Convert surface to solid using another solid

    Well, lets give this a go and see.

    Usually in any molding, constant wall thickness is the most desirable but with a few caveats which i have no intention to enter into here...this reply is addressing ' to make a matching solid'

    Select the surface and PULL it in an appropriate direction and amount. This should make a solid.

    or...

    Copy the surface

    Move copied surface in direction to make an 'underside' thickness. The distance is your decision.

    Select both surfaces, press key 'b' ( Blend) and check the 'tick'. This should make a solid.

    If you do not have a solid, then i have no simple answer for you and the answer ends here...

    If you have a solid, then now the removal of interference volume from the existing volume is necessary.

    Press key 'I' ( Combine is the command but - 'I' stands for Intersect ) anyway, select your created solid as the target object, ensure 'Keep Cutter' is checked. Curser now has additional saw icon, select the other (original) object and where the two object intersects, one or many other solids are created. Solid bits not required can be deleted within the 'I' command or alternatively, escaping out of the command,  select solids from screen or structure browser and deleting...

    Hope this helps...

    As Tim explained, a 'surface' needs a thickness.

    You could try selecting all of the outside lines and do a 'Fill' this may create a solid. Then use the 'Shell' tool to give it the thickness you want. I would then 'Pull' the resultant edges to make it slightly bigger, then use the 'Combine/Cut' tool to 'Cut' the original solid from the new solid.

    If you are willing to share the 'SKP' file then I will have a look for you. If you cannot upload it here then use https://wetransfer.com No need to register just paste the link here.

    I appreciate the help but was unsuccessful. The pull command says Error and I couldn't figure out how to use move.

    I uploaded the model to https://we.tl/t-ED35uA65ix.

    The only suggestion that I have is to use the 'Geometry' you have now and use the 'Spline' tool at certain points across the model then use the 'Blend' tool.

    Very easy with the Shell Bottom. Use the Spline tool at the center. Pull out both sides to the edge of the seat to make into a solid, then use the 'Shell' tool for the thickness. Round over the corners to suit. It will give you a smoother model.

    It will depend on how much detail you need for the seat.

    No Joy with the SKP file. I can't use it.

    Instructions for above.

    Use the Geometry again to make the seat with the Spline tool.

    Thank you for taking the time to look at this. It'll take me some time to understand what you did since my skills are limited to Tinkercad. I didn't create this model. I downloaded it from the manufacturers website.

    Not a very good model, from the manufactures website. A SKP file!

    Care to share their link?

    Is it a copy of an 'Eames' chair?

    Place a new Sketch Plane on the edge of the 'Seat', pick the 'Move Grid' tool from the bottom of the screen. Pick correct direction arrow and move 'Upto' the middle of the seat. Use the 'Project to Sketch' tool to pick the flat inside edge of the 'red' frame. Using the 'Spline'tool, Draw around the shape, starting and finishing on the straight line, picking each of the intersections. Press ESC when on the last point. Select the 'Pull' tool, a surface should be created. If not, then the ends of the spline are not touching the ends of the straight line. Go back to 2D mode and adjust the lines so that they are joined.

    Use the Pull tool with the 'Pull both sides' option 'Upto' the end of the seat.

    Right click in the drawing window 'Use Last Sketch Plane'. Move this Plane using the 'curved arrows 90°. Move again by dragging the Plane away from the model. Make visible the 'seat frame' Using the 'Project to Sketch' tool pick the closest inside edges to the plane. Draw a shape outside of this to create a surface. Pull this surface to 'Cut' the seat. as shown in the bottom image.

    Good guess! Yes, it's an Eames chair. Here's a link to the original model: https://www.hermanmiller.com/resources/3d-models-and-planning-tools/product-models/individual/eames-lounge-chair-classic/

    Not much better from the Autocad 3D File.

    What they have used is a technique known as 'Phong Shading' as used in many 3D game files https://en.wikipedia.org/wiki/Phong_shading 

    With this type of faceted model, the best you can do is use the geometry that is there and draw over it with the Spline tool.

    Thanks again for trying! I really appreciate it.
