Holes don't move with Component

[fsonnichsen]

I've done other moves of one component to a another-but for some reason this one does not want to carry its 'holes" with it. Try moving the "platform" to the "assembly" and the holes are left behind. I played a lot with grouping the platform components and at least in this example I have the holes, sketch and body in one component but they still will not move.

  Interestingly the single hole on the appendage moves fine.

I am stumped-

Yellow icons in the timeline are usually a guarantee for trouble. Perhaps those need to be fixed first:

This looks like its symmetric, so a better location for the sketch origin is in the middle (red circle). Only sketch/model half of it and mirror.

No explicit joint origin (red arrow) is needed to assemble this.

I looked this over a bit more--there is indeed mirror symmetry here but I think I am already expressing it in the sketch. The connection to the origin is not at the center point-but at the left side--but I don't know if this can be changed--the "delete" command apparently does not work here so I can't move it.

  That said, I know that the custom is to "lock down everything" but when I do this, components seem to become unmovable by the cursor when I return to the Design level. I like to be able to move things around to test geometry etc.

The "yellow" cautions  on the timeline are indeed a problem but it is not clear how they arise-the original designs from which components are copied are fine--but when they are copied they lose "something" and hence the yellow. I have a problem over the whole detachment of bodies from their sketches--somewhere here it was said to ignore this but it seems to become a problem later. Not sure of the reasoning behind this-

Thanks

In the Platform file, you create a joint between holes and platform.  It's totally unnecessary.  There is also no reason to have a separate component for the holes.  Why is platform.sketch1 not created on the origin? Moving it later is counter productive.

Whenever I create a sketch in a new component, I try to use the origin planes of that component for the sketch plane.  This reduces errors if you copy the component to a new file. It also helps to create the geometry on the Origin, or dimension it to the Origin.

[fsonnichsen]

I am not entirely clear here-I need the sketch with the "hole points" to locate the holes. And I need the Joint to fix this relative to the body.

  I suppose I could reconstruct the whole geometry sketching the large face of the body and placing the holes on the same sketch. But from the way I have done this originally (sketching small face of the body) it is not clear how I would place the sketch without a component and positioning it with respect to the body.

The screencast shows how I would model this.  If the hole pattern wasn't centered, then put the center point of the Center Rectangle away from the Origin and use dimensions to place it.

When you have features to add on other faces of a body, then use that face to create the sketch. Note how this was done for the hole in the 'driver'.

Holes shouldn't be considered as components, but as features.

Here's the screencast 🙄

Sorry for the late reply-

 my overly complex drawing was done in the way I thought this through--- taking some measurements, going back to the drawing board etc. Clearly putting all the sketch elements into one is much more concise and a good example of what I should be doing.

  Many thanks for your time on this
