Hiding cosmetic threads

Hello

I'm fairly new to using SW (I'm working with SW 2007 SP3) and I'm having a
couple of problems with holes:

1) Can anyone point me towards a good step-by-step tutorial on using the
Hole Wizard? I've been having a lot of problems with it - in particular,
when pre-selecting a plane to create a hole, it automatically creates a hole
near the location where I clicked to select that plane as soon as I open the
wizard. Moving that hole can sometimes be problematic.
2) When I generate cosmetic threads (either with the Wizard or with Insert
Annotations) the hole is surrounded by a circle indicating the major
diameter. However this circle is visible from _everywhere_ - you can see it
through the part (when the hole itself is invisible) and even in an assembly
when the entire part is inside something else! Is there any way to get rid
of it (leaving only the shaded threads displayed)?
3) There have been several instances where I created a hole in the side of a
cylindrical face. However, when I try to place a center mark for that hole
in a drawing, the program does not recognize it as a circle. I tried using
Convert Entities on the edge, but though I get a spline, _that_ isn't
recognized as a circle either. Is there some way to do this? (at the moment,
I'm hanging the dimensions off the sketch used to originally create the
holes, but I'd prefer a proper center mark - partly because using the sketch
means it's the point is visible in all views, not just the on I'm currently
annotating)

Thx

 

Hi Eyal,

1. For hole wizard tutorial, check Advanced Design Techniques in
SolidWorks online tutorial. You can found it under Help>SolidWorks
Tutorials.

2. Click Tools, Options, Document Properties, Annotations Display and
make sure Cosmetic threads check box is not checked. But un-checking
Cosmetic threads will also turn off Shaded cosmetic threads.

3. For you 3rd problem, when you create hole on a cylindrical surface,
the circular edge turn into a spline and SW will not allow you to
place a center point or dimension using that edge. For a work around,
make the sketch show which is created when you make hole. Now place a
center point with respect to that sketch. Hide that sketch and you can
use the new center point for dimensioning.

Is any of that associative?

 

Thanks!

A question:

"3. For you 3rd problem, when you create hole on a cylindrical surface,

When I use the Hole Wizard, it does not seem to generate a sketch of the
circle itself. Instead, it forms two sketches (plus one for the threading,
if any) - one of which is composed of a point which designates the hole
center location, and the second of which is a rectangle (perpendicular to
the plane in which the hole is made) designating the hole depth and radius.
Without a sketch of the complete circle, to what can I hang the center mark?

 

Hi Eyal,

Show either 3D or 2D sketch in the view. Plot a point and add
coincident relation between the point and 3D point or 2D line end. You
may have to use 3D Drawing view to rotate the view for easily adding
the relation. Refer to pics.

Hi Deepak

This would give me a point congruent with the hole center, correct? Ho do I
get from that to a circle?

I found a work-around in the meantime - if you insert a view using Annotated
View, it will generate a centermark automatically.

Thanks,
Eyal

Yea, that is a PITA, but easy way around that one point, just de-select
any tool when your in the sketch mode (locations), and delete that point
