line-weight Posted October 24, 2019 Share Posted October 24, 2019 Regarding whether the site model should be sectioned as hollow or solid (I am talking about section viewports here rather than clip cube) - there are two scenarios where different behaviour is preferable: (1) For a general site section, for example at early stages of a project, it is useful if the 'site' is shown as solid, with any buildings 'merged' into it. For these sections, what happens underground (foundations and so on) is not really important. These will tend to be the same drawings where components of walls etc are shown "merged". (2) For more detailed construction stage drawings it is more useful to have the site model effectively "hollow", so that below-ground detail such as foundations *is* visible. The foundations will likely be shown sectioned but not "merged" - in other words the different components/materials will be visible. In this scenario, all I generally want for the site model is a single thick section line representing the ground surface. In theory this could be achieved with a "solid" site model but only if that solid has any below-ground construction subtracted from it - something that is not really feasible in practice. For this reason, ideally the user should be able to choose which way the site model is sectioned, per viewport. If it's not clear what the two types of drawings I'm talking about are, I can provide examples. 1 Quote Link to comment

Im finding that i get lots of conflict alerts and inhibited model when I add a "proposed' site modifiers which cross over ' existing site modifiers. Yet this is an essentially ability. I need to use existing SM's to clean up my survey point data generated site model and then my proposed SM's are naturally going to edit these existing conditions. Is there a work around? Like a way to export a "clean" site model which integrates existing SM's as permanent edits? Once i have established existing conditions accurately Id be happy to lose the ability to retroactively edit existing conditions (and possibly make the file lighter?) once I commence design (proposed) iterations. There is an easy way. Just convert your Modificators to 3D-Polygons Copy/Paste them into the DTM Data and remove the old Terrain Data that covers the same area. As always when working with DTM's. Don't move or rotate the model after creation, like this you keep the same origin inside and outside the model so paste in place will work properly.

Duplicate the layer the Site Model is in for safekeeping the original Existing Site Modifiers (just in case, for reference). 2. Go to a 'Top' view and change the Existing Site Model to be viewed as 3D Contours. 3. Ungroup. These 3D polygons now include the shape of the modified existing terrain. 4. Select them all and use them as the source data for a new Site Model. Then there'll be no conflict between the existing and proposed Site Modifiers as the existing are gone. It begs the question as to why there are conflicts between Existing and Proposed Site Modifiers in the first place... Cheers, Peter 5 1 Quote Link to comment

herbieherb Posted October 25, 2019 Share Posted October 25, 2019 Unfortunately, with this method the DTM data becomes up to 6 times larger than necessary. With very large data sets I would create a marionette/script that extract the vertices from the 3D polygons, then deletes the doubled vertices and creates 3D-loci out of it. Then generate a new DTM out of these 3D-Loci. Quote Link to comment
Vectorworks, Inc Employee Tamsin Slatter Posted October 25, 2019 Vectorworks, Inc Employee Share Posted October 25, 2019 And don't forget the Simplify 3D Polygon command which removes many of the vertices from a 3D poly, without compromising its shape. 4 Quote Link to comment

Any chance of getting the retaining wall added to Architect in a 2021 SP? Almost every project I work on has retaining walls. I don't understand the logic of restricting this particular site modifier to VW Landmark users. Edit: Updated to request for VW 2021SP. @Tamsin Slatter, any chance this will happen? 2022? I'm assuming this is a business decision, rather than a technical issue. Do you mean the retaining wall site modifier? It's not my decision of course, but I can certainly ask. 3 Quote Link to comment

Jonathan Pickup Posted February 6, 2021 Share Posted February 6, 2021 On 10/7/2019 at 11:42 AM, E|FA said: @Kevin K I think this is possible by creating a 3d polygon and changing its class to Site-DTM-Modifier which is the automatically created class for modifiers. I believe I learned this trick from @Jonathan Pickup and don’t know if it’s anywhere in the VW documentation. it is possible and a good trick to remember when pads and contours don't work easily. Still works in 2021 I have a few YouTube moves on site modeling: https://youtu.be/vD94_FWKhW0 https://youtu.be/y3eYdickZbE 1 Quote Link to comment
