Sketching Lightweight

[fishtruk]

That's me. I have a sketch. I want to modify it. I draw new lines and arcs of the modified sections using the parts that don't change.. The new things I draw aren't yellowed in as the closed surfaces are. What's the reason for this?

Hi there!

If you are trying to edit a sketch you should right click it and choose edit sketch. If you are simply creating a new sketch you are just adding lines. Can you confirm that you are editing a sketch?

If you are editing a sketch though, can you please include a screenshot of what you are trying to do please?

Thank you,

I've tried

editing a sketch "layer" but do all elements have to be in the same sketch?

Hey!

Yes, in order for the sketching engine to create a profile, all sketch entities must exist in the same sketch. You can project existing entities into your current sketch and use those to make a profile - and it looks like you have done that - but you cannot edit projected entities. In other words, if the line is purple, you cannot modify it.

I am guessing the purple sketch on the right is what you are trying to edit? I can't tell from the image, but likely there is a point or a line that is not connected causing it not to create a profile. If you would like, you can attach the .f3d file and I can look at it. Can you tell or show me what you are trying to accomplish?

We'll get it worked out!
Best,

dats right-lightweight.

I found that the little bit at the top was missing a line segment.

I can't modify the purple because??

[xander.luciano · Accepted solution]

Purple is project geometry, meaning that it is created/defined by either another sketch, model geometry, etc. If you wanted to edit the purple entity, you would have to edit the geometry they reference. Alternatively you can add points to the end of a purple line/arc/spline segment and create a new line/arc/spline with it's endpoints and edit that.

Referenced by another thing. That really helps understand it. So Offset lines would show purple also I guess. I wondered why I can't offset an offset line as before in Acad.

[xander.luciano]

Offset actually isn't purple - even though it is referencing another geometry, it isn't "attached" to that geometry directly because you can edit the distance it is offset.

I guess another good way to describe it would be that purple is the direct geometry from another feature. So if you make a line that starts on the midpoint of something NOT in the current sketch, that geometry is "projected" into the sketch, that way it is linked or referencing the other geometry.

You cannot edit purple lines
Purple lines will update when the object they reference is updated.
Purple entities act as if they are part of the sketch in that they can be used to constrain geometry.

Sorry if it's a little complicated - It's hard to explain well. Would you like me to make a screencast to show how they work for you? Maybe that would be the best option.

Also, I have never noticed that you can't offset an offset line. Though if you need to, you can just offset the original line again. I'll have to look into that some more.

Best,
