Origin Point

[FIFTHTEXAS]

I Am Just Starting To Learn Inventor Am A Solidworks User Trying To Transform. Can Someone Tell Me How I Can Lock Line, Drg Etc
On To The Origin Point So My Drg Is Locked To Centre Of Screen
My Drg Moves When Dimensions Are Added I Want To Keep Drg In Position I Am Using Version 10 Have A Book Inventor 11 This Has Asetting In Options "autoproject Origin Create Point" Where Is The Setting On 10

Regards

Dimension the postion rather than the line. Run thru the 'Sketching' section of the help file and mainly look at the 'constraints' section.

I believe that is new for inventor 11. What you can and should do is, expand the origin folder at the top of your model tree, select the "project geometry" tool, select "center point from your origin folder. This will give you a grounded origin point to attach to. You will need to do this for every sketch you start. It sucks but it is what you have to work with. Like I said, this is fixed in IV11.

You are on the right track though. Always fully constrain your sketches. Never use the "fix" constraint under any circumstances. Always constrain to your origin, this will help you later on when you need to create work planes and when constraining in assemblies.

There is an easy way and will stop you from having to do this process of expanding the origin folder and projecting geometry etc every time, and that by setting up a default folder with projected origin inplace this can be done with any version of Inventor

1. Follow Aardvark's process above
2. Save as, then goto program files/IV10/Templates/ and save in there as (you name or what ever you like).ipt
Then when you go FILE>NEW your temple is there, select it and the projected origin is in place for you.
always start your sketch from the origin.

You can also set all the settings for your liking before you save your own template.

Deelay,

The only reason I didn't include that bit ( and I almost did), is that this projects the origin point into the first sketch of every new part (sounds ok so far right?) but this happens when you open derived parts, iPARTS or SAT, STEP, IGES, etc as well. Not horrible, but it can get annoying to have this sketch with a dot in it that you can't remove.

That being said, I agree it works very well and you don't have to repeat all of those steps every time you start a new file. You will still need to do this for every subsequent sketch in that part.

I had an Idea you knew how to to it as by reading your posts I can tell your well clued up with Inventor
