The ability to select a face and draw a line, freehand, rectangle, whatever, and all other geometry you “draw over” or touch is considered invisible as it relates to the drawn geometry. Regardless the geometry “sticks” to the face designated. Sometimes you want to outline something or create an intersecting line without actually intersecting the whole face.
How many times have you drawn a line on a face only for it to get jacked up by barely touching another geometry unintentionally.
Once you learn how to work in SketchUp this isn’t a problem. If you don’t want newly created geometry to stick to or intersect with existing geometry, group the existing geometry first. Very often I will create geometry outside of a component that will eventually be inside the component so it doesn’t merge with the existing geometry until I’m ready for it to do so. This is trivial with keyboard shortcuts for Cut and Paste in Place. Sometimes that geometry gets used in adjoining components so it’s easy enough to paste the geometry into both components without having to draw it twice.
Are you still using SketchUp 2021?
Hi - thanks for the response. I group everything. It’s not sticking to the touching geometry, the joining geometry is effecting the path of the line.
Here’s an example. Let’s say you have a wall, and it’s a group. And you have baseboard on the floor against the wall and that’s a group. If you open the wall group and create a rectangle without touching any other geometry you’re fine. If the rectangle even touches the edge of the baseboard group it messes it up. (ignore that fact that the bad one doesn’t look like it was drawn perfect - that’s just a sketchup rendering artifact) Is was drawn perfectly on plane.
If you open the wall group up and add geometry, it cannot and will not interfere or intersect any geometry outside the group, or any other group.
@cbizy , your example shows a baseboard group with hidden edges. SketchUp won’t find any edge that is hidden. (No ‘On Edge outside Group’ inference).Turn on ‘View Hidden Geometry’ before drawing the rectangle.
Does that solve the problem?
I think that’s just the screenshot not picking up the lines. But here’s a snippet of the model - if you want to try to repeat what i did and see if you don’t get anomalies.
wall.skp (1.4 MB)
(I’m on the phone now so can’t t see your model)
In that case I can only assume that the top back edge of the board is not in the same plane of the wall’s face.
