Some initial comments (new user)

Ok, have used 2d & 3d cads before but new to Fusion.  Some things make sense, some are good, some things I can see reason behind but others totally baffle me as to why anyone would want to work that way.  Have used SpaceClaim for many years, sure it lacks some things, but it only took a day to learn how to use it to be productive.  I am now on day 3 with Fusion and have created nothing of value (to me).

I have watched about 10gig of YouTube videos, searched the help etc now resorted to using the forum because there seems to be no such thing as "online quick help".  I struggle with this program.  It looks good, smells good, seems to work to a fashion but to do anything productive in 15minutes takes about a day by the time you try to figure out how in hell you actually do that.

Points in question: In all the videos and stuff I researched, not one single reference was made to the fact that if you sketch a circle on the orgin or a plane, you cannot move it!  Spent hours trying to figure out why, come to the conclusion you can't.

Spent the last 3hrs trying to find out how rigid body works.  Read all the descriptions and set up rigid bodies but I can pick them up with the move command and move them where I like - not very rigid are they.  SpaceClaim as an example allows you to LOCK a component (body or structure with or without children components) in world origin and there is no way you can move them unless you unLock.  You can still interact with them freely, sketch on them etc but you cannot move the relationship between the items or any items and world zero coordinates.

I must be doing something very wrong here or RIGID is not the command I am looking for?

OK, with respect to the rigid body, I may have solved this.  It is very backward compared to the way I am used to working.  If I create a new drawing and then drag the previous drawing into it, the previous drawing remains rigid as I had hoped.  However this kind of means that I have to create things from the bottom up - in other words, from the detail back to the concept rather than from the concept down to the details.

Have I got this right?

@Anonymous have you gone throught the learn page

In order to lock a component (not body) down you need to "ground" it by right-clicking on it in the browser and selecting "Ground" from the menu selection.

You can rigid group several components and then move that group of components as a group. If you want that rigid group to be stationary, one of the components either have to be grounded, or assembled to another grounded component.

Something essential to understand that is very different from other CAD systems is that Fusion 360 makes a clear distinction between bodies and components. That is explained in the videos here and written here.

This trips up many experienced CAD veterans as well as e.g. Solid Works or Slid Edge do not make that distinction.

Yes and no.  With respect to what you are probably getting at, no - well at least, not enough as you imply.  I have done some but have been using the program as I go.  With respect to other videos and learning stuff then yes, a great many more than my internet bandwidth can afford at the moment, however, the reason for doing that was to assure me that this program could POSSIBLY do that which I do need.  At this stage I do not seem to be able to find any another CAD program that can so I am trying this one out as the videos I have watched indicate it MAY be possible.

In this respect, I have a model which took a couple of days to draw from real life items (SpaceClaim) but took about another 3 days (on and off) to calculate and measure EXACTLY the relationship between two critical components.  These two components must be fixed in space and everything else I build onto or around these is flexible but THAT original relationship must not move regardless of how I may stuff up in the learning of this program.

Thanks TrippyLighting, that is probably the answer I am looking for.  I will check out the links.

I've been using surface bodies, solid bodies and components in SolidWorks (Inventor and Creo too, I've never used SolidEdge though)  for years.

I always thought the distinction was pretty clear?

Hi @Anonymous,

Remember to check out the links that I have sent you on your other post!
Trust me, you will find MUST them VERY helpful and will answer our questions in this post 🙂

Cheers / Ben

Well, to you, yes. But in terms of your knowledge you clearly define the upper end of CAD knowledge.

I worked for 12 years with Solid Works mostly in traditional mechanical machine design, with the CAD system connected to a corporate wide PLM database and in these roles never touched surfacing and multi body designs, with the CAD system connected to a PLM database. Hat stuff is simply not need for that form of machine design.

Based on feedback here on the forum and seeing what troubles other users run into I can see where that comes from.
