You cannot edit features, sketches, etc in imported models because there aren't any. IGES, STEP and the other application-neutral data-exchange formats don't support this. If you can get a Parasolid file (.x_t, .x_b) from your external company, there is a better chance of their data coming through as intended but there'll still be no feature, sketch, etc data. Only if your external company is using Solidworks can you get to their source data.
The only other method is to use Featureworks. Can't remember whether this is available in Basic Solidworks (I use Premium) but this is the way to edit and/or recognise features that can then be edited. Here's the Featuresworks help link if you need it http://help.solidworks.com/2010/English/solidworks/fworks/legacyhelp/featureworks/fworks/overview_of_featureworks.htm
I thought this might be the case as I can usually modify most files that are sent to me.
I have requested the original solidworks file from the company so I will have to wait and see if that comes through correctly.
I too have solidworks premium, so I'll try the Featureworks method as well and see if i can get something working.
Thanks again for you help.
While you're waiting for your file, try right-clicking on one of the features (hole, fillet & so on) of an imported model. If it's Featureworks-able you'll get the usual 'Edit Feature' symbol (see attached for an example) and SW will try and sort it. This is 'Direct Edit' introduced in 2010 (I think).
I know I am late to the party, but would feature works work on this part?
I've tried editing the feature (as highlighted by Keith), but i get an error box saying "direct edit not possible. Part contains overlapping solids".
Featureworks cannot resolve the issue either.
I have a feeling the original file was an Alias file (or similar) as the majority of the model is surface modelling. I am also unable to thicken or convert to solids without an error box.
I think I will have to wait for the original solidworks file before i can progress.
Ok, I know feature works has it's limitations, but in some cases it
doesn't work bad. Just thought I would throw it out there just in
case it got overlooked.
Josh - how will the original Solidworks file help if it was modelled in Alias or another non-Solidworks way? Am I missing something?
By the way, if you're in Weston and want some local (i.e. non-public-forum) help I'm in Bristol.
I can't speak for Alias, but I know in Pro-E it can be saved out as an actual
Pro-E part file and opened as such in Solidworks directly with all of the features.
Sorry for the confusion.
I requested that they send me a solidworks file of the model, thinking it would speed up the design process. However, as you can see it hasn't really worked!!
I have just received my third version of the model a couple of minutes ago, which has the same problems. I think the easiest solution is to give up on any conversion methods and re-draw the concept from scratch!
I live in Bristol also so if I have any further problems it would be great to run them by you. Thanks
Are you saying that the file originated from SW, and the customer is sending you every export flavor and not the native SW file?
If the files were created in Pro-E you can with very limited success import them directly into SW, but be warned it will not be seamless and alot depends on the complexity of the part.
Featureworks, again is limited at best, depending on the part complexity.
Going back to my original post, I was first sent an igs file, followed by a stp file of the design.
Both of which did not contain any solid bodies or sketch features.
I've since requested a solidworks file which the company promised to send me, however the latest file I received (which they claim to be solidworks), has the same problems as before (but in french). It even states an "Alias Brep model" in the design tree.
It is not a Pro-E file because I have a years experience with Pro E and known how to convert from it.
It is slowly becoming apparent that the company either do not use solidworks or that they have not drawn it up on solidworks yet.
To avoid further delay, I am going to discard their file and begin re-designing on solidworks.
Thanks for your help.
they must have gotten there file from someone else and imported it to their SW and that is why you can only get a dumb solid.
