Jim_Allen Posted October 2, 2006 Share Posted October 2, 2006 I am trying to create a working drawing for a column. It is 4' high, 180' round. 1/2" plywood top and bottom, supported by 2x4s. I have the sructure but cannot figure out how to apply, or create a facing for the round structure to be able to apply the texture. The simple question? - how can I bend a piece of lauan to 180' to apply it to the supporting structure. Jim Quote Link to comment
Ray Libby Posted October 2, 2006 Share Posted October 2, 2006 Sorry if I don't understand and this is too simple. In plan view, draw 2 circles to represent the inside and outside radius of the plywood. Modify menu > Clip Surface. Extrude to the height you want and give it a solid fill, apply your texture.

Jim_Allen Posted October 2, 2006 Author Share Posted October 2, 2006 That is what I did for the set design rendering.I created a 180' circle arc, extruded to 8' and applied a texture. Now I am faced with doing a working drawing that shows how this set piece is built. Interior support 2x4s,top and bottom, and facing. I have the 3-D piece created with the top and bottom 1/2" plywood pieces and the verticle 2x4s, but I cannot figure out how to create a 180' circular facing to put on the front of it so my students can see how it should look. My goal is to be able to show it from the front and then rotate to show the inside from the back and how it will look when built. Maybe this can't be done??? Quote Link to comment
alanmac Posted October 2, 2006 Share Posted October 2, 2006 Do a solid subtraction. Create another column with the thickness of the material used taken away or added and subtract it from the column. It will now give you the "skin" Alan Quote Link to comment
propstuff Posted October 2, 2006 Share Posted October 2, 2006 Ray's suggestion will give you what you want. The Clip will give you a polyline which is the effective cross section of the facing sheet (as long as the original arcs had a solid fill) Or draw the inside and outside arcs, join the ends with lines and Compose. Just extrude that. Alan's method will give the same 3D shape but it will be a Solid Subtraction object rather than an Extrude object. Quote Link to comment
mike m oz Posted October 2, 2006 Share Posted October 2, 2006 Jim - Create the 'skin' with the Round Wall Tool with its thickness set to 1/2". - Create a 2" x 4" vertical stud by drawing the plan shape and extruding it by the required height. - Use circular array to place the required number of studs around the back face of the 'skin'. - Draw the bottom plate profile in 2D and extrude this by the required thickness. - Copy this bottom plate and then Paste in Place a copy. Use Move 3D to move this to the correct height. You can control the appearance of the 'skin' and structural framing using Classes for each. Quote Link to comment
Jim_Allen Posted October 2, 2006 Author Share Posted October 2, 2006 GOT IT !!! Thanks for all the help. Just in time for the shop class :-) Quote Link to comment
islandmon Posted October 2, 2006 Share Posted October 2, 2006 One other thing ... make sure the plywood is rated for shear and that you create a box truss with shear panels on both the outer and inner surfaces. Quote Link to comment
