snap, select not working within sketch

[Anonymous]

Hi there,

any help would be greatly appreciated. I am new to fusion and am having some very odd things happen within fusion. At the moment I am trying to do Lars Christensen's 1st lessons and am "sometimes" unable to select faces, points or lines. For instance I have just restarted the lesson and have drawn a rectangle and extruded it. Next I am trying to use the offset tool to put a second rectangle inside a face of the extrusion but nothing is selectable. I have done this previously but am now unable. Any ideas??

If i try to draw another rectangle I am unable to snap to anything but if i draw a line I can snap to points, I am very confused. Is this a bug or what.?

Check the Select > Selection Filter

when the Menu is expanded, ticks should exist for all the articles you want to select.

By default all are normally ticked.  Right through Fusion, menus are edited to gray out or remove menu items that your current operation doesn’t use, might be something on those lines, 

if not something there, we will need a screencast to see what you do - Fusion doesn’t do.

Might help....

another thing to check - how many sketches do you have in your design?  Fusion will only select geometry from the active sketch while you are in sketch mode.  If somehow you created a second or third sketch, geometry in those sketches will not be selectable.

Thanks for all your help,

What I have found is all the selection filters are on and as suggested I have to edit the sketch with the original circle in it to have a new circle snap to its centre. 

Although, since I am only learning and following tuts step by step, it is evident that the programming/philosophy/default options must have changed since Lars did his 2016 tut videos. In the tut (link below) i have been following, he clearly right clicks on the face of a previously extruded circle and creates a new sketch which still allows him to snap to the centre. You can see him creating the new sketch and snapping it in the following video at approx 2:49 min (https://www.youtube.com/watch?v=HXRMzJWo0-Q).

This does not happen on either my mac or pc version of fusion, so I dare say this function has been removed, or he uses some other options in his preferences. 

I hope that all makes sense. Thanks again, It was driving me mad.

**edit** I am not convinced now I have just tried to redo Lars tut from the beginning and I am able to create a new sketch and snap to parts of the first sketch I made, with a circle, rectangle but I cannot select the rectangle as to offset, as per Lars' first tut (https://www.youtube.com/watch?v=HXRMzJWo0-Q). I did manage this the very first time I did the tut. I do not understand how, but I definitely did make the offset the first time. But regardless, I do not have to be editing the original sketch to snap to a component in it, and the sketch can even be invisible. 

So why can I no longer do an offset?? Any ideas?

Fusion must be changing something, surely.

His preferences, when creating the sketch it can project the face of the body. 

these days there are no purple outlines but there is an orange shaded profile, one clue, 

Now that article is in the current sketch, so can be utilised. 

Not so mysterious, but at times some will turn that off as a personal preference, and forget others may not have the same preference settings.

Thanks Dave you are totally correct, I checked my preferences and under general, design, "auto project active geometry on active sketch plane" was unticked. I ticked it and everything works as expected. Thank you very much.

Just found your post and wanted to say thanks for replying with what you did to fix your issue.  It also helped me fix mine,  where I would create a new sketch but I was not able to snap to any previous sketch or body edge.  I am fairly new and didn't understand what was wrong,  it had been doing my head in for weeks.

Slightly different to you,  but I needed "Auto project edges on reference",  your post helped me find it.

Thanks!

yes, you are right it worked for me too.

That worked for me too. The strange part was that both this and  "Auto project edges on reference" were apparently active until a single face pretty far into my project. Stopped working mid-design-session too so it's not like something happened between closing and reopening. I never touched any of these settings durting the project, so why would it disable itself in the middle like that?
