press/pull feature

[Frana]

Simple question, I hope...

 

Moderately new to the 3D modeling. Just learning on the fly.

 

Came across an issue I can't find the solution to.

 

I have created an 1 1/4" cylinder, 10" long. I would like to basically "drill" a hole through the side of this, for like a locking pin.

 

I can't seem to press/pull the regened circle through, because it's not recognized against the curved side of the cylinder? I can easily pull a hole through the top of the cylinder, just not the way I need to.

 

Any help is appreciated, thanks!

Probably need to rotate ucs so z is pointing in the direction you would like to press/pull. you can use ucs 3 point or type ucs enter right or left.

Extrude and Subtract if presspull doesn't work.

I agree with Wookworks, you need to rotate your UCS as you will be extruding in Z direction, this is why you can do it on the top but not the side

Press/Pull will work. As previously mentioned the key to its success will be the orientation of your UCS as demonstrated below.

Thanks for all the help.

 

I only work in respected top,btm,l & r... views for coordination to my drawings. As for any sort of modeling adjustments, I found that using the correct USC isometric views are far more beneficial. So, this didn't seem to be my issue? Using a 1 1/4" block with the same methods I've been using, allows me to press/pull this hole through. But there is something about the cylinder? Probably the fact the there is, in some scientific, mathematical, most insanely factual explanation... literally only one point that physically touches the two opposite planes? Funny is all.

 

Good point of my rambling is that I didn't realize that you could add/subtract 3D objects as JD suggested. So, thanks! This method worked out great! This is a beneficial approach for future drawings.

 

I truly do appreciate all the help, and in such a timely matter.

"But there is something about the cylinder? Probably the fact the there is, in some scientific, mathematical, most insanely factual explanation... literally only one point that physically touches the two opposite planes?"

 

And this "anomoly" applies to only one person in the world who just happens to be you? Sorry, I don't buy that arguement. Pure and simple...you did something that wasn't quite right and AutoCAD would not let you get away with it. Question. Do you work in conceptual visual style exclusively?

[Frana]

I jump between 2D wireframe and conceptual.

 

As for the steps I took to create the drawing of the cylinder above...

 

2D wireframe. Top view. created a circle, regened it.

Flipped to conceptual, used the shift/middle mouse button to rotate slighly. Extruded the circle to 10"

Then flipped to front view. Used the shift/mmb to rotate again to a view that is basically what the picture shows.

Created a circle, using object tracking off the top/ctr of the cylinder for a reference to locate the point of insertion.

Regened the circle, tried to press/pull.

 

All of which I did the same for the square stock. This is what baffles me.

[ReMark]

The square stock was rotated too?

 

What error did you get with the cylinder? Do you remember the wording of it?

 

I'm still left wondering why my example works but your doesn't. Can you post the drawing so we can play with it?

[Frana]

It doesn't actually give an error per se. Just doesn't recognize that there is an object to pull against the cylinder?

Yep, I got it to work.

 

Did you know that you had one drill hole copied on top of the other?

[ReMark]

This is it. The blue cylinder has had the circle for the hole extruded through it as per JDM instructions prior to subtraction. The red cylinder has had the hole press/pulled through it just as I said it could.

 

Note the magenta circle next to the blue cylinder. That's the extra circle you had created. I moved it out of the way.

 

[Frana]

Yeah I forgot that I had the DELOBJ set to 0.

 

So, why is I still can't press/pull through? If the top of the cylinder is drawn from the top view. And the smaller hole is placed on the front, what view are you using right to press/pull through? Also, I see that your circle is not against the face of the cylinder, is this why I can't get it to work? I moved the hole away from the cylinder, much like your drawing, and I still can't get the recognition of a regioned area to press/pull...

[ReMark]

Your circle was a region. I blew that away and substituted a plain circle. I relocated my UCS (which I almost always have turned on) to the center of my new hole and then turned my view using 3DO. Press/pulled my circle through the cylinder and that was it. I assure you I absolutely used the Press/Pull command. No magic, real or imaginary, was used to create the image I posted.

Got it to work!

 

Believe it just comes down to a procedure.

 

Much like when I was learning a function with SigmaNest for common line cutting. In order to Move/AlignRotate parts to the correct spacing a certain understanding had to be established of what was happening with each click. It's like second nature to me know, but at first it baffled me on what was happening.

[ReMark]

Glad you "got it to work". We didn't want you wondering as to what magical skills you might be

lacking that some of us possess!

 

I guess we can say that's one mystery solved anyway.
