How to fill the space between objects?

[Anonymous]

Hello,

I created a case for an PCB. I would like to fill the empty space in the outline. How can I do that? I use AutoCAD 2019 student edition.

In the attachment I added my sketch.

Kind regards,

Chris

Are you trying to use HATCH? If so, turn on FILLMODE, it's set to 0 and needs to be set to 1, and your current layer (Bodem) is off. Turn that on also. You'll see that you already have some HATCH objects there. You could have determined this by selecting ALL, then looking in properties to see that HATCH objects exist in the drawing.

Not sure which area you're trying to hatch.

Since you have SURFACEs up into the 3rd dimension, apparently you've EXTRUDEd them from the underlying objects.  If you want to fill that as a 3D SOLID, delete the SURFACEs.  You'll need to do some cleaning up of the inner shape -- things don't quite close right.  But once you get it so it will JOIN into a single closed Polyline, you can use PRESSPULL to make a SOLID of the space between the outer CIRCLE and the inner shape, to whatever thickness you like.  You can do the same with the space inside the inner shape, if that's what you're after.

Thank you for your replays. I converted the inner circle to one polyline. But I don’t understand the PRESSPULL command. I can only use that on the outer circle. But that  I would like to make the space between the inner and outer circle in 3D. Like @rkmcswain first drawing with that yellow but then in 3D.

See if this looks like what you want-

I had to do 2 things to get it to work:

1) Un-Group the inner polyline

2) use command "flatten" to put all object onto the same Z-plane (they were at different Z values)

Hope it helps.

Hello @Anonymous, 

Well, let's go step by step on the simplest side according to me.

1. Taking into account that you are going to create a volume, I suggest you leave the least amount of points so that the solid does not have too many faces.

Polyline (closed)
2. from the TOP route use FLATTEN command to make sure that all the lines and arcs are in the same plane.
3. Using PEDIT we will convert everything to closed polyline, you could use JOIN but sometimes create a spline instead of a polyline.
* In this case, the geometry you attached was not completely closed, in those cases when extruding surfaces are created instead of solids.
4. Once it is closed, with EXTRUDE we select the outer circle and the polyline, creating two bodies, then using SUBSTRACT you select the outer body and subtract the inside.

Extrude Substract
Attach file dwg with the settings I made in the polyline.

I'll be careful if something was not clear,

Thank you this is exactly what I was trying to create.
