New user where to begin?

Search "Context" and "Universal" in Tool Search window and you will find the "Context Loop", " Universal Loop" selection tools and the related tool scription.

The "s" under cursor indicates Snapping is enabled.

You can freeze selected vertices, vertex mode > View > Hide.

Nice! got the info in the tool search...this will help allot as I am going thru the functions.

Last questions for this week....what is the process to make, build the "glass" (got it done with draw mesh > patch).

and the bottom (patched looks messed up but I dont know...new to this kind of modeling) and the circle?

Also
How to move a point and all the others will follow with (red line) the one at the end (in yellow remains at its location)?

I tried several ways but I need that one point stays as a pivot point...

Tnx!

You can use the "Subobject Transform Slide" tool, https://youtu.be/oPdWZ4IrkuE.

For the wheel well, use the Cut tool to cut out a circle. Remove the geometries inside the circle. Then use edge edge extrude tool to extrude out the well. Or you can create a cylinder and use the boolean tool.

You can build the bottom part mesh manually.

Hello back again at it.
I tried a few things and got stuck and do not know how to fix.
Questions:
1.When I do the boolean it does cut it but always the faces remain and I have to remove them manually.(boolstack.jpg) is there a way to cut and remove everything?
2. You say cut with circle the only thing I got close to a circle is the N-polygon...How to cut with circle?
3.Is there an offset tool...let say I cut something I offset the lines or to add other lines (offset.jpg)
4.Can the push-pull tool be used without trying to snap...I could not figure out this...it always seem to snap to a certain number/distance.
5.Attached boomstuck.jpg something I am trying to do here...I cut it remove the side now they are open and I cannot fix it. if the lines where I cut are blue I can use drawmesh to create a blue plane which is suppose to close it but for some reason it did work(seemed to work before). after snapping it just do nothing and disappear.
If the lines are white and I click it and I try the same draw mesh it move the lines and create a mess.
Bridge cap the solution?
6. How to create a "fillet" at the corner indicated by red arrow?
7.How would you draw lines to also patch it manually?
from the draw mesh I used the lines and convert lines to mesh to get the shape started (like the tutorial)...but got stuck with the questions above.
8.Line colors remain to remind you what was done or can these be changed?
9.How do I select line if I did a chamfer instead of selecting the small pieces?(chamfer slection.jpg)

Tnx!

As I am moving along trying to understand more.
If you have multiple points selected can you align then instead of doing one by one?

1. Which Boolean type did you used? A-B?
2. You can create an n-polygon and put it behind. Use it as a visual reference shape for cutting out a similar shape on the mesh you work on.
3. You can use this tool, Create Offset Spline.
4. Once the extrusion is created, Tap "Alt+Space".
5. It could be a bug, but I couldn't recreate it. Can you send me the scene file?
6. What is the 'fillet' shape you want to get?
7/8/9. Can't get what you mean. Can you explain in a different way?

You can use the scale manipulator or one of these tools, Align_X, Aling_Y, Align_Z.
