    Modo and FZ are great companions.  I use modo for complicated organic subdivision cage modeling (because it has really good soft selection tools) and then bring the object into FZ where I convert to subdivision and then convert into nurbs.  Works really well at creating super complicated organic nurbs shapes that can then be further worked on in FZ with booles etc.  Many parts of the mech were done this way (some are pure FZ hard surface modeling.)  The parts in this model ended up as separate nurbs solids exports for CNC machining.

    Woah!

    Incredible model that Setz! 


  2. Agreed.. This would be a great feature. I copy and paste on a regular basis just as you described from imported drawings where the data is kilometres from the origin (usually survey drawings). For years I've been able to work around it but it would be nice to be able to do as you say.

    Just a quick tip using the "Add Reference File" function; This is useful when I get DWG files with xrefs

    Import the main dwg,  > when it's imported move your cursor over the part you want at the 0,0,0 origin, > write down the coordinates at the top left of your screen, > close the file and save. Go to "Add Reference File" in the file menu, > select the file you saved and you'll be prompted with the placement coordinates, > put in the coordinates you wrote down with a minus in front and the file will be placed over your origin. Do the same for all the xrefs and they will all go in place. Any future updates to those dwg imports will automatically update.

    I usually do a bit of cleaning of the imported files first to get rid of unwanted rubbish and the stupid amount of layers that come with Acad files.

  3. In my experience this is down to object resolution so by converting it you inadvertently increased the res.

    But you'd need to upload the original model to really tell what's going on.

    One question about the design. The sides of the object looks concave which is expected when twisting an object such as this (parabola effect).

    If you want the sides to be at 90º, then copy one of the large faces (already twisted) delete the object, paste the face and add thickness.

     

    You can add different materials to faces by pressing the command key in conjunction with the paint tool.


  4. I had a look on the oldest installed version I have (6.7.3) and can't find it in modelling or draft mode so if it existed it must have been a script although I never had it.

    The current plugin place is LAB (and ¢hris £und of course!)

    You might just have to do some bisecting to get what you want setz..

  5. Glad you got it solved Bo. 👏

    Get your moneys worth I always say! I'm on a 7 year old iMac and a 12 year old MacPro (which is still motoring along nicely).


  6. I just thought I'd post my experience with the Maxwell V5 Cloud rendering option.

    I went to render on the Rebus renderfarm but they don't support Maxwell 5 yet (they said a few more weeks), so I tried out the cloud render option straight from FormZ and I have to say I'm very impressed so far. In the Display Options in FZ, select the Maxwell tab as normal > choose Cloud Render in the "Launch Application" drop down and hit render.

    The mxnetwork app is then launched, where you just have to log in and name your project. Your file is automatically prepared and uploaded and starts rendering after that.

    The great thing is that your render can be previewed after about SL 7 or 8 and can be stopped at any time to be downloaded thereafter. This takes out the guesswork compared to other rendering farms where an SL or cost limit is set beforehand.

    While it is not quite as fast (during the rendering stage, but nearly) as some of the other farms, it is way more friendly to use and is integrated into FormZ very well. No more time preparing a project for upload.

    If you're on Maxwell V5, give it a go.

  7. I'm not having problems selecting objects or their faces when behind other objects in wireframe.

    I typically use autopick in conjunction with the command key and/or shift. In autopick with command key, select the first edge of the face you want and then the second edge so it knows what face to select. I think having selection preview on is imperative when using autopick, otherwise how do you know what it's going to select?

     


  8. Yes, the "mxed.app" is for the materials as in the video earlier.

    The "maxwell.app" is the actual renderer.

    There is a video shown earlier for Studio but you don't seem to have that installed.

    Also, you need to check your FormZ plugins folder for the MaxwellZ plugin. If you go to the FormZ Pro folder in Applications >Plugins, there should be the Maxwell folder with the plugin. Then you can access Maxwell straight from FormZ and will give access to lights, rendering options, Fire etc. All can be invoked from within Fz.


  9. Just to add to my last post;

    Keep all you settings for the camera and emitters to real world settings. For example in interiors, a typical camera setting would be say fstop 2.8, ISO 400 and exteriors fstop 10, ISO 100.

    By switching on the MultiLight option, you can have fun altering the individual lights on the fly after the render is complete so I typically supply at least a day time and night shot from the same render.

    If your render is too dark for interiors then add more lights or ramp them up or change the camera settings. 

    I forgot to mention that there are also an Ambient field, and soft box light etc. as well to help with providing more light in an interior space.

    Basically the more lights the less noise. So I generally add "window emitters" to my openings pointing inwards on a layer. They are great to speed things up and add another element of control for interior renders.

  10. Hi Bo/John,

    There are different kinds of lights in Maxwell as per other packages. For outdoor sun/ambient lights there are Sky Dome, Physical Sky, IBL. You just need to tell FormZ in the Light parameters dialog which type the light is in the Type drop down menu.

    Other light types such as spots/cones created in your scene in Fz can be automatically converted by switching on "Export Point and Cone Lights" in the Maxwell Display Options under the Translation tab. But I like to create geometry for those and using an emitter material editable in Maxwell MXED. There you will find light types "Area, IES & Spot" where you can play with the settings. You need to go through the maxwell manual setup for this but it's fairly quick to set up and there's fantastic control using Maxwell Fire or MultiLight.

    I've attached a scene setup (simple interior screen for products or furniture). You only have to drop in you model, say a table for example.

    When creating the geometry (a simple square surface), make sure the normals are pointing in the direction you want it to shine. The size of the emitters affects the shadow softness.

  11. It all depends on the lens/camera used. There are FOV (Field Of View) calculators available on line which allow you to input the sensor size etc. to get the angle.

    But I prefer to align the views manually using known reference points. It's very important to set your Image Options to the same aspect ratio to the original photo. I usually make a copy of the original photo (6000x4000) and reduce it to say 2400x1600 before importing as a background image in Fz, it's quicker to load etc. and I can resize later before I go to render. Take this example below of an older project; I knew the position I took the shot and was able to draw a circle on the plan. Draw on a reference layer with known features, go to perspective view and use Edit cone of Vision to point and adjust the camera lining up the known features and plan, sometimes the spin needs adjusting as well. As a check you can see the focal comes out at 28.33mm with an angle of 64.86º. If I open the original photo and check its EXIF data the focal length is 18mm but remember that each lens used has a "multiplier" number. Mine just happens to be 1.6, so multiply the exif data focal length by 1.6 and you get 28.8 which is not far off at all considering the farther away the centre of interest there is a slight bend in the angle.

    Also consider your camera height (eye level), if you have the level of the ground level great but it usually needs adjusting as well.

    So going back to the Match View tool, I only use it as a starting point for some projects where I have modelled a certain amount of existing features accurately (not usually though) so I have points to snap to when lining it up. It can be hit and miss though.

  12. I usually use a 50mm lens with no zoom which gives a cone of vision of about 63º. I also mark my position of the camera on a map and set the camera from there.

    I also use google earth to grab an overview (or an imported location plan with features) and model in "anchors" (extruded objects) where known features are in the photo, that way I can just point the camera in the right direction, and fine adjust the angles and direction as needed.

    I find match view works best when more advance existing structures are modelled but that is not always the case, although it's great for matching aerial views as a starting point.
