Lilly Leaf Molding Tutorial

Postby ohiolyons » Thu Jul 27, 2017 6:10 pm

Just refreshing myself with the tutorials because of Version 9. While watching the Lilly Leaf Tutorial I noticed a possible change. In the past I was told that the modeling resolution was fixed at time of creation and could not be changed. In the updated version tutorial they opening an existing file and then change the modeling resolution.

1) Was my understanding of changing the modeling resolution wrong in the first place?

2) Is this a V9 change?

3) Is this a gray area where the file opened didn't have any 3-D elements so you can change the resolution?

4) Does the modeling resolution only become fixed when you create your first 3-D component?

The current v 9 HTML manual under JOB SETUP, MODELING RESOLUTION does not address this. The printed V 8 I have also doesn't address this. I remember a seminar speaker saying model resolution is fixed and can't be changed.

Hi John

Resolution doesn't matter if a file is all vectors (as in the part 1 - Lily Leaf Drawing tutorial)

You are correct that the resolution setting you want must be set before the introduction of any models in a project. Imported models will "inherit" the job resolution settings and any new models that you create will be made at the current job resolution setting.

If you change the resolution to a higher amount after that, there is no benefit because the existing models are already "locked in" to the resolution you had when the models were imported or created.

That's why Beki increased the resolution immediately before creating any models in part 2 of the Lily Leaf tutorial.

She did increase it a second time when she created the four panel molding.

So since the model was created at a lower resolution she didn't gain anything by increasing the resolution before she copied it 3 times?

The model resolution itself did not change from the original.

However, because she increased the Job Size, the benefit to increasing the Job Resolution is to "pack" more pixels into the overall job itself. If she didn't do that, the set of models would be pixelated due to the job pixels being spread out over a larger area. This would result in a poor rendition of the models.

Increasing the overall Job Resolution allows that model to retain its quality within the job, but the resolution of the set of models did not change.

Confused yet? :D

I can confuse you some more! In the new version 9, when you import an external STL model into a job with a high resolution setting, that model will now come in at the high resolution. (Prior to this, an imported STL model did not come in at a high resolution.) Of course, the resulting quality is still dependent upon the triangulation accuracy of the original STL.

Thanks again, either I'm getting better asking the questions or you're one of the best explainers ever!!!
