I had to do - reposition each one at a time. Thanks.

Copying and pasting was the only option that worked. This just seems very tedious, especially if there are many features to be arrayed. Grouping the features and array the group still doesn't allow the group to follow along a specified path. With Pro/E, I can constrain the feature(s) on a...

Here's another challange for the UG experts. I have an s-curve projected onto a compound surface. I'm trying to create a feature pattern (in this case, 5 dimpled cuts) that follow the s-curve. The instance command does not allow for such a function, does it? Or do I have to make them all...

Thanks PhilJenkins for the response. I guess I was constraining the conic to solid lines instead of construction lines. It makes no sense why UG can't differentiate the 2 line types, but it worked.

Okay, I found a way to do it. Sketch 2 unattached lines. Then use "bridge curve" to connect the 2 lines together. Then extrude the new curves. That was easy...

Here's another UG gripe. I need to create several curves that are thru 2 points, but the endpoints have to be tangent to their adjacent surfaces. I'm looking for a command that is similar to "bridge curve", but specifying surfaces rather than curves to be tangent to.

I tried what cowski mentioned. The part is basically a 1/4" thick, quarter-circular tube (6" radius x 10" high). The one side I am trying to apply the conic to is arced (not straight). Because of its circular xsection, face blend seems to be limited on how dramatic the conic can be. Maybe...

How do I create a conic feature in sketcher? I need to make a radius'd corner using a conic instead of a round blend. The shape is basically a tall rectangle, with one side having a slight arc. When I try to constrain the conic in the sketch (tangent to the arc and line and coincident to the...

Actually, we just found in NX2 sketch mode, you can add associative points. But it's in sketch mode only. I'll have to try this to see if it really works. Thanks all.

I have other curves attached to the points which help me define the surface more accurately. Here's a simplistic example off the top of my head: I have 2 parallel curves and at each end of the curve is an arc section connecting them. Now I put a .25 U parameter point on the parallel curves...
