Lines left after erasing


#1

When I erase components, there are usually a lot of black lines and pieces of line left in the model which I then have to erase. The lines look like outlines from the components which I erased. How do I avoid having the black outlines left after erasing? Thanks.


#2

Can you please post a model that has this behavior ?


#3

Thanks for responding, Dan. The file is too big to upload. I’ll work up another one. Also, if I erase one of the mystery lines, the component associated with that line is erased also - a big disincentive not to erase lines or even dots. - Mike

Attached is a PDF picture of what the lines look like when the components have been hidden.

Your image does not tell us what exactly is occurring although my guess would be that there is an issue with the video display adapter or possibly your video driver(s) may require updating.

OK, your file is too large to send directly via this Forum so perhaps you should try to upload the offending skp file with one of the cloud storage services such as Dropbox or Google Drive. These services will allow files of larger size to be stored and you provide a link to the stored location. Then any interested party with the link address can view the file and hopefully offer some salient advice.

Or 3d warehouse…

My guess (still lacking the model) is these are lines of intersection created by inadvertently using the Intersect command while in the context of the model space.


#8

Are all the edges all on Layer 0, and are they ‘inside their Component’…

If you select and ‘Move’ one do the edges all move as well…

As you can see from the scatter of theories, we are guessing. Please follow @Box’s suggestion and try uploading to the 3D Warehouse if your model is too large for here.


#10

I’ve uploaded one of the models into 3D Warehouse under the name St. Croix House. A further note: some of the components that leave the lines behind when I erase or hide were uploaded from 3D Warehouse and some were not.

I’m surprised and delighted to have received so many responses to my posting. Thank you to all.

I trust this is the one?


#12

Yes, that’s it. Thanks.

No lines are left behind (when you move groups and/or components) other than edges that do NOT belong to these groups or components. What else would you expect?

There are lots of groups and components which make it somewhat difficult to see what is going on, to see where there is basic (ungrouped) geometry.

Unlock the few groups/components that are red when selecting them.
Next open the outliner (menu Window > Outliner)
tab the first group/componets and then the last one while holding down [Shift], to select all grouped entities. Now move them to the side. All basic edges (and if existing, some faces) will stay in place. This is how to see what was left behind in your case. Nothing wrong here.

It looks like all this loose geometry was created by using Intersect.


#15

Right. Intersect Faces > With Model or With Selection, but definitely done in top level context …> result is ungrouped basic geometry, also in top level.


#16

Here’s a simplified version for clarification.
Basically it is superfluous geometry that has probably been created inadvertently and can be removed if you don’t need it.


#17

I found some stray geometry on another layer as well.
Perhaps Layer 0 was not the active layer during the intersect command.

There might be more. I’ve no time to rummage through all 50 layers.

Geo, Derek, Box, and Wo3Dan:

Thank you all for your time, and congratulations for resolving the issue. I know you are all SketchUp veterans and probably don’t remember how confusing the program can be to the uninitiated. All the more reason why I appreciate your help.

However, I’m still not sure what I did to cause the ”superfluous” “ungrouped geometry” “in the top level” or how to avoid doing the same thing in the future.

Does creating “Intersect Faces” always result in ungrouped geometry? How do I avoid downloading components from 3D Warehouse (such as the doors and windows in this model) which introduce ungrouped geometry? Will erasing ungrouped geometry (lines and dots) always risk erasing the components it is associated with (or is that a contradiction in terms.)

I’ve been struggling to learn SketchUp (self-taught) for three months, but there is much that is still mysterious to me. Leading that list is sleuthing out when a component can be edited without changing other instances of the same “Definition Name”, “Instance Name”, “Name”, etc.

I got so lost in the jargon that I created the attached spreadsheet to try to track which type of information was referred to by which name in the different screens of the program.

As far as I can find, there are no shortage of tutorials that provide the same entry-level instruction, but few that dig deeply into the more nuanced features of the program, such as moving between levels and what editing to do at the different levels. If you know of tutorials that might help explain such features, I would appreciate your suggestions.

Best regards,
Mike

I wrote a plugin that opens a warning box to let you know this info. (It distributed by the benefactor Ash Scott.)

Most likely it is ‘Intersect with Faces’ what caused the ungrouped geometry. SketchUp doesn’t create geometry on its own unless you make it do so.

[quote=“michaelt, post:18, topic:12145”]Does creating “Intersect Faces” always result in ungrouped geometry?
[/quote]
‘Intersect with Faces’ always creates ungrouped geometry. Where that geometry is depends on when you make SketchUp do the intersection. If you are in some editing context (inside a (nested) group or component) then that is where the ungrouped new geometry will be added.

Downloading components do not introduce ungrouped geometry. All its geometry is inside that component. Nothing special.

You cannot change a component without changing all the component instances with the same component definition. The name itself doesn’t matter at all. Only the definition name.

When you create a component you’ll be asked to name it. This will be its definition name later (which can be changed at all times). The window ‘Create Component’ should have asked for a definition name, not just name which makes it a bit confusing.

You can separate (=make unique) one or more components from the others wit the same definition name by right clicking on it (them) and selecting ‘Make Unique’ in the appearing right click context menu. It’s (their) definition name will be changed by SketchUp adding #1 to the definition name. From now on it (they) are on its (their) own and can be edited independently.
