Surface Models - Convert to Solids

I know this topic has been beaten to death.  I frequent these boards a lot and constantly see these threads pop up.  I read them all and try to follow any guidance, links, tutorials, etc... But I still can not grasp how to convert them.  My Inventor knowledge is minimal (been using it for approx 5 months and have attended a Basic Modelling course by iMaginit) A customer sent us 9 different parts (very simple and basic).  All of them are surfaces.  For the first few I just modeled them and carried on.  But it has me thinking that this would be a perfect time to learn how to turn them into solids without having to model them from scratch.  Again these parts are very simple and if worse comes to worse, I will just model the remaining parts. Can anyone provide simple instructions (looking at you JD! :smileyvery-happy:) or guidelines or a walkthrough that I can use in order to attempt at turning these surfaces into a solid.


Attached is one of the models received for your viewing and investigating pleasure.

 

I am using IV 2012 Pro and have SP1 installed.

What format did the customer send that to you in?

Are you the one that created an assembly of all those surfaces or was it originally one neutral format file?

 

If for some reason you are getting Inventor files like that (rather than neutral format)

1. Start new part file

2. Exit sketch

3. Manage>Derive Component as Composite Surface

4. Copy to Construction (22010-2012)

5. Double click on Construction

6. Stitch the surface to solid

7.Copy object to the modeling environment.

 

But I suspect there is an easier way if your geometry came in a single file.

I am not sure what the original part was modeled in.  When I received these files, they were in STP format and that is exactly how I receive them (numerous Surafaces in an Assembly environment).  I will investigate the steps you listed and report back.  I will also look into the Options when opening up the STP file before saving as an Inventor file (.iam).

STEP File Options.jpg

 

These are the options available when first opening the STEP file......


I changed the following options...

 

Create Surfaces As....Single Composite Feature

Import Assembly as Single Part --> Checked

 

The resulting part is as follows....

If you read my document on neutral format files - need the actual STEP file to find the best set of options.

Zip and attach the step.

That is what I thought - this is a lot easier that the Inventor assembly you posted first.

Here are the options I used

 

There is an extra surface besides the solid that I think you can delete (I didn't look close).  I think it represented thread in the chamfered hole.

 

I turned off the Translation Report only because it causes a problem on some systems (the file won't open at all - so it is not a problem on your machine).

The step file you attached doesn't seem to be right. It just contains a single cylindrical surface.

 

You may want to check out Fusion 2013 (which is freely available, even if you are on an older Inventor version) as a simpler alternative to handle less complicated imported models.

Are you saying STEP import is broken in Inventor 2013 (not Fusion).

(Opened fine for me in 2012.)
