Hello everybody,
I'm trying to define a spiral spring with a characteristic as flat as possible (meaning a "k" as small as possible), but the "minimize" function of Mathcad don't want to help me... :-)
Please take a look at the attached Matchad 11 file and tell me what I'm doing wrong...
Hello everybody,
I am trying to calculate the max. allowed tightening torque of a threaded collar with given height and specified material and thread size (it is a metric, M10 thread). I have to put the specification of the max. admissible tightening torque on the single part drawing, so that...
Hello,
I have to design a bowden-cable between 2 parts in an assy and I need to create the path curve as a 3D curve, in the context of the assy. To do this, I need to reference on some geometrical elements (edges, points, etc.) from other parts in assy, but I cannot/don't know how to use...
Hello everybody,
I'm currently looking for a good and free viewer for .stp, .igs, 3dxml files with measurement function, which will not need a lot of computer resources, could somebody recommend me something? I have used Teamcenter Professional, it worked, but it led repeatedly to crashes, than...
Hello,
I would like to calculate the necessary section of the support for my 1.2 meter offset satellite dish and for that I need to know how to calculate the "wind resistance" (wind load) of the dish. If I would be able to calculate this "wind resistance", I would use the available datas for...
Hello,
if I am in a sketch and I have projected some edges of 3D solids into it (the 3D solids could be from the same part, or from other parts - if I am working in an assemly), or if I'm just creating a plane in my part, based (referenced) on a solid planar surface from another part in assy...
Hello,
I'm trying to figure out how to scan a sketch at real 1:1 scale, to be able to reproduce the geometrical elements as detailed as possible in a CAD sketcher. For example, if I "copy" the geometrical form of an object (just do the trace of the profile with the pencil on a paper sheet), I...
Hello everybody,
I want to use a wrap spring, pretensioned mounted on a rod, as a brake (to lock the sliding of the rod in axial direction. What should be the calculation approach for the capable axial locking force, depending on the interference between spring and rod, number or spring's...
Hello,
I have a positioning parameter in a product and I want to modify the value of it only in 10 mm steps, so I'm using the "change step" option in the contextual menu and everything is ok. But if I close my product and open it again, the changing step of that parameter is again 1, as...
I'm impressed of the functionality of Working Model 2D, but I wonder if there is a similar software which allows a more precise definition of the elements: for example, I would need a parametrical definition of the elements, with dimensions for lengths, widths, position of pin connections, etc...
Hello everybody,
I change the "working directory" in the ProEngineer WF4 and it is ok until I exit the software and start it again - than I have to change it again, because, for some reasons, it will not keep the modified informations. Is this a bug, or I am doing something wrong?
The second...
