The following vibration spec came across my desk almost on a cocktail napkin.
Vibration/ Shock Spec:
Frequency Range: 10Hz to 40Hz; amplitude = 0.1” p-p
40Hz to 2000Hz; acceleration = 4g RMS
Frequency Period: 30 minutes; 10Hz to 2000Hz and return
Test Time: 3 hours...
Hi,
I'm interested in properly specifying the bore for a keyed sprocket hub. The 2" sprocket will sit over a 3/4" drive shaft that rotates ~3rpm and ~1000 lb load. Everything has been sized except for the fit class.
I have just about exhausted my internet resources looking to find which...
Hello,
I noticed ASTM F852-99 on the side of my rubber maid gas container and am now curious of the regulations.
Is anyone familiar with ASTM F852-99 standard for portable gas containers? If you've ever run across it, what are the main requirements of the standard?
Thanks
Tom

Greetings Civilization,
I've just noticed that on some assemblies, after I close the viewing window, there are still additional parts open that I never opened. These parts belong to the assembly that I just closed. I'm assuming these parts automatically opened when I open the assembly. Does...
Hello World,
The part shown in the link is a hinge block. It is to be sent out for fabrication. I’d like to dimension the pin hole in such a way that variance occurring to the width of the bar stock will not cause the pin hole to be off center due to the fact the pin hole is dimensioned from one...

I have created a SW Assy BOM that, isn't Excel based composed of ruffly 70 components. Our MRP system BOM has gaps between the positions of these 70 components yielding a non-consecutive BOM e.g 1,2,3,6,7,8,12,13. This is caused from previous engineering changes...
Hello All,
Hope subject describes problem. Looking for an option so that my exploded sketch lines are visible even when routed behind/between components in my drawing. The best I can do is to select the whole drawing view for Hidden Lines Visible. But I would prefer not to have every part's...
Hello All,
I have a flat pattern with two symmetric holes that will be bent into a symmetric channel thus making these two holes concentric.
As far as the drawing I'd like to specify the two holes as concentric. From my understanding, to accomplish this I'd have to assign one of the two...

I did a Save As to duplicate an assy that needed some changes.
I swapped out 3 major sub-assys and due to plane orientation inconsistencies between the old and new sub-assys, remating and repositioning of the planes were required. So after editing...
Greetings Again Everyone
I have an assy of sub-assys and components. I'd like to replace sub-assy "A" with a sub-assy "B". A & B are almost identical sub-assys. Upon my first attempt of Replace components, B ended up almost in the twilight zone without error messages might I add. So I compared...
Hi all,
SW05 :(
I have an assy with sub-assy's and components. I have managed to create a drawing with a BOM embedded in the drawing that displays my assy tree just the way I desire it to. The kicker is, the balloon item number callouts on the drawing don't correlate with the BOM embedded in...
Hi all,
Anyone have a quick web reference for determining how deep to drill with the "pre-tap" drill before tapping, given the depth of thread required? Typically I use hole wizard in Solidworks, but it would be great to have some sort of table to understand.
Thanks a bunch

Hello World,

Anyone ever had this problem?
Opened an existing exploded view Assembly which contains sub-assys. All is fine except for one sub-assy. This particular sub assy has about 6 explosion steps, but on the very first step to bring it out from the main assy as a sub-assy...
Greetings,
I have an application in which the shank or unthreaded portion of a Gr5 3/8" bolt is used as a pin for a member to rotate about. Well the design has changed so that the bolt has shortened (~3/4") and most bolts of this shorter length are fully threaded. Like I said it is a pin...
Hi,
Im looking to split the surfaces of a bolt to seperate the shank and the threaded portion of the bolt. With two surfaces I can add an appearance of a thread to the end farthest from the bolt head. I tried creating a plane offset from the tip of the bolt and then sketched a circle as the...
Here's the situation I'd like to analyze. A torsion spring with one of the straight spring legs resting flush against a sheet metal flange, the other...well I dont think it has bearing on potential discussion. This spring leg should deliver a triangular distributed load from torque: Zero above...
Hi,

For some odd reason the form tools in the design library will not work on my flat sheet metal part. When I drag the form onto a face of my part the message "Is this a derived part? Yes/No" appears. After clicking yes a locating window pops up for translation/rotation...
Simple Assy consists of a shaft, collar and a rollpin that keeps the collar rotating at the same speed as the shaft as well as prevents the collar from transposing along the axis of the shaft. Therefore there is a hole drilled through the collar and shaft that the rollpin fits into. Id like to...
Hi,
Currently I have a shaft that has a limited rotation from +90 to +15 degrees. Clamped to the end of the shaft is a cam that engages 3 different on/off switches which lead to a "pc board". Each location of the 3 switches can be adjusted via screw, which is how the mechanism is callibrated...
Hello Fellow CAD Jocks,
In a SW05 drawing you can have multiple views with several annotations locked to different views. With this, dragging a view will move all notes, etc that are locked to the view along with it. Is there a QUICK way to lock an annotation to a different view other than the...
