3d scetch whoes

Hello All,

I've been rather frustrated with the innabilities of 3d-scetches. They
are pretty handy in ceratin situation, but they seem to lack some
basic functinallity. Specifically, the select midpoint option, mirror,
and circles/arcs . There are workarounds for all of these, but it
doesn't seem like it would too much to ask to have these features
directly. Anyways, it seems like somewhat of a waste to have a
3d-sketch ability without some (what seems like to me anyways) fairly
basic features.

It also seems that sw2005 is rather unstable when it comes to 3d
scetches. I have had about 6 crashes today, all while creating
3d-scetchtes.

Anyways, just my rant for the day.

-sw2005,sp0

 

I agree.

How about, equal relationships, planarity relationships (similar to
collinear in 2D), angular dimensions between elements with the planarity
relation, standalone circles, arcs, ellipses, etc.

As it is, 3D elements in SW seem to be stuck on requiring some sort of local
cartesian coordinate system based on the last planar element.

 

Definitely rant-worthy.

I especially hate the lack of midpoint constraint. How do you do it?
I end up constructing a "truss" of lines and using parallel constraints
to create similar triangles that find the midpoint of a 3D sketch line.

Symmetry would be tough, as it would require a plane definition.
Perhaps 3D sketch could actually add a sketch-specific plane or CSYS
entity (UG has something like this).

Lack of plane definition is probably what prevents them from
implementing 3D sketch arcs and planes. Sometimes I can get by making
fillets.

 

Yep, similar to the other wants, I've requested more support for
3DSketch and hopefully others will as well.
Definite needs for more functionality here!
And, yep, SW2005sp0 is unstable with 3DSketches!

It's funny, the earlier beta's and prerelease's were more stable than
sp0.0!?

I dont think its '05... I crash that much on 3d sketches in 04 as well :/

But the PARALLEL constraint gives much more power than in 2D ....
