How do I make the 90º snap grab the object?

Hello,

 

I can't get the 90º snap in relation to an object (in my case, a polyline) to work.

 

See that the polar snap works with 90º, but it's not in relation to the object I want, but to the axis of the model:

I need it to detect 90º in relation to the polyline:

My settings:

There is no OSNAP to do what you are describing: PERPENDICULAR osnap is for the second point, not the first point.

PLUS you should have all of them on all the time, some interfere with others, that's not the best solution.

 

Try this tip from a similar post:

I would not recommend having the Nearest toggle button checked. You don’t want to end up with objects drawn that only goes nearest to an object snap point. Then you’ll end up with an inaccurate cad file.

It's not quite clear to me exactly what you're asking, but if you have started a Line [or a Polyline, or a Move or Copy displacement, or...] on something, you can draw or displace from there, locked into the direction PERpendicular FROM it, with the (pf) function in PerFrom.lsp, >here<.  See comments in that Topic and in the file.  When loaded, after you have picked the location on some object with linearity as a start or displacement base point [or an intermediate point along the way in a Polyline or something], the usage is (pf) including the parentheses [but not case-sensitive].

[And I agree with others that you should not include NEArest among running Osnap modes.  It will almost always "win out" over other modes, and you can easily snap to locations you don't really want, without noticing.]

Set the Z axis on the firest line  polar tracking to including 90 degrees.  second line, first point of the first line and perpendicular will be parallel to the x axis. enter a length

Using an Action Recorder Macro,  an XLine can place a reference line perpendicular to the selected polyline in the current XY plane and a line can be drawn at the desired length using that reference line as needed - see the video below.

Try these steps:

1. UCS OB

2. Select the PLINE segment you want to draw perpendicular to

UCS will change the current xyz axis to match with the segment of the PLINE you selected

3. Start your LINE command & this is where you can use the Nearest object snap to select any where along the PLINE

4. Toggle Ortho <F8> on

5. Since Ortho is on now the 2nd point of the LINE will be drawn perpendicular to the PLINE

6. After you're done enter command UCS P to return to the original UCS

Use a manual PER override mode...

Run the LINE command, type PER (or use the Shift + RT shortcut menu and select Perpendicular), click on the line from which you want to make a perpendicular line...

that's an excellent tip..too bad it can't be combined with another osnap like mid or end so then I can start the LINE at the midpoint or endpoint and at the same time perpendicular...

Yeah, that would be neat. But... with the help of F11 Object snap tracking, that could be done. Another option is to use an XLINE... per then mid.
