First post...looking for help with the solid edit

[JontyR]

Hi,

 

 

This is my first post, and I am trying to model an oil tube. I have added a picture. I extruded the first tube out by 67mm and then using the presspull tool removed 27mm to end up in the position you see now.

 

 

what I am trying to do is to add a chamfer in to fill the gap, but I am getting lost!

 

 

I have used SolidEdit and then selected the face that is out of view ie the step

 

 

I then select extrude and enter the height which is 4mm and I think the angle is roughly 30 degs. What it doesn't do is join the two surfaces together. Can anyone suggest a step by step way of doing this?

 

 

Cheers

Not sure where you want to apply the chamfer, but the built-in command CHAMFER may be of help. You will need to play with it a little to understand how the base surface concept works.

Thanks for your reply. I have tried using the chamfer tool, it is just getting my head around as to which faces/edges I need to be clicking on. I have, I think, tried most of the combinations...but it just isn't working out!

 

 

This is what I am looking for

 

 

Likewise I am trying to do the ChamferEdge on the end of the neck. I have watched a tutorial, albeit in Arabic! and they just click here do this and hey presto there it is.

 

 

I do it...ChamferEdge d (distance 1) 3 (distance 2) 3 select edge and it appears but then when I press enter it just tells me failure whilst chamfering

 

Getting confused!!

Attach a copy of the drawing to your next post and someone here will take a look at it.

Welcome to CADTutor.

 

The CHAMFER command removes material in order to creat the chamfer.

I suggest you choose an ISOMETRIC view of the item, and try again,

it is much easier to make your selections when you can see more axii and faces of the object.

[MSasu]

You may achieve that result with CHAMFER by setting one chamfer distance equal with the height of that transition (the red part in your sketch) and the other with half of diameters difference. Just pay attention at their order.

As stated by Dadgad, this command will remove material, so the big cylinder must be longer with length of transition part.

Did you say there was a "gap" between these two cylinders in the area circled in red?

[JontyR]

There is no gap per say, all I want to is put a fillet in as such

 

 

Getting so confused here

 

 

 

Watched a good video, and he uses the chamferedge...now I believe the reason I am not able to do this is that I have gone beyond the width of the top face. There is a hole that runs through the centre of this. On the video he just clicks distance (Start around 8:08) and then starts on the edge and moves out, I have tried this and it just enters in 1 or 6 something. I have put polar tracking on, and taken off the snap to on both 2D and 3D

You're making my head hurt. Can you just please attach a copy of the drawing to your next post?

[JontyR]

Sorry for making your head hurt

I was able to chamfer the two pieces. Why? Because I did not make the chamfer distance larger than the distance I had to work with. Ex. - If the distance from the O.D. of the outer cylinder to the O.D. of the inner cylinder is 2 you can't make the chamfer 5. Follow me?

[ReMark]

My chamfer. BTW...I used 1.25, 1.25 as my distances.

[ReMark]

Chamfer distances of 5 and 1.

[Patrick Hughes]

Try making the chamfer before you make the smaller dia. portion. You are getting a failure because when chamfering (or filleting) you need a remaining surface. It's like Remark stated above.

[ReMark]

You do? I had 1.25 to work with. I used 1.25 and it worked. Now if I had used 1.26 then it would have failed.

[Patrick Hughes]

I admit to shooting from the hip on my statement. But I try to avoid potential problems like that.

[Patrick Hughes]

BTW, think about how a part would be machined. In this case a chamfer is removing material from a length of round stock. in your second image you show adding a chamfer when in actuality you want to remove a chamfer.

 

 

Edit: Sheesh, I should read and reread all the posts.

[ReMark]

My point to the OP is you can't go beyond what you have to work with. In this case his "collar" (where the two cylinders overlap) limits him to 1.25 in the horizontal but he has much more than that to work with in the vertical as my second image demonstrates. Shooting from the hip is fine just as long as you don't shoot yourself in the foot. LoL

In this case I don't care how it is made just how it appears in the drawing.

That was directed at the OP.
