very good, we'll keep you on a while longer ;o)

3 questions-

A.can you be explicit where you place a control point on the UV's for
the triad as you picked a place to pull the crease? i.e can it be at
25% along a curve or perhaps 5mm from an edge or is it only visual..
Obviously I haven't played with this but it still looks like you might
get something a bit in determinant/wavy/billowing unless you kept the
number of points and your splines/reference geometry simple
( I think I had some concern about this last release with the boat
demo)

B.is the curvature comb auto smoothing still in development?

C.will there be a tube tunnel included in the new realview lighting?

I'm watching it now. It's long, long overdue!

Suggest you make more. Lots more.

 

Mark,

Nicely done stuff! It is useful for me to see how other people work.

I have to admit I got burned badly in 2005 using internal spline handles
where a handle would flip position occasionally, changing about 30
degrees. A customer got hold of the SW file and didn't even look at the
part before saving it as an STL. Everything still rebuilt fine, but
there was a big bulge on the side of a $3000 rapid prototype. Needless
to say, I'm still a little gunshy with internal spline handles.

That razor is a popular part, I used it 4 years ago for some training
material I developed. www.dezignstuff.com/images/razor2.jpg

An earlier version razor I borrowed from Paul Adams back in 97 or 98 was
done completely in solids. www.dezignstuff.com/images/razor1.jpg

The new tools really are very slick, and now the dilemma is often "which
tool that does the job do I pick" instead of "how do I work around this
shape with tools that don't really do it".

Thanks again for sharing this.

 

Nice tut's, Mark!

My only suggestion is with the color/specularity of the surface used,
dark gray, with the curves, it was difficult to see what you are
talking about.
A lighter color with specularity would have made it easier to see,
imho.

Oh,.. using split part,... I still think that is one of the most
dangerous features for sharing bodies you guys have created!

...

 

also...now the realview stuff is here..
what about the ABC/123 grid overlay for the 3d window, and the making
use of the Rx recording feature, that was suggested a while ago
both of these would seem trivial progamming but very useful
cant you squeeze em in?
(also it gives the new eye candy enhancements some obvious worth if
you are a graphics sceptic)
- you guys always seem to miss doing just that little bit more that
makes it great rather than ok and wait till next release... (

 

You can place the control point at any point along the control curve,
but
we don't have the provision for specifying it dimensionally. You can,
however,
snap to external SW sketch geometry. Also there are the Thumbwheel and
numerical controls in the PM for the control points along the curve.
Currently you
can not "slide" the control point along the curve, but rather it
become a, if you will, a
spline point on the curve. This is something we're looking into. The
work around
is to create a new point next to the existing and then delete the old
point.

Yes, in general for NURBS, simpler almost always equates to a more
fair face or surface. In otherwords, the more curves (internal) that
define your surface the more constrains that are evaluated by the
surface and, in most cases, introduces more ripples and less fairness
to the surface overall.

Not quite sure what you are referring to here? Are you referring to
the show curvature display or the actual smoothness of the spline
curve? We put back in the outer curve of our show curvature (in system
options) in SP2 of 2007 (after it was remove in SP0) We did this
initially because there is an inflection problem in the combs that
conflicts with the outer comb after we had complaints. We are hoping
to improve our show curvature but nothing in the immediate future. On
2D and 3D sketch splines we have made an improvement on them that when
you pull asymmetrically on the interim spline point that we don't
break tangency (like in 2007) but keep it C2. Also in 2008, we took
care of some annoying underlying problems with trimmed surface edges
not maintaining curvature at the end points as well as converted
geometry from those edges.

We don't have a tube tunnel but we do have a Light Strip RV scene
(like the auto industry uses) in 2008 which is useful for evaluating
surfaces.

Paul, I agree and have highlighted this in my SWW presentations as
well as others, but....

We have finally re-written Split part for 2008 so that it is now "much
less dangerous" in that you can now redefine the stock feature (master
part) and pick a different body solution. You can additionally pick an
entirely different master part file. This also applies for "Save
Bodies". I would encourage you to take a look at 2008 Split part -
while we still are in Beta/PR

Yeah, this is true for me too, especially in the role I have now. This
video certainly shouldn't be taken
as "the way" you do it, just one of the many ways you can do it.

Matt, what about fully defining the splines before you release the
part?
Abet, now that I think of it, back in SW05 I don't think you could
fully define
a spline - you can now.

That's funny, I didn't realize that it was done before. If I knew, I
would have just come
to you first... or gone up stairs and talked to Paul

Good point, and one of that we need to do a better job on in our
Docs. I'm thinking of something similar to the PP presentation that I
gave that shows a comparitive between Loft, Sweep, Fill, Boundary and
Freeform and the uses for each. Do you have something comparable in
your Bible?

 

Yeah, Matt showed us this way back in 2002..

Kewl, that re-write to add options to redefine the body is very
important!
I've seen some of my clients using split part and it just freaks me
out!

I've also made these videos downloadable at the following SW page:

look to the right-hand column "3 Part Consumer Product Modeling Demo"

"This video certainly shouldn't be taken as "the way" you do it, just
one of the many ways you can do it."

If you're really interested in showing other ways than you need to
make more videos showing alternative methods.

"I'm thinking of something similar to the PP presentation that I gave
that shows a comparitive between Loft, Sweep, Fill, Boundary and
Freeform and the uses for each."

A very good idea! Why not apply the concept to a real world model and
make the video interesting like you did for the razor. Without a
practical real world example like the razor I find myself losing
interest quickly.

"Do you have something comparable in your Bible?"

ROTFLMFAO.

**** no! There is only one surfacing chapter in the SolidWorks Bible
and it's very, very basic. See Matts blog for others that want more on
surfacing and their frustrations.

When I finish the SolidWork Bible (I'm about 300 pages into it) I will
be posting an extensive list of all the work that the SolidWorks Bible
really needs. Some of my comments already appear on Matts blog but he
censors quite a bit of them out.

The SolidWorks Bible is a great resource because there is a massive
vacuum on documenting SolidWorks. This does not mean that the
SolidWorks Bible doesn't need a lot of work... it needs a ton of work!
Even so, I'm very glad I purchased it. Same with the SolidProfessor
videos which are also not complete enough.

The SolidWorks Bible is very helpful but it's far from the standard it
could be / should be. Beats fucking nothing though and that's about
what you get with SolidWorks 2007.

No, the chapter on surfacing just covers the basics. In order to do
the topic justice I would have needed a couple hundred pages and
another month, neither of which I had. So I just went through a couple
of examples and left it at that.

One thing I'm still looking for is some sort of a guide that shows
exactly what all of those alignment options do in the boundary
surface. Something that would give me the ability to pick one by using
some method other than trying them all to see what they do. They might
as well be called A, B, C.


Wow, Paul S - your memory is frightening. How do you remember stuff
like that from so long ago?

 

Mark,

I remembered in the video that when creating the Freeform surface, you
aligned the triad to a selected plane, but I didn't remember
immediately how you did it. Later I went back and tried to do it
myself. The function is not listed in the help, at least I couldn't
find it there. It turns out to be on the RMB menu when you click on
some part of the triad, which is a nifty little place to hide things.
I assume that the Align To... and Align To Selection... options are
really just the same things, just depending on what part of the triad
is selected. It's a little confusing because the RMB Align To option
overrides the Triad Orientation setting in the PropertyManager. Maybe
it would be clearer if all of the triad alignment tools were in one
place and obvious?

Another option like that that's hidden in the RMB and not documented
in the Help is the "flip relation" option on a spline tangency, used
when a spline goes tangent 180 degrees from the desired direction. The
option is only available, as far as I can tell, by right clicking on
the Tangent relation shown in the Existing Relations box when the
spline is selected. You have to right click on the Tangent1 text. As
you all say "that's not very discoverable".

 

Whoa! How long has that been available? Knowing that was there could have
saved me countless hours of rebuilding sketches where the tangent splines
flipped on their own after a change to the model.

well its there in SW05 ;o)
I think I have seen this written down somewhere but I cant remember
where

 

Matt, the following is right out of our help file by searching on
Triad Move

__________________________________________________________

Selections
To move the triad to a selection:

Right-click on the triad (anywhere except on the rotation rings) and
choose Move to Selection.

Select an entity.

To align the center ball with a selection:

Right-click the center ball and select Align to.

Select an entity.

You can also align the center ball with a component origin or the
assembly origin.

To align an arm or wing with a selection:

Right-click an arm or wing and choose Align with Selection.

Select an entity.

___________________________________________________________

on the "flip relationship", I couldn't agree with you more. And we
need to do something about it.

Regards

Mark
