New user where to begin?

What do you mean by saying "with mouse only" ? Do you mean without using the keyboard?

Hello
Yes ...when I saw the Nvil video on steam
It stated mouse only...modeling pretty fast... nice stuff.

Tnx for the video's!

The title is a bit misleading. To activate a tool, you need to click a button/menu or press down a hotkey.
Hotkey was used in the video. Hotkey was not displayed out in the video.

Hello.
2 modeling question...I am practicing trying to model the attached gravity racer.
1.What would be the best method to model from an exact shape from an dxf 2d shape? attached.
...how would one, if possible extrude that imported shape? if not just try to shape the primitives as closely as possible?
2.Is there a fast way to increase the polygons of a model?

Thank you!

1. Can you send me the dxf file?
2. See if these two tools can help.
   A. Polygon modo > Geometry > Subdivision.
   B. Object mode > Geometry > Common Command n Tools > Increase Mesh Density. At 0:30, https://youtu.be/kSldy5gAJmY

Maybe I did not explain it well
attached what I want to do..if even possible...
increase the loop cuts(in blender you can scroll the mouse to increase the amount of loop cut)
...create the basic shape with low counts then increase the cuts/faces count...so I can add better details
What are the options?not triangulated

Attached dxf.
Tnx!

1. 1). Import the spline from the dxf file.
   2). Make sure the spline is selected.
   3). Go to vertex mode and select all the vertices except those corner ones. In Visual Tools window, uncheck the "Line List" box to change the spline type. Then click "Naturalize Selected Vertices" button.
   4). In Tool Search window, search this tool, Spline_Extrude_AxisDir. Click that tool to activate a temporally streamline tool.
   5). In viewport, click and hold LMB then drag vertically the extrude out a mesh object from the spline.
   6). While still keep LMB pressed, [Scroll or Alt+Drag]/[Space+Scroll or Space+Alt+Drag] to set segments.
   7). Release LMB to finish the operation.
   . Tap Esc to exit the tool.

2. There are quite a few loop generating tools. You can find them by searching in Tool Search window with key word "Loop".
   Check this video at 0:33 & 2:16, https://youtu.be/79Va6qBI9OM.
   A simple example with the default setting. 1). Move cursor overt highlight an edge.
                                              2). Press and hold "S" to activate the "Loop Cut/Slid" tool.
                                              3). Click and hold LMB to cut out a loop.
                                              4). While still keep LMB pressed, [Scroll or Alt+Drag] to increase/decrease number of cut out loops.
                                              5). Release S key and LMB to finish.

One more question to get me going and practicing this week

The colpase sub D button seems to devide the segments...
but what is the real purpose for the colpase sub d button?

I did try to find it the help file but could not find it...and does it make sense to have a button to undo or revert? I did manage to undo via the tool search.

I do not know if this is the correct way...but I am playing around try to make different shapes to get comfortable with this..

Tnx.

Purpose 1: It is subdivision work flow. Working with much less geometries to build a model. Then collapse it at a certain level of subdivision to get the final model.
Purpose 2: Collapse a model in subdivision to get a particular shape for further modeling process. For example, Create a perfect cub. Create a subdivision  vision(Geometry > Subdivision > Level 3. Now you have a special sphere which you can use as a primitive to create something.

You can use the "Reverse Subd" tool to get back to the original model from a collapsed model. But it is impossible to get back to extract shape of the original model.
