grease pencil draw in 3d

Blender has a pen function chosen Grease Pencil.
In addition to writing notes and creating 2nd animations, it is also possible to catechumen lines drawn with Grease Pencil into 3D models.

In this article, I will show you how to convert lines drawn with the grease pencil into a 3D model and how to create a decorative mask.

Let's endeavor using a grease pencil

Using a grease pencil, you can create objects with complex lines in a sensible way.

Download the original model

I used this copyright complimentary model from a 3D model sharing site called cgtrader.

Click on the "Gratis download" push to download the model.
Annotation that this site requires you lot to register a new business relationship (or log in) and wait a few tens of seconds for the download to starting time.

Wait a few tens of seconds and the download link will appear.

Click "Import" from the menu in the upper left corner, and select the model that you just downloaded.

The model we will utilize is .fbx, so select this i.

The loaded model is pocket-sized, so resize it a petty.

Then, select and delete the unnecessary cameras that are included.

Press [S] primal, move the cursor to overstate, select, and press [X] key to delete.

Adjust the position of the 3D model.
Select View→Viewpoint→Front to switch the viewpoint to the forepart.

Front

Select Object→Set up Origin→Origin to Geometry from the top carte du jour to reset the middle point of the model.

Origin to Geometry

Click the < push button in the upper right corner of the main screen to display the menu, and motility the model's location to the XYZ origin.

Set all Location values to 0.

Cartoon a pattern with a grease pencil (Training)

Click anywhere on the screen to deselect the model.

Now you are ready to get.

Alter the settings of the grease pencil

Radius	Pen thickness (one to 500px)
Strength	Pen transparency (1.0=100% transparency)
Surface	Depict along the surface of the model.

Radius and Strength depend on the force per unit area of the pen tab or mouse when the icons next to them are turned on.
If you plow them off, you lot can depict lines of uniform thickness and transparency.

If yous modify the Origin to Surface in the elevation center menu, y'all tin can describe lines along the model.

Drawing lines past dragging

If you want to draw a symmetrical pattern like the model we will create, use the Mirror modifier in the Modifier Properties.
Mirror is a modifier that allows y'all to model symmetrically around the X, Y, or Z axis.

Yous tin can add some other view besides the main screen to see the depth and work easily.

You can add more windows past dragging from the upper right corner of the primary screen.

Now you can describe lines as y'all like.
Since Mirror is applied, just draw on i side and the aforementioned line will be reflected on the other side.
I used a Google image as a reference for this projection.
