NCSMITH Posted September 29, 2017 Share Posted September 29, 2017 Hello all, Fairly new to VW and doing some tutorials to try and understand the 3D modelling tools a little better. I've got stuck and haven't managed to find any other posts which could solve the problem. I'm trying to use 'subtract solid' tool- I've highlighted the objects and the subtract solids option in model bar is greyed out- scene shot attached. Any tips? Many thanks! Quote Link to comment
zoomer Posted September 29, 2017 Share Posted September 29, 2017 A hurdle I ran into sometimes is that all objects have to be on the same (active ?) Layer. Otherwise the Menu Entries are grayed out. Quote Link to comment
Art V Posted September 29, 2017 Share Posted September 29, 2017 You can run the subtract command when objects are on different layers, at least it does not get greyed out for me if editing across layers is enabled, but it will generate an error message stating that the objects have to be on the same active layer. It could be that one of the objects is not compatible for add/substract/etc. solids, e.g. because it is not a solid. Is the central object a solid or an open item in which you want to have holes? It is a bit hard to see on this image. It looks like a solid, but might not be. That could explain why the items are greyed. Quote Link to comment
zoomer Posted September 29, 2017 Share Posted September 29, 2017 Normally you get a warning that there were objects not possible for subtraction that have ben deselected, ..... (?) Quote Link to comment
Art V Posted October 1, 2017 Share Posted October 1, 2017 (edited) Can you check if one of the objects is a NURBS object (or perhaps several NURBS objects)? I tried a few things where the options remained available but when one of the objects is a NURBS object then the items do get greyed out in the menu.

Phil hunt Posted October 1, 2017 Share Posted October 1, 2017 I have had this problem and as said the 2 items have to be on the same layer or it could be something to do with the items being grouped.....you may have to ungroup and then select all in the items that have been ungrouped and then add solid command......I have had to do this on a couple of occasions.......hope I have explained this correctly Quote Link to comment
NCSMITH Posted October 2, 2017 Author Share Posted October 2, 2017 Hello all, Thank you for your responses. I've checked the following: - all objects are on the same layer - objects are not grouped - The central object is solid object (not nurbs) I have the spotlight 2017 version of VW if that limits my access at all? Otherwise anything else to try? Thank you ! Quote Link to comment
Gadzooks Posted October 2, 2017 Share Posted October 2, 2017 A quick fix could be gained from you uploading the file. Is this something you could do? Just trim it down to the objects you have shown, or copy that whole cluster (its not a group!!) to a new file. Quote Link to comment
NCSMITH Posted October 2, 2017 Author Share Posted October 2, 2017 Hey all- I managed to get there by going back a few steps and re-drawing the squares. I think perhaps the shape I wanted to subtract from the solid was not 100% aligned on the face of the object and that could have been the issue. All sorted now but thank you so much to everyone for your tips! Have a great day Quote Link to comment
Art V Posted October 2, 2017 Share Posted October 2, 2017 Good to hear you got it sorted out eventually. The odd thing is that even with non-touching objects the add/substract/etc. menu items were available in my case. Only with NURBS or the grouping as mentioned by Phil would grey it out. Are you perhaps using VW2018 or an older version? Quote Link to comment
Phil hunt Posted October 2, 2017 Share Posted October 2, 2017 maybe I'm wrong but I don't think the objects have to be aligned....you should still get some kind of a shape from the subtraction.... Quote Link to comment
Art V Posted October 2, 2017 Share Posted October 2, 2017 No they don't have to be aligned, at least not in VW2017, but maybe things have changed in VW2018 that causes it to do this, hence my question based on the original poster's solution/guess of why it failed. Quote Link to comment
