Wall Projections

[Kevin McAllister]

Hello,

 

I'm having some trouble with wall projections. I've never really used them before but they seemed like the right tool for the job. However they seem a little buggy. Two examples -

 

1) First a display issue. The hatches from the wall protrusions (in the green circles) sometimes jump into a pile at the origin. Is this a known bug?

 

2) How do you solve the corners so you don't have the extra line?

 

Wall protrusions are pretty common in real life and there doesn't seem to be a nice clean way to draw as built architecture in VW. I really wish I could draw a poly "outline" of a wall and convert it to a wall-like object rather than trying to use a bunch of tools that are for designing new architecture.

I tried using the 'wall projections' tool for a bit a while back and decided it was buggy enough that it was more trouble that it was worth.

 

My solutions have included just using solid modelling for protrusions and using horizontal sections instead of top/plan views and/or trying to use the annotation layer to clean up the mess in sheet layer viewports.

If the Extension only extends to one side of the Wall,

not like Walls middle between columns,

the Pilaster Tool may also work.

 

A persisting problem is that all these Projection or Recess Features

don't work well at Wall ends and counteract Wall Joining.

Thanks for all of the advice.

 

In the end I replaced the wall projections with segments of thicker walls. It made the cleanest joins and worked for my purposes since I only needed the proper footprint.

Wall Features... Great idea, mediocre execution.

Don't get me started on the problems with wall recesses and projections.  Here are the quirks I've identified.

 

1.  Trying to insert a wall recess in a 3d view results in an odd error message stating, "No Valid Feature Object is Selected.  Please select a manifold feature object."  Creating a wall feature is best done in orthogonal projection.  Working in this context I feel like I am in some sort of 3d modeling twilight zone where things are not really 2d or 3d. 

 

2.  You can't easily edit the objects once they have been inserted into the walls.  Pushing and pulling a 3d wall feature object is not possible. Adjusting the parameters of an extrude is possible (sort of), but again quirky.  If you are not in a plan view and edit an extrude parameter you can get a different error message stating, "The feature object is not overlapping the wall.  Would you like to delete the feature object?" 

 

3.  Cutting and pasting 3d feature objects back into the real model results in an offset of the feature object by the layer height.  Why would one ever want that to happen? 

 

4.  Trying to reconstruct backup files often results in the wall feature objects disappearing or not showing up.  But they are sort of still present cause they all may come back at once when you reinsert one of them. 

 

5. The wall returns and issues with plan representation have been discussed in other threads.

 

Thanks for letting me share my experiences with this tool.

Thought I'd try using wall recesses/projections again. As per my post above from 2018, never really trust these. But wondered if anything has been improved in the intervening 5 years.

 

On first attempt I can confirm that at least points 1 and 2 from @cberg's post above still apply (in VW2023 at least).

 

So it would seem that nothing has changed and maybe I should continue to avoid these features, or would I be being over-cautious?

 

There is quite a lot of stuff that I simply can't model using wall objects (at least, not without horrendously complex assemblages of small bits of walls), unless these "recess" and "projection" features are reliable. So end up having to do it all as dumb solids.
