Trim Surface
I want to trim this upper portion. Is it possible to use Trim Surface tool?

Re: Trim Surface
yes, but I think Rob's suggestion is much better
EDIT: just downloaded your part and I'm wondering why you want to use trim surface while it can be done by adding a profile and extrude cut it

Re: Trim Surface
Double check you loft2 - some error there
I just did a quick fix - you can play around and make the loft better

Re: Trim Surface
..uhm... the loft profiles don't make sense..they don't properly flow and fail doing a ctrl-q (surprised this solved in the first place?)
,.. imho,.. this needs to be setup better... here is two ways.. redo the end profile and using a boundary..

Re: Trim Surface
3D Sketch is creating a gap with the non-planer surface. Sketching on a plane and by using project tool can’t we eliminate this gap?

Re: Trim Surface
You can use Combine to join the blade and the bottom and yes you get a small D-shaped face at the outer edge. (width ~0,01mm). It shows up in Geometry Analysis as a Sliver face. This face can be removed by the Delete Face tool (Delete and Patch).

Re: Trim Surface
Maha,.. good to see you're paying attention... (this will be fun to explain)
Anyway, I honestly did not have time to "Combine" before I sent last night and now see what you see...
Ok... this is a great example of "almost perfect"... the curves and surfaces do not resolved exactly.. that is.. line/line or surface/surface,.. or as we expect. (ztg or zero thickness error candidate for sure!)
unfortunately/sadly/ (and other not so nice things to say),.. the cresent edge is the result of how SolidWorks or the Parasolid modeler handles or solves these types of sketches (arc/line versus splines)...that is, "ALMOST"... (0.000000101)
as a fix... you can remove that top surface curve in the "3dsketch - end fan" and add the edge of the cylinder.. it should resolve well,..maybe? that is,..I'm guessing your loft will probably fail (so, you'd need to redo it).. because,.. well.. SW Corp has ALWAYS had problems (it gets confused so how?) with replacing sketches in features... and we have become use to paying for half baked software. (well.. that is the real truth)..

I have found a tutorial. Demonstrator is saying that
I haven't found any good tutorials there......

Re: Trim Surface
yeah,.. what he does show is a good way to handle some of this, forcus on the compressor blade shape (very important),.. then merge/cut later. so, cuting back or removing the rounding/surface/edge/split or rounding errors.
And, in general.. the blades placed on hubs would be independent and over extended the hub.. and then merged/cut back to the hub.
btw.. in the next video.. (which I think you followed?)... How to Make an Axial Centrifugal Compressor in SolidWorks |JOKO ENGINEERING| - YouTube
..between times 8:40 and 8:55, he makes a ZTG statement.. interesting.. because I I'm really surprised this loft resolved or did not give him and you more errors?
