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

I think the OP retired for the night and it's just two guys having a friendly discussion.

I think the OP retired for the night and it's just two guys having a friendly discussion.

 

 

Nope...just been dragged into other parts of work.

 

Thanks for all of the advice, I am still confused as to how to get it to work...so I will bring it up with my tutor tomorrow night and see if he can show me where I am going wrong.

 

I do agree that it is a good way of picturing the process as in taking materials away rather than adding what has already been taken. At the moment, I can get the chamfer to appear, however there is still a step from the smaller diameter tube to the chamfer.

 

 

Thanks for taking the time to help...I think I need to get a little more experience at the moment.

The solution is simple. Don't specify a chamfer larger than what you have to work with either horizontally or vertically. You only have 1.25 to work with. How does one apply a chamfer of 3 if that's all you got?

Sorry to be a pain...could you just give me some pointers as to which faces etc to click. At the moment I am using Chamfer, and then selecting the edge highlights the outside face of the 22mm diameter section. It then asks me to specify the base surface chamber distance What is that?

[ReMark]

You are going to click on the outside edge of the cylinder with the largest diameter...twice. Once to start the command. Now do NOT touch your mouse! At the next two commands input the distance of 1.25 then at the last prompt pick the edge you first picked. Done.

[ReMark]

This is what it looks like at the command line.

 

Command: CHAMFER

 

(TRIM mode) Current chamfer Dist1 = 2.7000, Dist2 = 2.7000

Select first line or [undo/Polyline/Distance/Angle/Trim/mEthod/Multiple]:

Base surface selection...

Enter surface selection option [Next/OK (current)] :

 

Specify base surface chamfer distance or [Expression] : 1.25

 

Specify other surface chamfer distance or [Expression] : 1.25

 

Select an edge or [Loop]:

 

Select first line and Select an edge are the SAME object!

One thing that may help is knowing precisely the dimensional size of the existing geometry. Before starting the chamfer command do as one poster replied: view your model in isometric. Set your decimal precision to as large as you can then issue the DISTANCE command and measure from one quadrant to the other. This will tell you the maximum distance of the chamfer you can specify.

At this rate I think it is almost time to put the CAD into a box and take it back to whence it came from!

 

 

I have followed what you said and it didn't work...so I have taken some screen shots of doing it. Is this correct?

[JontyR]

just tried your method you have gone through...and it works

 

 

So just need to keep trying to recreate it and hopefully it will start to stick in this brain of mine!

 

Thanks for all of your help

 

Now to try and stick on a thread....There isn't anything on here that does that as standard is there

Honestly, you are making this way more difficult than it really is.

Switch to a 2Dwireframe view. Start the Chamfer command. Now ignore the command line and make your pick as indicated by the red arrow in the image below.

 

Follow the pick by pressing the Enter key once.

Type in 1.25 and press the Enter key.

Type in 1.25 a second time and press the Enter key.

Select the same edge and press the Enter key.

Done.

You sir are a scholar and a gentleman!

 

 

Thank you muchly!

What was the intended units for this part?

38.3 Meters center-to-center distance on the holes?

That sounds too big even for ship building industry?

[ReMark]

I'm a thick-headed, stubborn Irish-German-Czech who does not like to fail.

 

Now that you have done it (YEAH!) do you understand the command any better?

[JontyR]

Yes I do....so thank you. I do have a degree in Maths...so although I might have appeared a little on the thick side...I am reasonably clever

 

 

Just need the practice, so I am getting all of the parts that have been designed for us, and trying to model them. So thank you for helping me along the way

[ReMark]

You're entirely welcomed.

The units are in mm, and so the total height is 67mm and the width of the flange is 53mm

 

 

Well at least that is what I believe I put in there.

[JD Mather]

The units are in mm, ...

 

Type -dwgunits (with the minus - sign) and hit Enter.

Read the command line, what does it report as the current units?

 

Oops, never mind - I just checked again and got mm.

Not sure what I did.

My fat fingers must have hit 6.

good to have more tips on how to look things up

 

 

Sooooooo much to learn!

 

 

Found a good tutorial on how to construct a thread...so that is tonights homework

[JontyR]

Finished the part

 

 

Redrew the part using imperial as the thread is an imperial thread. Always good to do it again, just reinforces the techniques.

 

Thanks for all your help...Will start the next part shortly.
