Talk:Blender 3D: Noob to Pro/Creating a Simple Hat

=What?=

Make it look like the picture on the right my foot. How am I supposed to do that? That section needs a lot more detail.

=KDE problem=

'''(CTRL+TAB) switches desktops in Linux KDE. Need detailed instructions on how to switch between modes without using that key combination.'''


 * I run KDE at home and do not recall having this problem. I will look into it.  You can switch modes by following the instructions on this page:  http://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro/Detailing_Your_Simple_Person_2

=Purpose of Extruding the front edges in Final Touches= I don't understand the purpose of extruding the 4 front edges of the hat. What is being accomplished? Does it have anything to do with the split seams from the doubled vertices?

 * You're creating a brim for the hat. A brim?  A rim?  What's it called?  Anyways, whatever you call the thing on the hat that's supposed to keep the sun out of your eyes.  --Spiderworm 22:01, 22 Apr 2005 (UTC)


 * According to my dictionary it is called a 'peak'. --Pinzo 22:17, 9 July 2005 (UTC)

Smoothing the hat
If I set the smooth to the hat it looks awful, with 12 dark lines following the edges. Does anybody know why is this? How can I get it right?--Pinzo 22:20, 9 July 2005 (UTC)

Ok, I got it. It happened that the 'spin' had the normals turned with each slice. Flipped them manually, and that's nice. Can this be avoided when spinning the hat? --Pinzo 23:17, 9 July 2005 (UTC)


 * Next time you have that problem, in Edit Mode, select all vertices and press CTRL+NKEY. It will prompt you if want to flip normals outside.  Choose yes.  --Spiderworm 00:08, 10 July 2005 (UTC)

Adding new vertices
I do not understand the needs of adding new vertices in section Creating the hat profile. After deleting three edges from the circle, it remains 9 edges, and from the image shown there are also 9 edges to build the hat.

Did I miss something or GKEY combined with RMB and AKEY are sufficient to do the job?

--Miga 10:25, 18 September 2005 (UTC)

Your not adding new vertices, more like rearranging the vertices. I really want to know whats with this... -make sure you're in Object Mode (TAB) to add the hat as a separate object. (Note: It will cause problems if you do not switch into Object Mode)-. In Object Mode my circle is made on the Z axis when it should be made on the x or y axis so I can spin the profile vertices on the z axis. I stayed in Edit Mode and had better luck with this whole hat making ordeal. And yes I'm using version 2.48

Final touches
Can this sentence be made clearer? I con't understand the last part.

You need to be in top view during extrusion so that the cap bill comes forward and not down,if it was made from the top view

= Keyboard Shortcut Mismatches result = While editting the hat, it says "Switch to Edge select mode (CTRL+TAB)". At this point, CNTL+TAB is toggling between object mode and weight painting mode, a mode I had never touched before. I'm running Mac OS X 10.4.7 with Blender 2.4.2(a?).

When in object mode, CTRL+TAB switches from object mode to weight painting mode. If you are in edit mode, it allows you to choose between edge, vertex or face select mode. So the problem i you were in object mode instead of edit mode.

HELP!
I can't find the screw option in mesh tools!
 * It's to the right of Spin and Spin Dup. For this tutorial, though, you will want Spin, not Screw.—97.95.42.33 (talk) 20:46, 15 January 2009 (UTC)

Invisible mesh
When I go to add a circle mesh, it goes into edit mode but I can't see anything. If I try to select something with a right click it flares up yellow and then goes again, leaving me with still no edges or vertices visible. So I can't make my hat! What have I done wrong?

--81.159.183.85 14:13, 12 April 2007 (UTC)

Oh Noes!
Sombody previously wrote here: I can't find mesh tools at all!

I had this same problem, and found this page this when I went searching for a solution (so I am now updating the solution, since I couldn't find it explicitly answered anywhere else...had to hunt around to find it on the Manual/Meshes page). The tutorials just says to hit f9 to get into edit mode, but it turns out that it may put you in either edit mode or in object mode when you hit f9. If you then hit the TAB key, it will toggle between these modes. In the object mode, you get the "Mesh" panel, and in the edit mode you get the "Mesh Tools" panel, which just makes you think you actually got into edit mode. Hope this helps

hat is flat
this feels like sending a message in a bottle, but here goes:

i've gone through this lesson twice now, and i still have the same problem: the hat when finished is flat as a pancake. i've looked at it from every angle, and yes it's flat. so really, it's not a hat at all -- just a flat round thing. i've paid very close attention to every detail in the instructions, and i'm sure i've done everything as instructed, but the hat has no height (or depth, of course). please help. i'm using blender 2.48.

Flat hat
Your hat is flat because you spin the curve around the wrong axis. If you choose top view it spins around th z-axis and create a pancake.Don't push NUM7 when done with the selection, push NUM1.

thank you. that works. but shouldn't someone change the instructions -- or did i misread them?

You didn't misread them... I've gone through the tutorial with the same results. I've made the necessary changes in the tutorial to include the proper views and axis information. I am not sure if the original author rotated the original circle before editing, or if it was just one of those unavoidable situations where each version of Blender does things differently. My update proceeds from the assumption that the face of the initial circle is visible in the view that the original author specified, that the other two views show only the edge, and that the original rotational orientation of the circular mesh was unchanged. It's a kludge but it will work for now, until someone with a different version of blender can address whatever differences there are.

- Update: I ran through this section of the tutorial step by step and made changes in all the references that were inconsistent, and added some more context to the troubleshooting section to take out most of the guesswork and ambiguity.

- Retraction of previous Update: After making the changes to allow the tutorial to work with Blender 2.48a, I realized it was now broken for version 2.43 and older. I reverted everything back and found a true fix for the situation, and updated the tutorial accordingly.

BIG UPDATE: == == After much work with many tutorials, I have found that nearly every difficulty such as these can be resolved by simply setting the  (i): USER PREFERENCES menu in the right way. Newer versions of Blender (such as version 2.48) can be made compatible with older tutorials by changing some important settings:

1) Find the "User preferences" window 2) Select the [EDIT METHODS] tab 3) Under the header "Add new objects", click the "Aligned to View" button. 4) Optional: For some tutorials it may also be helpful to click on the "Switch to Edit Mode" button.

Making these simple changes will "unbreak" tutorials written under Blender version 2.43, because when these older tutorials were written, new objects would automatically be oriented to whatever viewscreen orientation is being used. Version 2.48 is set to use the global axis orientations by default, which is why object orientations are so often not aligned right when following older tutorials literally... there was no way of knowing a future version of Blender would be set up to ignore when you changed from top to front to side view. Any time object rotations end up completely out of step with the older tutorials, these steps are your first best workaround.

Spins in a curvy way in 2D (wrong axis)
When I clicked Spin after following the page's instructions exactly, I got this. Why?—97.95.42.33 (talk) 02:33, 9 January 2009 (UTC)

Hat has a weird look...
Once I extruded the hat's front and followed the instructions exactly, I got this. I extruded it just as far as the picture for that showed. And it also has these weird...things outside the pink area.—97.95.42.33 (talk) 20:42, 15 January 2009 (UTC)

There is no circle!
I did Space->Add->Mesh->Circle and gave the properties according to the tutorial and hit Ok, but no circle appears anywhere. I see the name of the Circle at the bottom-right corner of the view. What gives?

Questioning use of the word "genatrix"
In the sentence, "You could use any sort of mesh object here because you're about to reshape it into a custom 2D mesh (called a genatrix) that describes ..." the word "genatrix" does not conform to the spelling of apparently the same word elsewhere in the section. Is it "genatrix" or "generatrix?" Or does "genatrix" mean something different?Mtjlt (talk) 11:57, 16 November 2010 (UTC)
 * According to my Random House dictionary, the word is "generatrix". Sorry for the confusion. --Stepheng3 (talk) 01:01, 17 November 2010 (UTC)

Practical Joke?
I believe this section of the book contains what is either an error or a practical joke.

Unless I have misread something several times, the instructions for creating a hat on this page begin by telling you to create a circle, select all the vertices in the circle and then erase them. If you do this, it means that you have created an editable object and then erased it completely leaving you with a blank page. It makes no sense.

unexpected spinning result
Hi

So after completing the hat tutorial i found a difficulty once you have "spun" the hat.

I would like some clarification. Does the hat spin around the 3d cursor? So basically the center of the hat will be where the 3d cursor is.

If so you should stipulate it in the tutorial as i got a hat that look more like a vase :P

Blender 2.61: Ctrl+LMB doesn't create vertices.
I haven't messed with the hotkey settings, and under User preferences, Add new Vertex is, in fact, defined to be ctrl+LMB - but doing so in vertex edit mode doesn't add a vertex.

Is there some weird setting that's messed up?

Create a mesh circle at the cursor, why?
After creating the mesh circle the instructions go on to the following:

The newly-created mesh should be selected. If it isn't, select it by clicking RMB  on it. Press Tab  to edit the mesh. Activate Vertex select mode. Press A  until all vertices are selected. Press X  to erase all vertices.

The adding and removal of the circle mesh seems to be an unnecessary step, which seems to have no purpose. Is the circle mesh needed ?, if not why is it added and then removed ?. This part of the tutorial is confusing and unclear. Collectionneur (discuss • contribs) 02:30, 18 December 2013 (UTC)


 * That confused me too. Maybe the steps are out of order, and you're supposed to delete the circle after creating the generatrix? I'll check the history to see if I can make sense of this... Serpinium (discuss • contribs) 10:39, 21 April 2014 (UTC)

UPDATE: I get it! You have to create a mesh in order to go into edit mode! I'll put that on the page to clear things up... Serpinium (discuss • contribs) 10:50, 21 April 2014 (UTC)
