Subtraction problem

[Berzerker]

Take a look at the lines on the corner. That doesn't look right to me.

Here's the drawing

"How to Use the #D Fillet Command in AutoCAD 2007" as posted on YouTube.  Here is the link.  Note: Way up at the top left-hand corner it says AutoCAD 2007 - (Drawing1.dwg).

Something has happened to the solid cover. It's corrupt or something. I tried that yesterday and it didn't work. So, I tried it on another solid in the drawing and it worked.

Now that I know a different way I can easily make it over and will take a tenth of the time.

Thanks ReMark and SLW210

I wish someone had told me this years ago.

One more,

Am I to assume that if fillet rounds edges in 3D that chamfer will do the same at the base of built in spacers? Where I don't have to create a shape, revolve it and then place it and union it?

Chamfer will put a beveled edge on an object.  There will be no voids to fill in or worry about.

Yes, you can chamfer as well.

 

Yes, you have issues with the solid in the drawing you posted. Most likely from trying the subtract and union. 

 

You are correct, you should be able to start over and do a better job.

 

If you hit a snag just ask questions and post the .dwg if you need the solid looked over.

Thanks SLW210

I kinda figured that when it would work on one solid and not the other. Not my first rodeo on messing up a drawing.

There was a knurled roller I wanted to draw in 3D once ... let's just say I saved it a reminder not to try to let AutoCad render to many surfaces in a drawing. it crashes upon start up.

 

At least that was my guess.

Let us know how it comes out and if it 3D prints well.

 

What 3D printer do you use and how do you like it?

 

I've going through various reviews and testing sights trying to determine which to buy, the tech is improving and prices were decent for some well reviewed models/brands.

It's an old Creality and it needs some new parts. You have to baby it, and it takes time to print, or should I say I make it print slow, so it doesn't get confused.  I really like the look of the new enclosed Creality's but I'm not a hard core Creality fan. I'm looking too for a new one. Also $700.00 to $1000* with accessories is within my budget (It's a hobby).

There are some expensive one's out there. The last cover I tried to print on it leaned to one side (also not a professional 3D printer) and it is second hand. But I am used to the software. A little about me I'm 64 and retired. Most my jobs were around machinery. I never learnt electronics, so I started learning because I wanted to remake a favorite from my past. 

This is just one part of that project.

I have a few more post here where you, ReMark and several others have helped me before. Lofting and revolving were amazing tools to learn for a newbie like me. With several corrupt drawing restarts, I got here:

Same age, but working still.

 

3D printing will be mostly a hobby. Grandkids particularly my grandson wants to do some 3D printing. Hopefully that budget works for something decent, I could go more, but wouldn't want to if that gets a reliable machine.

 

That's pretty good work, IMHO.
