Exporting Files Problems...

Exporting Files Problems...

Exporting Files Problems...

(OP)
Hi.

 I have modelled a complex radial molding using combinations of swept surfaces, fillets, variable fillets and sweeps which I managed to stitch and thicken into a solid from the knitted entities.

 When I detail the drawing in the .idw it comes out okay, but I cannot dimension the part properly, also, the customer will need a 3d model and a 2d Autocad dwg of the part to manufacture the mold tool to.

 If it was modelled in Mechanical Desktop and views generated from that model, when exporting the Drawing Views it allows you to 'flatten all entities and convert splines to arcs and circles', which greatly helps the downstream people as they can use real radius's and not obscure splines. Unfortunately (for some bizzare reason) Inventor 9 doesnt have that option.

 What I thought I may do instead was use the DX link to the IV part and create views in MechDeskTop and then export those files....this gives a terrible quality drawing (yes I have checked viewres and facetres etc), and actually starts to rather oddly and un evenly create jagged or octagonal looking curves - no use what so ever its that bad - infact some lines were totally disjointed from each other even when viewres was set upto 15,000.

 So, next thing was to try and export STEP, IGES and SAT models from inventor - the customer will need this to manufacture from!......however, Inventor isnt producing quality files of the model....if you import it into other systems (even MDT) the model is not perfectly smooth faced - its not far off - it looks like the part, but it doesnt seem 'right' and smooth curvature around blends and fillets (a bit "blocky" if you like in areas).  My graphics card is 128DDR RAM and Im quite sure its not a card problem anyway. Some bits are okay, others are not.

 So, Im a bit stuck as to what to try next.  I tried modelling a 3d path curve of a circular shape, and upon DX linking that as a test, the result was the same!....it cant be the IV model because thats as smooth as a baby's bum in Inventor itself. lol.

 Does anyone know of this happening?, is it a known issue with Inventor?.  Its taken a great deal of modelling and thinking about so far, stretching my knowledge of the construction and usage of the program quite considerably...litteraly on the egde!, there may be tweaks to do on the shape before production and Id hate to have to loose such parametricity of the model and try and reconstruct things from scratch more difficulty and unalterably in Rhinocerous or MDT.


 Thanks for any idea's,

Sirius2
