I'm making my head hurt because I think i'm making something harder than it needs to be. I have a Circuit board that interfaces with a heatsink through two pins (part of the heatsink) with a hole (Datum B) and slot (Datum C defined by the width). There is a pattern of holes (two Ø.118 and 4...

Guys, I'm trying to think of the best way to dimension from holes which sit on an angled surface to my A|B|C datums. I've attached my first shot, which I think is correct up to the part where I label the edge of my angles surface 0,0. How can I cleanly ordinate dimension the holes...

Guys, I have what I think is a simple question but Google couldn't even answer it... If one is using ordinate dimensioning and you have multiple surfaces that are co-planer and represent the "0", how do you show that on the drawing. Perhaps more info is needed... I know if I wanted...

Had a simple question, I think. Imagine I had a plate with four holes in it, don't really care about the perimeter of the plate, just the position of the four holes relative to each other. Currently I have the bottom of the plate as datum A and the far left hole datum B (with a perp. tolerance...

Guys, I've read a couple posts here about surface profiles with no datums but I'm still a little confused. I found this post by Jim (MECHNORTH): By "best fitting" one can shift the workpiece about its 6dof to find the best fit of the workpiece within the maximum & minimum boundaries (i.e...

Guys, Ran across a situation that I am unsure of. Is what I show in the picture legal? Specifically can I call out datum D (plane representing the centerline of that dimension) and then use that same datum in the control frame for a profile of that same feature? I was asked to do...

Guys, I am working on the drawing for a plastic injection molded part and am running into an issue. How can I put datums on surfaces that have a draft angle to them?

Guys, I am designing a small container, ~ 4" x 2" x 1.5" that can hold liquid without leaking out. This device basically consists of a base that has a lip around the perimeter and a cover which fits over that lip making a tight seal (think of a typical plastic tote you use around the...

Here is a question that I am having trouble finding an answer to... Say I had a rectangular block with a hole in it. If the block was laying face down I have the bottom as datum A, one of the four sides would be datum B and the hole datum C. Datum A has a flatness tolerance but my question...

Hey Guys, I have a problem which I believe is simple but I am having a hard time figuring it out in my head. Basically what I have are two pins (.018 ±.001). These pins gets inserted into tooling which have holes of .020 ±.001 positional of .004 So now I have these pins set in the...

Hey guys, I'm trying to get a list of about 4-5 big changes that you would see between the old ansi y14.5m 1982 and the asme y14.5m 1994. I know it's probably dependent on the drawing but i'm just looking for the big obvious changes. Thanks, Pete

Hey guys, I have some square tubing modeled up and bent at some angle. I need to find out how to show the plastic deformation in the bend. I've been trying to use the warp tool but haven't gotten anywhere.

hey guys, I am trying to figure out a torque problem. Say I have a torque wrench that is connected through a ball and socket joint to the socket. So the torque wrench is at angle to the normal of the socket. How can you calculate the torque getting to the socket? This seems like it is...

hey guys, i am working on a device that will be placed on the hot coolant hose that goes into the radiator. So the hose will be split and the device put in between. I am modeling this in flow works. The problem I am having is all I know is the coolant velocity in the hose. I need a pressure...

hello, I am working on this two piece system, a cylinder and then a female part shown below. The extruded cylinders on the female part ride in the swept groves on the cylinder I have been trying to get this to work in cosmos motion but am having problems using the contact feature. I...

hello, I am working on doing this analysis of a swing arm, which is the rear suspension of a vehicle shown below. I am trying to simulate a worst case scenerio for a FEA which would be the vehicle falling and landing on just the rear wheels. Im not quite sure how to calculate the loads...
