Adaptivity not working

Anonymous · ‎06-03-2003

Could someone please have a look at the assembly (frameadapt.zip) in INVCF.
I am trying to make the part testflat adapt in length automatically when the
length of the part upper_rhs is changed.
At the moment I get an error message when I change the paramater for length
in the upper_rhs part. However, when I go back to the assembly, as soon as I
move the part that is apparantly in conflict it jumps to the position that
it should be and all errors go away.
I know that there are ways around this, but thought that this was a fairly
simple use of adaptivity and would like to know if I have somehow
created/constrained this wrong.
Thanks in advance for any thoughts,
Dave Moore.

Should have also mentioned using INV6 SP2. WinXP Pro.

Scrap the workplane on "Test Flat1"
Edit the part enter the sketch and project the origin centre point to
sketch, and constrain midpoint on sketch shortest side to the new projected
point.
Now your part remains centre about the origin workplane.
Although centring parts round origin it is said is not strictly necessary it
makes good practice and you can always opt for not using the origin plane,
but its good to have it there in centre of part.
Finish edit and delete the redundant constraint " ! "
Reconstrain part with origin workplane.

Because the sketch and extrusion were adaptive the workplane you constructed
off extrusion sides will try to gum up / confuse for want of a better word,
the solution to the new length.

Thanks Laurence,
I had a feeling that it was something like that, just couldn't quite figure
it out. Looks like we'll have to be a bit more stringent on our modelling
methods!!
