Fairfax Posted August 9, 2006 Share Posted August 9, 2006 I am hoping for a simpler method to create a 3D foundation on a sloped lot. What I have been doing is using walls which I contour on the bottoms to the grade lines. All well and good, but the "ground" is transparent, so to avoid seeing the foundation from other walls in an elevation, I have found I need to create a solid-filled, no stroked 3D poly for each elevation, to mask any foundation which might appear from another side of the building. Then, I have to add the grade lines in as annotations to each elevation's viewport. Sound convoluted? I agree!!! I am using VW 11.5 Quote Link to comment
Michael_Eschenbach Posted August 9, 2006 Share Posted August 9, 2006 you might try placing a solid, vertical extruded pane, white fill and white line, running fore and aft, and another side to side, centered on the building, below the floor joists, to well below the height of the bottom of the foundation.... then when you do the renders, you will not see past that pane.

Kevin Posted August 9, 2006 Share Posted August 9, 2006 I am not sure that I follow, but here are my thoughts. I have a 3d house on a sloped lot. The foundation wall are deep enough to extend into the site. The site model has a texture and the foundation below the sites grade line is hidden. VW has the ability to automatically extend walls to a roof. You might be able to use this feature to extend your foundation walls to the ground plane. From a working drawing perspective, the footings would be stepped. I would be showing these dotted below the 2d grade line. Quote Link to comment
mike m oz Posted August 10, 2006 Share Posted August 10, 2006 Why not just make the ground opaque? Quote Link to comment
Fairfax Posted August 14, 2006 Author Share Posted August 14, 2006 Thanks for the input. To answer, respectively: 1) Interesting idea, I will try that. 2 & 3) Requires the construction of a ground plane, which seems quite difficult in the case of sloping site to get accurate, but I may explore "at my leisure." ;-) I welcome further direction/comments on this process.

CipesDesign Posted August 15, 2006 Share Posted August 15, 2006 (edited) To make 'quick & dirty' 3d ground is really easy. Simply go to a side view and with the polygon tool draw the site profile. Add some depth below the 'grade line' and make sure the poly is 'closed'. While still in the side view select the the poly and extrude it. Make it 100' (or whatever) deep. Now go back to plan view. Ypu can drag or stretch the extrude from here to adjuact its extents. When I do this I usually create a new class just for this extrude so that I control its visibility (or lack thereof) in various different views & viewports.

Don@Black Dog Posted August 24, 2006 Share Posted August 24, 2006 (edited) Peter: I tried this but could not use the polygon tool with stacked layers, which I need to see the whole building. Realizing it is quick and dirty, do you just wing it, or am I missing simething? Wait! Just tried it with the double line polygon. Mahvelous! Still have the stacked layers question, though... Thanks Don Edited August 24, 2006 by blackdogarch Quote Link to comment
CipesDesign Posted August 24, 2006 Share Posted August 24, 2006 Don, for the moment "stacked layers" is more of "viewing" mode - many tools are not useable while stacked layers is on. If you temporarily turn stacked layers off you can create the 3d poly (or extrude, or floor, or whatever) to represent your ground, then turn it back on to view everything in context.

panthony Posted August 25, 2006 Share Posted August 25, 2006 Don, Peter, Using the 3d polygon tool when in "stacked layers" is the way to layout your gound poly. This way you can visualize the slope of the ground in a 2d environment while you draw in 3d reality. Once you have the closed 3d polygon, switch off stacked layers then convert the 3d poly to a 2d polygon (Modify -> Convert -> Convert to Polygon command). When you have it in this form than you can do an extrude and position your solid where you want. Be aware that when you shade the 3d poly you will need to set its class attribute to solid for shading to take affect. See graphic below. I did this simple ground mass in about 30 seconds.

panthony Posted August 25, 2006 Share Posted August 25, 2006 If you are needing to present using hidden line than you will need to extrude a solid of the foot print and use subtract solids to achieve a good hidden line around the model. See Picture below Pete Anthony Quote Link to comment
