I have 2 parts to be assembled. - I add the parts to a product file and assemble them using Assembly Constraints(3d constraints) - By using 3D Constraints, I reorient one of the parts with respect to the other. But this 'reorientation' is only happened in the product. When I open that part in...

Hi, I am trying to model a simple container structure using CATIA Structure Design. When I try to create shape, in the section entry, I select 'other section' option, then the catalogue browser opens, there is only the AISC Resolved Catalogue, but I want to use DIN Profiles, there is a DIN...

Cheers, I want to model a bungee cord to apply force to a sledge like body. The problem with the bungee cords is a bungee cord cannot be compressed like a spring. It only exerts a pulling force when extended. I would be very pleased if you can help me on how to model a bungee cord

I would be very grateful if someone tells me hot to make the icon of a spring smaller. I tried everything in its appearance menu in vain. Regards

I have used NX Human module to create a human. It worked fine and now I have a human model. The problem is the model consists of segmented 'faceted bodies'. I have searched the forum for faceted body, and according to the threads, I understand that there is no way to convert a faceted body to a...

In one of our ongoing projects, a customer of ours have asked about landing gear g-meter. I said we would look into that, but I could not find an application so far. This g-meter should record the vertical deceleration of the landing impact on the strut. I would be very glad, if you can...

As far as I know, giving the analysis-->distance command allows us only 1 distance measurement. After I get the results, the interface turns off. I am really bored of giving the distance command repetitively. Is there a way of measuring multiple distances using the same command? Regards

I'm sorry if the title doesn't make any sense. The explanation is as follows: - Suppose we have a bunch of parts to be assembled. - We add the parts to an assembly file and assemble them using mating relations (3d constraints) - By using mates we change the postions and orientations of the...

Suppose, we have an extrusion feature already defined... The sketch of the extrusion is placed on a previously defined Datum Plane. After a while, we wanted to change the placement face of the existing extrusion to another datum plane defined later on. How can we do this? Thanks in advance?

I created a model with a planer body fixed on ground and another body with a definite height above the the planar body and applied a contact between the two bodies with the impact option. The suspended body is allowed to fall on the planar one. I want to measure the force between the bodies at...

I want to rotate a complete assembly in 3d with mating relationships already defined. Such as rotate all the components in the assembly around XC axis with an angle of 90 degrees at the same time preserving the mating relationships thus maintaining positions of the components with respect to...

In the previous CAD software I used, when creatring an assembly, the software automatically defines the first part added to assembly as the Base Part (or Ground Part). The term implies that base part has no degree of freedom, or in other words fixed in space. Thus by mating other parts to the...

I want to verify (or validate) ADAMS' AutoFlex using a simple beam under torsion. Suppose a circular cross sectioned beam with a definite length (My example was Hollow Section with Outside Dia: 60mm; Inside Dia:40mm; Length:1.5m). One side of the beam is fixed. The other side is under a torque...

Suppose we have created a rectangle in sketcher and then extruded the sketch. Afterwards, when we double click on the sketch of the extrusion to edit and want to delete ie the top line and replace it with two angled lines making something like a roof shape, UG NX2 says I cant delete the line...

I will be glad if someone tells me the meaning and/or usage of the '!' mark that sometimes comes after the file names... Best regards

There should be a parameter about the precision of the 3D constraints. Suppose there is an off-center value of 1E-6mm in any direction between a shaft and a hole. One can still mate these two bodies regardless of the minimal off-center value. In Mechanical Desktop there was an assembly...

Hi, I've been trying to udnerstand the spring gear design example in Norman Currey's "Aircraft Landing Gear" design on page 87 without success. I began thinking of something amiss in the example. By the way, anybody heard of K. S. Coward's methodology in "a very old issue (date unknown) of Aero...

Hi I want to set the background color to black and all foreground material (text, math regions, annotation etc.) to white for better eye health. How can I do this? I cannot change the color of math regions. (MathCad v12) Best Regards

Suppose I have a function wrt time such as: f(t)=Asin(wt) Both A and w are known. I need the maximum value of f(t). To do this I can take the derivative wrt t then equalize zero and find the value of t; then substitute this t into f(t) and I get what I want. But a simpler approach may be to...

I need help solving this equation for c1,c2,p1,p2: (2 4)T=c1.(0.732 1)T.sinp1+c2*(-2.732 1)T.sinp2 (0 0)T=w1.c1(0.732 1)T.cosp1+w2.c2.(-2.732 1)T.cosp2 T: Transpose (.. ..)T: vector w1 and w2 are known Any help is greatly appreciated. Regards
