Altium designer schematic question

I am still a complete beginner, but I would like to learn how to use Altium Designer. Sorry in advance for the silly questions.

I have the following two circuits (pic no. 1) that I want to combine into one circuit and draw in Altium Designer schematic.

I tried to draw the mentioned circuit in Altium Designer (pic no 2). At the beginning, I created a connector header. Can this be done this way in this circuit? Do I have to change any parameters? I was thinking that if I create a connector, the generator signal can be injected through it. For the inductor, capacitor, and resistors, I changed the parameters to the respective values (capacitance, inductance, etc.) shown in pic no 1. Would my circuit approach make sense? Thank you in advance.

@Harald Kapp :
I would agree with you, but then we would both be wrong .
Considering rules of thumb,, basic principles, wire line conventions. These conventions
ensures that anyone looking at the schematic will immediately understand where signals pass to and from, and which lines carry signals and which carry power. So now we are getting into the realm of opinions,preferences, just like belly buttons everyone has an opinion.
My opinion is use connection dots for two or more wires .A wire in Altium is a polyline electrical design primitive that is used to form electrical connections between points on a schematic .
Lines should not cross or converge where possible . Crossing wires creates the appearance of a connection between lines.If lines join, I limit this to a maximum of three lines. More than three lines meeting at one point could be mistaken for unintentionally crossed lines. Schematic capture is the process of arranging components in schematic sheets and defining links between them.Altium doesn't care about how you arrange components into schematics. Circuit simulation packages like SPICE & PCB layout tools only care about the connections you define between pins on different components. These connections are called "nets," and schematic capture is really the task of creating a list of nets that will be reflected in the make up everything in your physical PCB layout,

it isnt the world wide electronics convention .... change your opinions to align with what everyone else does :)

Lines should not cross or converge where possible .

on a reasonably complex circuit, that isnt going to happen

Crossing wires creates the appearance of a connection between lines.

ONLY if there is a dot showing connection


More than three lines meeting at one point could be mistaken for unintentionally crossed lines.

Again, dots will show connections, no dot, no connection
it's pretty straight forward :)

just an example of one of my drawings ......

Agree with you on this Dave.
Dots mean joins, no dots mean no joins.

I absolutely hate diagrams with those silly hoops where wires cross without connecting.
