workfeatures understandable tutorial

[HarryGeier]

hi all,

i ave been playing with workfeatures a while, looked at all the tutorials...which are just music and llightnig fast skill demos.. no tutorials AT ALL

Who can explain me in SIMPLE terms.. how to do this :

create a rectangular base block and use workfeatures then to create a prism hole with the extends at the midpoints of the side.
I can create these points with workfeatures.. but HOW can i then sketch the prism referencing these points.. i can´t use them..not directly nor as external geometry...

Anyone who can tell me how ????

To make workfeature's geometries visible to sketcher, they have to be moved outside workfeature's group.

Really? I can import CenterFace001 vertex from your project as sketcher external geometry without any drag-dropping...

Really?

OMG, you are right. Feel free to nominate this for Trump's Fake News Award

If you are talking about the features in the Part Design workbench: Did you have a look at the tutorials of bejant https://www.youtube.com/watch?v=t-6q0iBV-50 and the channel of Roland, who sadly died in an accident but left a wonderful series of tutorials at the youtube channel BPRLFE.

Not sure I understand you correctly, but you don't have to use WorkFeatures to do that. Is this what you want?

Thanks for all the replies so far..
but:

UR_ your sample is not what i asked.. i asked about part design .. i added a sample myself to clarify...
UR_ & DEEPSOIC : I tried , still no luck .. you can see in my sample.. i also tried that before i asked and needed some hair replacemen..
chrisb: I will look into the linked tutorial later today. this one did not show up when i searched.. as well as none from Frank , whom´s fine tutorial i
looked at long time ago ... i am no newbie.. but i cannot remember if he ever mentioned the 0.17 Version of workfeatures.. if someone
knows where he shows that in part design 0.17 .. i will enjoy his voice ..surely....
bejant: I know , there surely are hundreds of ways to do that .. i am relatively professional in CAD ( Autocad since earliy 90´s and Solidworks
since1997 ) and have constructed hundreds of things in my life.. i choose this simple construct just as a sample

UR_ i cannot move any of the points into the scope of the curretn body where sketch0001 lies, which should reference the points
I i try , they end up at the root of wfProblem

Harry, I'm sorry to have misguided you. Since it was one of your first posts I had assumed you to be a newbie talking about features in Part Design speech.
There are no extensive 0.17 tutorials yet AFAIK.

Sorry, had overlooked phrase "Part Design" in your post.

Should work with "importing" a WF point by Shapebinder.
