# Draw floorpan to extrude?

I'm new to Blender, coming from an arch vis background. Is there a way to draw a series of walls using some sort of spline / path tool, with a degree of accuracy, and then extrude to create walls?

All the tutorials I've watched simply show people rescaling planes and the like - I haven't come across a way to accurately input wall edges?

Thanks,

Derek

• What you could do is draw your walls on a plane with single edges, then bevel them to give thickness, and extrude up, I'm not sure it's very interesting compared to playing with some parallelepipeds, but maybe give more details? Oct 2, 2019 at 7:14
• Thanks. Not sure how to post an image showing what I'm after, but say I imported a CAD floorpan of a building. Would I be able to somehow have this as reference, and then trace out the walls to create extrudable elements? All the tutorials I've watched just seem to suggest we build stuff up by eye, using rectangles. Often buildings aren't that simple, and we need some accuracy. I can't see any sort of 'spline' tool in the Create tab - Path and Bezier Curve don't seem to achieve it, from what I can see... Oct 2, 2019 at 8:44
• you can extrude curves and solidify them to give thickness but I'm not sure it's more convenient than rectangle meshes, and anyway a curve can't have several branches so it won't simplify the work Oct 2, 2019 at 8:49
• So is there simply no way of drawing a 2D polygon from scratch in Blender? Sounds like I have to edit a plane, or else import one? Oct 2, 2019 at 9:09
• please show some pictures, it will help to have a real case... Oct 2, 2019 at 9:11

Just start from a single vertex (make a plane and delete 3 out of 4 vertices) and extrude it like so. You can make sure your vertices are aligned by turning snapping to grid ON, or selecting multiple vertices that need to be aligned and scaling them to 0 on the relevant axis.

Once you finish your shape, select all vertices and press F to create a face, then use the Solidify modifier or extrude the face.
