Missing features: Trim feature + Hiding Model during sketching

Anonymous — Thu, 21 Apr 2016 13:09:20 GMT

Dear Community,

I recently started working with Inventor 2016.

Before I used to work with Catia V5.

Besides the fact, that I get used to Inventor and meanwhile really like it,

I still miss two specific functions, which I hope are not CATIA-only.

(I searched for this functions, but weren't sucessful)

1) Hiding the model during sketching:

First of all, it is of course very useful and necessary to use model geometry for the sketch.

But Is there the possibiliy to hide the model during sketching, so no geometry can be touched unintended?

2) I like to use Boolean Operations, using the function "Combine", like adding, subtracting or intersection.

In Catia there was additionally the possibiliy to "Trim", which is roughly spoken adding specific parts of a second solid to the first one.

This video explains it better: https://www.youtube.com/watch?v=2LmdWXgsGNE

Is a similar function available in Inventor?

Btw: I hope it is ok to put two topics in one Message, otherwise please let me know.

Thanks a lot in advance,

Michael

I suspect this question arose because you have Autoproject Geometry turned on and you are therefore getting geometry automatically projected into the sketch that you do not intend.

Go to Tools>Application Options>Sketch tab and turn off Autoproject Geometry. I never use that.

Looks like interesting functionality, but I don't recall ever wishing I could do something like that (maybe I just never considered it because the functionality doesn't exist in Inventor).

But I am guessing there might be a more appropriate technique for Inventor.

Can you attach your file here?

Thanks a lot for your quick reply. I am very satisfied with your answer on Topic 1.

About this remaining topic:

I unfortunately don't have a part right now, where the "Trim function" is completely indispensable.

But maybe we can just stick to another video here:

https://www.youtube.com/watch?v=qJKpBHkL_ms

For me, a way I would solve it in Inventor could be:

- create a inner surface of the bowl

- cut the screw bosses with that surface

- add with combine

This would solve the problem sufficiently, but the above mentioned "Trim function" would have the advantage, that only one command is necessary to add the desired part of the screw domes to the bowl (using "keep surface / remove surface")

Further the command is independed from the inner surface of the bowl, which I would have used in Inventor

Is there a better way to solve the video example in inventor than with a cutting surface?

Oh man that looked like a lot of extra work.

I would simply use the Boss tool and the Rib tool in Inventor.

Hi mischahtwg2,

Welcome to the fourm.

Does this video help clarify anything? I'm not certian the trim is needed when creating bosses, but I might have missed the point.

Both of you are right,

the tool for creating bosses is a powerful tool (that I havn't knew), which is most likely the best solution for the screw dome topic.

Thanks to you both!

But let me do one more attempt, support by another video example:

(I hope you can bear one more CATIA-Youtube-Video)

https://www.youtube.com/watch?v=o3C_simxJdc (skip to minute 26:00)

Let's say a screw dome is quite simple conic geometry and can be achieved by I a own function, tailored for this purpose.

But please imagine that you have a complex geometry trimmed into another complex geometry, like in the video in minute 26:00

Further, the rib can be even more complex than in the video and trimmed into another complex bowl or something similar.

I think you get my point.

How would you solve that example in Inventor?

Besides, I hope Autodesk can add this feature (hopefully not patented by CATIA-developers).

Man, that Catia video was painful just to watch. I can't even imagine having to model like that.

I was going to say exactly the same thing - felt like I was transported back into the last century.

To be fair, there are alot of Youtube videos that make Inventor look painful too.
