Thanks Ted. I do have that chart in my ref matl. I did not mention that this is carbon/resin layup using carbon fiber and M87500 and MTM45 among others. The chart that you referenced shows carbon as excellent. It is the resins that concern me. Anyway thanx for the input. Jerry Jerry L. Eden...

I am currently working for a company in Mojave as a Landing Gear Systems Engineer and have a question regarding Skydrol and what effects it has on composites. I have been searching the internet intensely and have not found much info on the subject. The direct question is that I have a 75,000...

Here is an addition markup that helps explain what I am looking to change. It is a power point file. thanks, Jerry L. Eden Sr. Design Engineer Catia V5, SolidWorks, NX2-6http://files.engineering.com/getfile.aspx?folder=5cd342a5-bcdc-4f53-a5d9-fad10c2bb25d&file=DIM_OVERRUN_LINES.pptx

Kevin, Thanks but I was refering to the dimension line. If you look at the arrowheads on the outside of the dim there is a short line on the inside of the dim close to the text. I want to be able this line altogether. I cannot mark it up I do not have the tools. thanks for your help, Jerry...

Hello to all, I am trying to set the dimension callout so that there is no extended line with arrows out. I attached a file that shows the dimension but I want to eliminate the short overruns of the dimension line on the opposite side of the arrowheads. I know that CATIA does this by default...

ferdo, Thanks for the help. Jerry

Hello to all, My next question is a CATIA question. I know how to appy material to the part body but what I would like to do is to have the material to be visible on the part body. Hope this makes sense. CATIA V5 Rev 19 thanks, Jerry

Thanks to all who replied. I finally found out the answer. The S.R. does mean spherical radius on the drawing. Although not per spec the S.R. meant that the spherical radius was a concave radius. This is used for feel so that it creates a "feel" so that the finger can find the switch button...

Thanks very much too all. I did not think this would get that much attention. The answers are great and helps to have more ideas from everyone. This particular part is from an SCD and has no cross section view, just a top and front. We are trying to finalize a RFQ and we just did not get enough...

I just want to thank everyone for their thoughts on the problem. And for monkeydog I do not think it is a sperical radius because it is pointing to a flat surface. Typically it is called out as SR 1.00 and not S.R. 1.00. It could be a typo and a geometry error. All of the answers were things...

lisa247, The SR is just an abreviation for Senior Design Engineer. I have over 30 years experience in aerospace, aircraft, and spacecraft. I am 63 so I guess I am SR citizen also. Jerry

MintJulep, The Company, Aircraft, context, Drafting system, etc is not relevant. I have been in this business for over 30 years and am an a consultanting Sr. Design Engineer. I have looked through all documentation to try and find out the meaning without success.I am attaching an env dwg of the...

I have a drawing that is calling out S. R. and it does not refer to a sherical radius. It is on a Test Enable switch which is on a Thrust Reverse assy. Thanks for the help in advance. Jerry Eden

I know this has been talked about before a few months ago but I would like to resurrect the topic. I want to have a crosshair in my graphics window and was wondering if anyone knew how to change this option? Thanks in advance, Jerry

Wow. This is a great discussion. I really appreciate everyone's input chimming in on this one. I did not think there was this much interest. That is what is great about this forum. It sure is good to see the varied disciplines. I do have to agree that there are a lot of factors to come up with...

Thanks guys. I appreciate the help. I know that at Boeing I think we used 2D + .062 and composites 2.5D +062 same as SWComosites pointed out. The reason for the question was that someone here said that there was an Industry standard out there that could be referenced. I was not sure so I went to...

I am looking for an Industry standard that calls out the edge distance of fasteners. I was wondering if there is anyone out there who may know of the spec? Thanks,

israelkk, Thanks for the help. After some research it did appear as you said that the seals should be okay as is with some minor changes as long as the system is lubricated and conforms to surface finishes. We are re-plumbing the entire aircraft from scratch and this was part of a trade study...

israelkk Thanks for the prompt reply. We are going to store the nitrogen in a storage bottle. On the current modified aircraft there is already a nitrogen bottle for emergency extension of the gear and operates the gear doors also. We want two additional bottles to work the extend and retract...
