Hi all, I wanted to ask your opinions on the best practice to make a nest/setting jig for a part of irregular geometry. I am currently tasked with this for a lot of parts but I am not sure what the most efficient way to go about this in NX is, two lines of thought currently are: Extrude...

@Dawson70 - Thats interesting, 100% of sketches made in 3D space. So if I understand, 3 planes, 3 3D sketches on them planes, and then smooth curves in space between planes then use tube feature. I wonder how I would join each corner, optimizing this for 3D printing.

For reference this was the result from sweeping and patterning. The corners do not fully join and I can't figure out how to extend if that's necessary.

@Dawson70 Thanks for the reply. I cannot open the file (error: this is not a part file). I suspect it is a version issue (Running NX 9.0) I attempted sweep, it worked well but still ended up with corners being an issue, after patterning I have 1 corner which fell short and did not intersect...

Thanks for the tips, So I created the three sketches across three planes. Sketched a curve in 3D space. Attempt to use the tube tool, get an error: Gaps in string, I am stuck. Any suggestions? I think I will try sweep along a guide.

Wanted to produce this 'light shade' ornament thing. I am a great novice at CAD, my steps to produce this were as follows: Sketch circle Offset Create Datum/Plane above circle Sketch Hexagon Offset Repeat for Upper Level This is where I am stuck as to what the most efficient approach is...

Hi, I am wondering if you can edge blend between two intersecting features. In the image attached you can see a sweeped handle against a surface. This is intended to 3D print but I cannot edge blend the point at which the handle intersects with the surface. Is there anyway arround this...

So I have a body of a door. The blue shaded area is where a badge should be. I need to replicate the curves of the door, and produce a setting jig for the badge x mm from the side and y mm from the bottom. I tried untrimming but really not sure. Any help apreciated.

I am in the process of designing a setting jig yes. Can't share photos. For example, I need to match a badge/logo to the back of a chair, the back of this chair is curved and the badge must be fit against the headrest. All parts are referenced from the front centre of the seat. How do I go...

I am wondering what the best process for matching the contours of a surface in order to produce a setting jig are. Something like a badge on a car door for example. I was thinking: - Create a plane perpendicular to the farthest point of the surface. - Sketch on the plane. Extrude to...

Ok thank you, so for the use of roarks formula, the frequency is given in Hz right?

The only dimension should be T-1? I don't follow. I don't think roark is wrong, there are just a lot of opinions on which formula to use. A MIT spreadsheet for beam frequency I found suggested I use the following equation: https://gyazo.com/dda4d2cc79a8376b17f3d00490483006 where k = npi...

I have been trying to find some formula to follow to calculate the frequency of a simply supported beam for some time and there are so many suggestions I am not sure what to follow. I have a beam with 2 point loads, equidistant from the beam supports and, a uniform distributed load across the...

The following picture shows the formula I am following for natural frequencies. This doesn't take in to account mass does it? The values for natural frequencies vary hugely compared to ansys.

The current beam has loads at 1.5m from each support. Is a = 1.5m, or the mid-point of the beam?

Thanks for clarifying that. Much appreciated.

On a seperate note, is this method of superposition applied to finding the natural frequencies of a beam such as this as I can only find formulae for beams with point loads or uniform loads, not a combination.

https://gyazo.com/166343a6b10ccf380eefd975b1565a56 So that is the beam. It has a cross section of (0.3x0.35m) Am I correct in thinking deflection is as follows: 2{Pa(3l2 - 4a2)/24EI} + (5wl4/384EI) or do I just make P the value of the sum of the point loads? This help is really...

@BARetired, is that the overall equation or the deflection at 1.5/3/4.5? I worked out deflection to be ~6mm however, ANSYS modelling suggests it should be arround 14. Of course there may be error in my model on ANSYS.

Cheers, I will look in to superposition. The beam is 6m long, Point loads at 1.5m & 4.5m and a distributed load across the length. Should I calculate the deflection at 1.5m with the point load and multiply it by 2 or calculate deflection at 1.5m and 4.5m seperately?
