Help in Making Helix Gear

[basty]

Can someone tell me please how do I make a helix gear in AutoCAD 2014 in classic workspace?

 

Is it using Loft command or Sweep command?

 

How do I use Loft command using a path?

[basty]

Please see the attached .dwg file.

The red line is the path.

Gear.dwg

[ReMark]

You can loft the two profiles to achieve the desired result.  You don't need a path to do it either.

Why my AutoCAD 2014 doesn't work when trying to use Region command? please see attached file

Region.dwg

The triangular portions of your drawing are actually a block reference.  You can't make a region out of a block.

What is block reference? Fyi, I created the 2D triangle and make Region on it.

The triangles are all part of a block (a group of objects treated as a single entity).  You cannot use a block to create a region.  Explode the block then try again.

[basty]

I use Explode command as you instructed and next, I make a Region of it.

But I doesn't want to be extruded.

The command message is:

 

"Cannot sweep or extrude an object of this type."

You're going to have to explode the triangles a second time because, for some unknown reason, you created individual triangles as a block then grouped them together to create a second block.  Your understanding of creating blocks needs some refinement.

Sorry, I followed your instruction but still doesn't works

However, I manage to make it work.

The step is, I make Region of the gear teeth (this case is triangle), then Extrude it, and next it to Polar Array 10 items.

The image below demonstrates what lies at the root of your problem.  On the far left is your original objects.  I copied the triangles to the right.  They represent one object.  I copied the triangles to the right, again, and exploded them.  Now you have ten objects.  I copied them to the right, one more time, exploded them and now you have thirty objects.

 

 

What do you mean with 10 objects nd 30 objects? How do I check it?

[ReMark]

It didn't work because you created an individual tooth of the gear as a block.  Then you grouped ten of them together and created a second block.

See above post for answer.  I checked by using the Erase command and selected the triangles.  If you look at your command line it tells you how many objects have been selected.

Here is a better image... Layer colors are white, yellow, green and cyan.

How it can be? I am not using any commands related to block and group.

[ReMark]

Maybe it's your repeated use of the Region command?  I don't know.  I no longer run AutoCAD so I cannot test it.  I did prove that whatever method you used it negatively affected your ability to create a region out of the gear profile that you posted.

[basty]

Why too many wireframe on this Lofted gear tooth?

 

 

[ReMark]

Could it be that the tooth is comprised of multiple, separate lines?  It looks like someone created a solid then exploded it thus creating surfaces.

I don't know. I just make the gear tooth profile (in this case is a regular triangle) in 2D and make a Region of it and then I copy and arrange the triangle to the desired position and I Loft it.
