processing of an unsuccessful part - neophyte

[Stemox]

Good morning.
after different time I wanted to resume with creo, I admit that I do not remember how much done and to refresh I am practicing with the videos that I find on youtube.
the operations on the parts are very simple but I have some problem the cad does not run me some phases and I do not understand why. the exercise at some point previews the extrusion of a text, I follow the various commands but in the end I have an error message ...
I attach some imgs of phases...you know why?

Hi.
the height of the text is very small. try to increase it, or change the precision of the model.

 

[Stemox]

I have to exaggerate a lot to make my extrusion. how do you change the precision of the model?

 

[DANI-3D]

with wf5: file > properties model > accuracy, proof with absolute 0.001

 

[Stemox]

very kind thank you, now it acts!

another question, in creating a text on a bow I'm told that "the sketch text produces degenerative signs"
Where's my mistake?

 

[Stemox]

I make a higher text but it creates it so I go out of the flat surface ... why the smaller does not create it?

- I answer myself... increased the precision of the model, the operation is performed.
But I do not understand why it does not realize it even if accuracy is 0.01 ...the values set are however higher.

For me precision is a strange thing, and when there are little logical behaviors of the cad, often varying it they solve.

What precision did you set?

 

[Stemox]

from 0.01 initial are passed to 0.001

I recommend putting 0.0012, is a value that works in 99% of cases.
