Help with line work / alternate work bias
-
Hiya,
I have two questions.
Say I'm making a two story house model... The floor plans have two biases. The first floor is on the regular orthogonal grid, which is reflected in Sketchup's three default axes. Work on this level is easy due to Sketchups inference.
But I have a 2nd plan (the second floor) that sits at a 50 degree angle. How do I get lines to extend along that bias? If I try to move the end of a line, it wants to follow the orthogonal bias (which has no reality in that plan) or float off indeterminately.
I'm already using layers to separate the two levels, for ease of use.
Thanks ahead of time.

you could easily build the second floor square to the first one and then rotate it when your done with it, OR move sketchups axes to match the second floor while your working on it. to place it simply right click on the red green or blue line and choose move, the click onme of the corners on your off angle geometry and double click down one of the edges>

Yes, that's not bad for when I started the design, but once smaller features need to correspond between floors, it's a problem. Sketchup is only for use with right angles?
-
there is parallel and perpendicular (purple line) inferencing as well if you hold (hover) your draw tool over an edge. if those two solutions don't work for you then you got me. oh, one more thing that may help is construction lines. make them with the tape measure and protractor tools.

here is a construction line and a parallel inference:
here is a perp. one:
-
What if I made a grid out of construction lines whch would give me a bunch of reference points to use (and put it on its own layer)
...which brings me to a related question. Sketchup doesn't let you offset just one line. You always have to slelect two lines. I don't understand that limitaton. Is there wa way to just offset one line?
Thank you for your ideas and assisitance.

just copy it, which is the move tool and press ctrl you will see a plus sign by the tool.
i don't think a grid would work that well unless you just want things close or everthing is an exact multiple. the whole point of inferencing is so you don't need grids.PS construction lines don't have points.
i think someone needs a "sketchup basics" refresher.

I'm self taught, with some of the Aiden Chopra vids on YouTube. I don't know much about const lines. But wouldn't the point where two construction lins cross make an inference point?
-
yes
-
but if you insist that you want a grid just drag one out with the "sandbox->from scratch" tool?

Hi Count,
Above, xrok suggested you to adjust the axes to the second floor but then you both dropped that idea. I'd still go on long this.
Have a look at the attached file where there is a separate group for a first floor and another group for the second floor rotate by 50 degrees (that was it, right?). For the second floor I adjusted the axes so they now match with the alignment of the group. Then I created two scenes. In one scene the axes are aligned with the first floor while they are aligned with the second floor in the second scene. You can even switch scenes between operations and get your axis inference different between the two scenes.
Note that in the Scene manager (Window menu) I turned off Camera location (to save with scenes) so when you switch between them, your viewpoint won't change.

Great suggestion for use of scenes Gaieus, and solves the struggle with bias modeling.
In the past I have basically modeled the whole upper floor group with the axes normal, then rotated the whole upper floor group when complete, and dealt with features like stairs etc that affect both floors. I like your method better. -
very nice tip Gaieus, i didn't know scenes would save the axis location. thanks.

They save many-many things; check out the scene manager and the first quarter of this presentation (you may realise that you know all the presenters there
)
