Thread: Opinions wanted

BTW- Good luck. CAD is one of my favourite and least favourite aspects of design- when it's cooperating everything is great when it runs into issues then I want to break my computer.

You're definitely on the right track and don't get discouraged. The drawing and design aspect look great. You just need to learn all the ****ing nitty gritty ****ty rules lol...

If you made that I would love to buy it. Unfortunately, I'm sure it will be way out of my price range, so I'll just drool over the pictures.

I started this class a month ago we're starting on autoCad and then I'll be working with ProE and I think Solidworks

If you're going by hard and fast drawing techniques your whole layout is wrong too- what you've got is an orthogonal drawing. So you're gonna want to place the front view (I know this is a "side view" but its called front view, its typically the face with the most detail), then line up the top view and right view so the key points match.
It was this way but I had to move it to fit into a jpg to post here


With regards to dimensions there are two schools of thought. I am working on this right now. I never realized there were so many dimensions in a razor. Not to mention that I added some with the radii

If the spine curve and edge curve are concentric, a slice radial to that circle will give a VERY good view of the blade profile, and will knock out a few dimensions.
Once I get the dimension set I will ask you more about this. Might as well try to learn as much as I can by doing things different ways

Interesting design. Will you be actually producing the razor. It depends on how the drawing comes out. Right now its a project for a CAD class

Thanks for all the input, hopefully I will get this dimensioned and then see what it looks like from there

Thanks Again,

Here's the latest attempt
I think all dimensions are in place but I am not sure if the centers of all the radii should be labeled instead of just dimensioned. The top view has been moved back into place where it belongs. I also straightened out the tip of the tang to make it easier to dimension

Good news- on the tiny rounds and fillets- at the toe, at the point between the two thumb notches, etc- you don't have to dimension the location, just the radius- assuming that they're smoothed into the next feature. Bad news- you have to add vertical placement dimensions to the front view! lol. Also, on the tang angle, I would dimension the included angle rather than the excluded angle- more/better information.

Oh and for some reason- the dimension in the top view from tang-tip to centerline of the pin hole is 2.172, yet in the front view the dimension from tang tip to centermark of the pin hole is 2.177. Three issues with this. First- you shouldn't need/have both on there. Second- if you do, they should be the same number (otherwise you have an issue). Third, if its due to tolerances- a) they should still be the same number and b) the tolerances should be stated.

I know this seems like a lot but you're doing incredibly well. You didn't pick an easy thing to dimension lol. I would try and get your prof's/TA's help on this- face to face is REALLY helpful in stuff like this.

Removing the dimension lines for the radii cleaned up the drawing alot. What do you mean by the vertical placement dimensions, would that be the bottom of the tang to the center of the pivot pin?
The difference of the dimension of the pivot hole was do to someones fat fingers on the mouse the lines were just a bit off as you could tell
Thanks for all your help

Bob

Put in dimensions from a benchmark point (like the tip of the tang) to all of the features vertically- just like you already did for the horizontal ones.

Sorry for seeming to drop this, I am still working on it. We have had a Govt Security Audit at work for the past week and a half. Getting ready for that and working with the Inspectors I haven't had much time for anything. This is over Friday and I hope to post more on this razor this weekend.

Take care everyone

Blimey, CAD takes me back a few years, did a C&G in CAD when our college had the old 386 computers. it was all dos then.

Pics look nice, is a 3rd angle orthographic? (about as much as I remember lol)
