A simple question on sketch
A simple question on sketch
(OP)
I am new to Pro/E. I want to model a circular part in Pro/E. To do so, I am revolving tha sketch about an axis.
The c/sectional sketch (a complex one with lots of lines) of the part has dimensions from 1.0 to 4.0 inches.
I open Pro/E 2001, go to feature->create->solid->protrusion & then select the planes & finally reach the sketch mode.
Then I go to the quadrant-1 & start sketching the c/s. Once I draw the final line & close the sketch. I find that the dimensions are in the range of 150, 200, 300 inches.
When I click modify dimensions & click one dim & change it to my actual dim of (lets say) 2.25inch. The full sketch adjusts accordingly & so it deformed the entire sketch & now what is have is a bunch of lines & i am not able to make out anything, Pro/e has adjusted the sketch & i am not able of makeout anything.
My questions is:
1) Since i know that my part is a small part with biggest dim as 3 in & not 200 inch, is there a way that I can set the screen before starting the part or before strating the sketch. SO that even If I draw a line from one corner of the sketcher window to another corner it shows it to be around 1 to 10 in in lenght.
2) I understand that before starting I zoom in & then start I can do the above, but how much to zoom in so that I can have dim's around 1 to 10 in in lenght.
3)Is there anyway to reset the screen to model small size parts
4)How to align parts? I couldnot find align button while using indent manager.

RE: A simple question on sketch
I don't know about the zoom factor for small parts however, if you want to work on a sketch without it turning inside out try the following:
When you are ready to modify the first dimension in your sketch, click on a dimension, when it turns red, right-click on it and select MODIFY.
A modify dialogue box will appear.
Now, left-click on all of the other dimensions that you want to modify. Now uncheck the REGENERATE box and check the LOCK SCALE box.
Now, you should be able to change the values without the sketch imploding. The sketch should regerate once you exit this dialogue box.
Finally, for your fourth question:
If you want to align sketch entities?
There are ALIGN VERTICAL and ALIGN HORIZONTAL features in the CONSTRAINTS dialogue box.
Hope this helps,
JW

If I have any further doubts in future I will post it & will need your help again.
Thanks for you help.

You canmake a default start part, and make the default datums to say 5 units long (use RADIUS), now the sketcher zoom will be larger.
This is a workaround only.
